In other words, unless otherwise specified, the term "beer-taste beverage" as used herein encompasses any beverage that has a beer flavor. Therefore, "beer-flavored beverages" include not only beer and beer-flavored beverages, which are malt-fermented alcoholic beverages obtained by fermenting malt, hops, and water using yeast, but also fermented alcoholic beverages (fermented beer-flavored beverages) obtained by fermenting hops and water using yeast without using malt, and non-fermented alcoholic beverages (non-fermented beer-flavored beverages) obtained by fermenting hops and water using yeast without using malt, and beer flavorings containing aroma components such as esters, higher alcohols, and lactones, without using malt.

[0010] Examples of aroma components contained in beer flavorings include isoamyl acetate, ethyl acetate, n-propanol, isobutanol, acetaldehyde, ethyl caproate, ethyl caprylate, isoamyl propionate, linalool, geraniol, citral, 4-vinylguaiacol (4-VG), 4-methyl-3-pentenoic acid, 2-methyl-2-pentenoic acid, 1,4-cineole, 1,8-cineole, 2,3-diethyl-5-methylpyrazine, γ-decanolactone, γ-undecalactone, and ethyl hexanoate. ethanol, ethyl 2-methylbutyrate, ethyl n-butyrate, myrcene, citral, limonene, maltol, ethyl maltol, phenylacetic acid, furaneol, furfural, methional, 3-methyl-2-butene-1-thiol, 3-methyl-2-butanethiol, diacetyl, ferulic acid, geranic acid, geranyl acetate, ethyl butyrate, octanoic acid, decanoic acid, 9-decenoic acid, nonanoic acid, tetradecanoic acid, propanoic acid, 2-methylpropanoic acid, γ-butyrolactone, 2-aminoacetophenone, 3-phenylpropanoic acid Ethyl pionate, 2-ethyl-4-hydroxy-5-methyl-3(2H)-furanone, dimethyl sulfone, 3-methylcyclopentane-1,2-dione, 2-methylbutanal, 3-methylbutanal, 2-methyltetrahydrofuran-3-one, 2-acetylfuran, 2-methyltetrahydrofuran-3-one, hexanal, hexanol, cis-3-hexenal, 1-octen-3-ol, β-eudesmol, 4-mercapto-4-methylpentan-2-one, β-caryophyllene, β-myl Examples of such compounds include acene, furfuryl alcohol, 2-ethylpyrazine, 2,3-dimethylpyrazine, 2-methylbutyl acetate, isoamyl alcohol, 5-hydroxymethylfurfural, phenylacetaldehyde, 1-phenyl-3-buten-1-one, trans-2-hexenal, nonanal, phenethyl alcohol, β-damascenone, menthone, menthyl acetate dimethyl trisulfide, 2-ethyl-3,5-dimethylpyrazine, cis-3-hexenol, γ-terpinene, and cis-linalool oxide.

[0011] The fermented beer-flavored beverage may be a top-fermented beer-flavored beverage (ale beer-flavored beverage) brewed through a fermentation process using a top-fermenting yeast (such as Saccharomyces), a bottom-fermented beer-flavored beverage (lager beer-flavored beverage, pilsner beer-flavored beverage) brewed through a fermentation process using a bottom-fermenting yeast (such as Saccharomyces), or a blend of these beer-flavored beverages. Furthermore, the fermented beer-flavored beverage may be obtained by using top-fermenting yeast and bottom-fermenting yeast in the same fermentation process or in separate fermentation processes. Furthermore, "fermentation" as used herein may refer to alcoholic fermentation, which produces alcohol, or non-alcoholic fermentation, which does not produce alcohol.

[0012] In addition, the beer-taste beverage, which is one embodiment of the alcoholic beverage of the present invention, may be a malt-based beer-taste beverage that uses malt as an ingredient, or a malt-free beer-taste beverage that does not use malt. The beer-taste beverage, which is one embodiment of the alcoholic beverage of the present invention, may be a malt-free beer-taste beverage that does not substantially use malt as a raw material. In this specification, "not substantially using malt" means that malt is not actively used as a raw material when producing the alcoholic beverage, and includes embodiments in which malt is inevitably mixed in during production. Additionally, whether or not malt is actively used as an ingredient can be confirmed from the ingredient labeling established by the Liquor Tax Act, Food Labeling Act, Food Sanitation Act, JAS Act, Act against Unjustifiable Premiums and Misleading Representations, Health Promotion Act, or rules and voluntary standards established by industry groups. For example, if malt is actively used as an ingredient, the ingredient name will be listed as "malt." On the other hand, beverages that "do not substantially use malt" will not list "malt" as an ingredient name on the ingredient labeling. Furthermore, the beer-flavored beverage, which is one embodiment of the alcoholic beverage of the present invention, may be a barley-based beer-flavored beverage that uses unmalted barley (e.g., barley, wheat, etc.) as a raw material, or a barley-free beer-flavored beverage that does not use barley.

[0013] When the alcoholic beverage of one embodiment of the present invention is an alcohol-containing beer-taste beverage, from the viewpoint of improving the drinkability suitable for an alcoholic beverage, the alcohol content (ethanol content) may be 1.0 (v / v)% or more, 1.2 (v / v)% or more, 1.5 (v / v)% or more, 1.7 (v / v)% or more, 2.0 (v / v)% or more, 2.2 (v / v)% or more, 2.5 (v / v)% or more, 2.7 (v / v)% or more, 3.0 (v / v)% or more, 3.2 (v / v)% or more, 3.5 (v / v)% or more, 3.7 (v / v)% or more, 4.0 (v / v)% or more, 4.2 (v / v)% or more. , 4.5(v / v)% or more, 4.7(v / v)% or more, or 5.0(v / v)% or more, and may also be 5.2(v / v)% or more, 5.5(v / v)% or more, 5.7(v / v)% or more, 6.0(v / v)% or more, 6.2(v / v)% or more, 6.5(v / v)% or more, 6.7(v / v)% or more, 7.0(v / v)% or more, 7.2(v / v)% or more, 7.5(v / v)% or more, 7.7(v / v)% or more, 8.0(v / v)% or more, 8.2(v / v)% or more, 8.5(v / v)% or more, 8.7(v / v)% or more, or 9.0(v / v)% or more. Furthermore, from the viewpoint of reducing the pungency unsuitable for alcoholic beverages, the alcohol content is preferably 20.0(v / v)% or less, 19.0(v / v)% or less, 18.0(v / v)% or less, 17.0(v / v)% or less, 16.0(v / v)% or less, 15.0(v / v)% or less, 14.0(v / v)% or less, 13.0(v / v)% or less, 12.0(v / v)% or less, 11.0(v / v)% or less, 10.0(v / v)% or less, or 9.5(v / v)% or less.

[0015] In this specification, the alcohol content is expressed as a percentage on a volume / volume basis ((v / v)%). The alcohol content of a beverage can be measured by any known method, for example, using a vibration density meter.

[0016] Furthermore, the alcohol content of a beer-taste beverage, which is one embodiment of the alcoholic beverage of the present invention, can be determined by a variety of factors, including the addition of dilution water or carbonated water and the amount thereof, the type of raw materials (barley, malt, corn grits, sugar solution, etc.), the amount of raw materials, the type of enzyme, the amount of enzyme added, the timing of enzyme addition, the saccharification time in the mash tank, the proteolysis time in the mash tank, the pH in the mash tank, the pH in the mashing process (the wort production process from the addition of malt to before the addition of yeast), the amount of acid added when adjusting the pH, and the timing of pH adjustment (during mashing, during fermentation, at the completion of fermentation, after mashing, etc.). The desired range can be adjusted by appropriately setting the following: (i) the temperature setting and holding time for each temperature range when preparing wort (including during saccharification), the original extract concentration of the pre-drinking liquid (pre-fermentation liquid), the original extract concentration during the fermentation process, the fermentation conditions (oxygen concentration, aeration conditions, yeast variety, amount of yeast added, number of yeast grown, timing of yeast removal, fermentation temperature, fermentation time, pressure setting, carbon dioxide concentration, etc.), whether or not spirits, brewer's alcohol, etc. are added, and if so, the amount to be added.

[0017] The beer-taste beverage, which is one embodiment of the alcoholic beverage of the present invention, may contain grain-derived spirits (distilled alcoholic beverages) as the alcohol component in order to adjust the alcohol content to fall within the above range. In this specification, spirits refers to alcoholic beverages obtained by saccharifying grains such as barley, rice, buckwheat, corn, potatoes, and sugarcane using malt or, if necessary, an enzyme agent, fermenting the grains using yeast, and then distilling the saccharified grains. As the grains used as the raw material for spirits, plants belonging to the grass family are preferred, and barley is more preferred. Furthermore, the beer-flavored beverage, which is one embodiment of the alcoholic beverage of the present invention, may be a beverage that does not contain spirits, from the perspective of being a low-alcohol beer-flavored beverage that has a good taste and resembles beer.

[0018] The beer-taste beverage, which is one embodiment of the alcoholic beverage of the present invention, may be a beer-taste beverage in which the malt ratio (the ratio of all malts used) is limited in order to reduce the heavy taste that is unsuitable for alcoholic beverages. Specifically, the malt ratio of the beer-taste beverage, which is one embodiment of the alcoholic beverage of the present invention, may be less than 100% by mass, 95% by mass or less, 90% by mass or less, 85% by mass or less, 80% by mass or less, 75% by mass or less, 70% by mass or less, 69% by mass or less, 68% by mass or less, 67% by mass or less, less than 67% by mass, 66.6% by mass or less, 66% by mass or less, 65% by mass or less, 64% by mass or less, 63% by mass or less, 62% by mass or less, 61% by mass or less, 60% by mass or less, less than 60% by mass, 59% by mass or less, 58 ...58% by mass or less, 58% by mass or less, 58% by mass or less, 58% by mass or less, 58% by mass or less, 58% by mass or less, 58% by mass or less, 58% by mass or less, % or less, 57 mass% or less, 56 mass% or less, 55 mass% or less, 54 mass% or less, 53 mass% or less, 52 mass% or less, 51 mass% or less, 50 mass% or less, less than 50 mass%, 45 mass% or less, 40 mass% or less, 35 mass% or less, 30 mass% or less , 25% by mass or less, less than 25% by mass, 20% by mass or less, 15% by mass or less, 10% by mass or less, 5% by mass or less, 1% by mass or less, 0.5% by mass or less, 0.1% by mass or less, 0.01% by mass or less, 0.001% by mass or less, or 0% by mass. The beer-flavored beverage, which is one embodiment of the alcoholic beverage of the present invention, is a beverage in which the malt ratio is restricted, but the alcohol content is adjusted to a certain range, and the contents of acetaldehyde and ethyl acetate are adjusted, thereby improving the taste (e.g., drinkability and flavor) that is characteristic of an alcoholic beverage. The malt ratio of a beer-taste beverage, which is one embodiment of the alcoholic beverage of the present invention, may be a certain value or more within a range that does not impair the effects of the present invention, and may be, for example, 1% by mass or more, 5% by mass or more, 10% by mass or more, 15% by mass or more, 20% by mass or more, 25% by mass or more, 30% by mass or more, 35% by mass or more, 40% by mass or more, 45% by mass or more, 50% by mass or more, 51% by mass or more, 52% by mass or more, 53% by mass or more, 54% by mass or more, 55% by mass or more, 56% by mass or more, 57% by mass or more, 58% by mass or more, 59% by mass or more, 60% by mass or more, 65% by mass or more, 70% by mass or more, or 75% by mass or more.

[0019] In this specification, "malt ratio" means a value calculated in accordance with the Liquor Tax Act and the Interpretation Notice of Liquor Administration-related Laws and Regulations, etc., which came into effect on April 1, 2018. When the malt ratio is reduced, it is preferable to increase the amount of raw materials (carbon source, nitrogen source) other than malt that can be assimilated by yeast. Examples of carbon sources that can be assimilated by yeast include monosaccharides, disaccharides, trisaccharides, and sugar solutions thereof, while examples of nitrogen sources include yeast extract, soy protein, malt, soybeans, yeast extract, peas, wheat germ, ungerminated grains, and decomposition products thereof. Here, wheat malt may be used, but from the viewpoint of allergens, it is preferable not to use wheat malt. Examples of ungerminated grains include ungerminated barley, wheat, rye, oats, oats, pearl millet, rice (white rice, brown rice, etc.), corn, sorghum, potatoes, beans (soybeans, peas, etc.), buckwheat, sorghum, millet, barnyard millet, etc. Starches obtained from these grains and extracts thereof may also be used.

[0020] The beer-taste beverage, which is one embodiment of the alcoholic beverage of the present invention, may be a beer-taste beverage produced by fermentation under conditions in which the original extract concentration is high. Beer-taste beverages produced through such high-concentration fermentation may contain greater amounts of aroma components such as acetaldehyde and ethyl acetate than beer-taste beverages produced under normal fermentation conditions. In a beer-taste beverage, which is one embodiment of the alcoholic beverage of the present invention, the acetaldehyde content is, from the perspective of improving a suitable, soft aroma (the lingering aroma and fullness of the aroma of the alcoholic beverage) even in an alcoholic beverage with a limited malt ratio, 0.1 mg / L or more, 0.5 mg / L or more, 1.0 mg / L or more, 1.2 mg / L or more, 1.4 mg / L or more, 1.6 mg / L or more, 1.8 mg / L or more, 2.0 mg / L or more, 2.2 mg / L or more, 2.4 mg / L or more, 2.6 mg / L or more, 2.8 mg / L or more, 3.0 mg / L or more, 3.2 mg / L or more, 3.4 mg / L or more, 3.6 mg / L or more, 3.8 mg / L or more, 4.0 mg / L or more, 4.2 mg / L or more, 4.4 mg / L or more, 4.6 mg / L or more, 4.8 mg / L or more, 5.0 mg / L or more, 5.2 mg / L or more, 5.

[0034] The free amino nitrogen content of the beer-taste beverage, which is one embodiment of the alcoholic beverage of the present invention, can be controlled by adjusting the amount of raw materials used that can be assimilated by yeast. Specifically, the free amino nitrogen content can be easily adjusted by adjusting the amount of malt, etc., which has a high nitrogen content. Examples of raw materials with a high nitrogen content include malt, soybeans, yeast extract, peas, and ungerminated grains.

Furthermore, from the viewpoint of preventing the alcoholic beverage from having a heavy taste, the upper limit of the total polyphenol content may be set to 500.0 mg / L or less, 450.0 mg / L or less, 400.0 mg / L or less, 350.0 mg / L or less, 300.0 mg / L or less, 250.0 mg / L or less, 200.0 mg / L or less, 180.0 mg / L or less, 160.0 mg / L or less, 140.0 mg / L or less, 120.0 mg / L or less, 110.0 mg / L or less, 100.0 mg / L or less, 95.0 mg / L or less, 90.0 mg / L or less, 85.0 mg / L or less, 80.0 mg / L or less, 75.0 mg / L or less, or 70.0 mg / L or less.

[0036] In this specification, the term "total amount of polyphenols" refers to the total amount of polyphenols contained in the entire amount (100% by mass) of an alcoholic beverage. Polyphenols refer to compounds in which two or more hydrogen atoms of an aromatic hydrocarbon have been substituted with hydroxyl groups, and specific examples include flavonols, isoflavones, tannins, catechins, quercetin, anthocyanins, and the like. In this specification, the amount of total polyphenols can be measured by the method described in the Revised BCOJ Beer Analysis Method (published by the Brewery Association of Japan, a public interest incorporated foundation, edited by the International Technical Committee of the Brewers Association of Japan (Analysis Committee), revised and expanded in 2013).

[0037] The total amount of polyphenols can be controlled by adjusting the amount of raw materials with a high polyphenol content, such as barley malt and malt husks (grain husks). Generally, malt containing husks (grain husks) has a high polyphenol content, while soybeans, yeast extract, wheat, wheat malt, etc. have a low polyphenol content. By appropriately selecting such raw materials and adjusting the amounts used, it is possible to adjust the polyphenol content within a desired range.

[0038] In a beer-taste beverage that is one embodiment of the alcoholic beverage of the present invention, the original extract concentration (original wort extract concentration) of the final beer-taste beverage is, from the viewpoint of enhancing the desired depth of flavor, preferably 5.0% by mass or more, 5.2% by mass or more, 5.5% by mass or more, 5.7% by mass or more, 6.0% by mass or more, 6.2% by mass or more, 6.5% by mass or more, 6.7% by mass or more, 7.0% by mass or more, 7.2% by mass or more, 7.5% by mass or more, 7.7% by mass or more, 8.0% by mass or more, 8.2% by mass or more, 8.5% by mass or more, 8.7 ... It is preferable that the content be 0.2% by mass or more, 8.5% by mass or more, 8.7% by mass or more, or 9.0% by mass or more, and it may also be 20.0% by mass or less, 19.0% by mass or less, 18.0% by mass or less, 17.0% by mass or less, 16.0% by mass or less, 15.5% by mass or less, 15.0% by mass or less, 14.5% by mass or less, 14.0% by mass or less, 13.5% by mass or less, 13.0% by mass or less, 12.5% ​​by mass or less, 12.0% by mass or less, 11.5% by mass or less, or 11.0% by mass or less. The "original extract concentration" in this specification can be measured by the method described in "BCOJ Beer Analysis Methods (published by the Brewery Society of Japan, edited by the Brewers Association of Japan, revised edition November 1, 2004)."

In this specification, the "color" of an alcoholic beverage can be measured by the measurement method described in "8.8 Color" of the Revised BCOJ Beer Analysis Methods (published by the Brewery Association of Japan, edited by the International Technical Committee of Brewers Association (Analysis Committee), 2013, expanded and revised). The "color" is specified by the color unit (EBC unit) established by the European Brewery Convention. The smaller the value, the lighter the beverage, and conversely, the larger the value, the darker the beverage. The color of an alcoholic beverage can be controlled by, for example, appropriately adjusting the type of malt used, the blending ratio when two or more types of malt are used, the boiling conditions when preparing the pre-beverage solution (pre-fermentation solution), etc. More specifically, for example, to increase the color, adjustments can be made by increasing the blending ratio of dark-colored malt as malt, increasing the temperature during boiling, extending the boiling time, and performing decoction when preparing the saccharified solution. Furthermore, the color can also be adjusted to be higher by increasing the original extract concentration or the malt ratio.

[0044] The pH of the beer-taste beverage, which is one embodiment of the alcoholic beverage of the present invention, is preferably 2.0 or higher, 2.2 or higher, 2.4 or higher, 2.6 or higher, 2.8 or higher, 3.0 or higher, 3.1 or higher, 3.2 or higher, 3.3 or higher, 3.4 or higher, 3.5 or higher, 3.6 or higher, 3.7 or higher, 3.8 or higher, 3.9 or higher, or 4.0 or higher, and is preferably 5.4 or lower, 5.2 or lower, 5.0 or lower, 4.9 or lower, 4.8 or lower, 4.7 or lower, 4.6 or lower, 4.55 or lower, 4.5 or lower, 4.4 or lower, 4.3 or lower, 4.2 or lower, or 4.1 or lower.

[0045] 1.1 Raw materials The main ingredients of the alcoholic beverage of the present invention can be those commonly used in various alcoholic beverages. When the alcoholic beverage of one embodiment of the present invention is a beer-taste beverage that uses malt, the main ingredients are malt and water. When the alcoholic beverage of one embodiment of the present invention is a beer-taste beverage that does not substantially use malt, the main ingredients are a carbohydrate material such as sugar solution and water. Furthermore, these beer-taste beverages may be beverages that use hops or beverages that do not use hops. In addition, preservatives, sweeteners, water-soluble dietary fiber, bittering agents or bitterness imparting agents, antioxidants, flavorings, acidulants, salts, etc. may be used.

[0046] 1.1.1 Malt and non-malt grains When malt is used as a raw material, the malt refers to seeds of wheat or barley, such as barley, wheat, rye, oats, oats, adlay, or oats, which have been germinated, dried, and have their roots removed, and may be of any origin or variety. The malt used in one embodiment of the present invention is preferably barley malt. Barley malt is one of the malts most commonly used as a raw material for beer-flavored beverages in Japan. There are various types of barley, such as two-row barley and six-row barley, and either may be used. Furthermore, in addition to regular malt, colored malt may also be used. When colored malt is used, different types of colored malt may be used in appropriate combination, or a single type of colored malt may be used.

[0047] In addition, in a beer-taste beverage, which is one embodiment of the alcoholic beverage of the present invention, the malt used is preferably selected appropriately depending on the desired color of the beer-taste beverage, and the malt selected may be a single type or two or more types may be selected in combination.

[0048] Additionally, grains other than malt may be used together with or instead of malt. Examples of such grains include barley, wheat, rye, oats, oats, pearl millet, oats, etc. that do not fall under the category of malt, rice (white rice, brown rice, etc.), corn, koryan, potatoes, beans (soybeans, peas, etc.), buckwheat, sorghum, millet, barnyard millet, and starches obtained from these, as well as extracts of these.

[0049] Furthermore, when the malt ratio is reduced or malt is not used, it is preferable to increase the amount of raw materials (carbon source, nitrogen source) other than malt that can be assimilated by yeast. The raw materials that can be assimilated by yeast are as described above.

[0050] Fruits, fruit skins, bark, leaves, flowers, stems, roots and seeds of plants other than grasses such as wheat that can be used as raw materials can be appropriately selected. Specific examples of plants other than grasses include citrus fruits, soft fruits, herbs, spices, etc. Citrus fruits include oranges, yuzu, lemons, limes, mandarins, grapefruits, iyokan, kumquats, kabosu, bitter oranges, shikuwasa, and sudachi. Soft fruits include peaches, grapes, bananas, apples, grapes, pineapples, strawberries, pears, muscat grapes, blackcurrants, etc. Herbs and spices include coriander, pepper, fennel, Sichuan pepper, Japanese pepper, cardamom, caraway, nutmeg, mace, juniper berries, allspice, vanilla, elderberries, grains of paradise, anise, star anise, etc. These may be used as they are, or may be crushed before use, or may be used in the form of an extract extracted with an extraction solvent such as water or ethanol, or may be used in the form of squeezed juice (such as fruit juice).These may be used alone or in combination of two or more kinds. While the above can be used as appropriate according to consumer preferences, to enjoy a clean, refreshing taste, it is preferable to avoid using any of the above citrus fruits, soft fruits, herbs, and spices as ingredients, or to use only the minimum amount of them. In particular, because black currant imparts an undesirable milky aroma to beer, it is preferable to avoid using any black currant or black currant juice as ingredients, or to use only the minimum amount.

[0051] 1.1.2 Hop When hops are used in one embodiment of the present invention, the form of the hops may be, for example, pelleted hops, powdered hops, hop extract, etc. Furthermore, the hops used may also be processed hop products such as isomerized hops and reduced hops. When hops are used in one embodiment of the present invention, the amount of hops added is adjusted appropriately, but is preferably 0.0001 to 1% by mass based on the total amount (100% by mass) of the raw materials for the beverage.

[0052] Furthermore, alcoholic beverages such as beer-flavored beverages that use hops as an ingredient contain iso-α acids, which are components derived from hops. The content of iso-α acids in beverages that use hops may be greater than 0.1 ppm by mass or greater than 1.0 ppm by mass based on the total amount (100% by mass) of the beverage. On the other hand, the content of iso-α acids in a beverage that does not use hops may be 0.1 ppm by mass or less based on the total amount (100% by mass) of the beverage. In this specification, the content of iso-α acids refers to the value measured by the high-performance liquid chromatography (HPLC) analysis method described in the Revised BCOJ Beer Analysis Method (published by the Brewery Association of Japan, a public interest incorporated foundation, edited by the International Technical Committee of the Brewers Association of Japan (Analysis Committee), revised and expanded in 2013).

These sweeteners may be used alone or in combination of two or more. These sugars may be in the form of a liquid such as a solution, or a solid such as a powder. There are also no particular limitations on the type of grain from which starch is produced, the starch purification method, or the conditions for enzymatic or acidic hydrolysis. For example, sugars with an increased maltose content may be used by appropriately setting the conditions for enzymatic or acidic hydrolysis. Other sugars that can be used include sucrose, fructose, glucose, maltose, trehalose, maltotriose, maltotetraose, isomaltose, isomaltotriose, isomaltotetraose, panose, and solutions thereof (sugar solutions). Examples of artificial sweeteners include aspartame, acesulfame potassium (acesulfame K), sucralose, and neotame.

[0056] 1.1.5 Soluble dietary fiber The beer-taste beverage, which is one embodiment of the alcoholic beverage of the present invention, may be a beverage containing water-soluble dietary fiber, or may be a beverage containing no water-soluble dietary fiber (added thereto). Examples of water-soluble dietary fibers include indigestible dextrin, polydextrose, hydrolyzed guar gum, pectin, glucomannan, alginic acid, laminarin, fucoidin, and carrageenan.

[0078] Hereinafter, a method for producing a fermented alcoholic beverage and a method for producing a non-fermented alcoholic beverage according to one embodiment of the present invention will be described.

[0079] 2.1 Method for producing fermented alcoholic beverages One embodiment of the method for producing a fermented alcoholic beverage of the present invention includes a method that involves a fermentation process using yeast, and includes the following steps (1) and (2) in addition to the steps (a) to (c) described above. Step (1): A step of obtaining a pre-beverage solution by using various raw materials and performing at least one of saccharification, boiling, and solid content removal. Step (2): A step of adding yeast to the pre-beverage liquid obtained in step (1) to carry out alcoholic fermentation.

[0080] Furthermore, in one embodiment of the method for producing a fermented alcoholic beverage of the present invention, the above steps (a) to (c) and adjustments of the pyroglutamic acid content, total nitrogen content, free amino nitrogen content, total polyphenol content, original extract concentration, bitterness value, color, and pH can be performed at one or more of the following times (A) to (C). Furthermore, if steps (a) to (c) and the above-mentioned adjustments can be performed simultaneously by performing steps (1) and (2), there is no need to perform these steps separately. (A): Simultaneously with at least one of step (1) and step (2) (A): Between step (1) and step (2) (C): After step (2) Each step in the method for producing a fermented alcoholic beverage according to one embodiment of the present invention will be described below.

[0081] 2.1.1 Process (1) Step (1) is a step in which various raw materials are subjected to at least one of saccharification, boiling, and solid content removal treatments to obtain a pre-beverage solution. For example, when malt is used as the various raw materials, water, malt, and various raw materials including various carbohydrate raw materials other than malt are charged into a mash kettle or mash tank, and enzymes such as amylase are added as necessary. Various additives such as hops, preservatives, sweeteners, water-soluble dietary fiber, bittering agents or bitterness imparting agents, antioxidants, flavorings, acidulants, and colorings may be added as the various raw materials other than malt. These may be added before, during, or after the saccharification treatment. Alternatively, they may be added after the fermentation in the subsequent step.

[0082] The mixture of various raw materials is heated to saccharify the starch in the raw materials. The temperature and time of saccharification treatment are preferably adjusted appropriately taking into consideration the type of malt used, the malt ratio, water and raw materials other than malt, the type and amount of enzyme used, the concentration of raw wort extract in the final beverage, etc. For example, in one embodiment of the present invention, the saccharification treatment temperature may be 55 to 75°C, and the saccharification treatment time may be 30 to 240 minutes.

[0083] It is preferable to subject this saccharified solution to a boiling treatment. When hops, bittering agents, etc. are used as raw materials during this boiling treatment, it is preferable to add these agents. Hops, bittering agents, etc. may be added between the start and end of boiling of the saccharified solution.

[0084] After the boiling treatment, the liquor is preferably transferred to a whirlpool, cooled to 0 to 23°C, and then treated to remove solids such as coagulated proteins. This treatment allows the concentration of the raw wort extract to be adjusted. In this way, a beverage pre-liquid is obtained. In this step, filtration through a filter with a predetermined pore size (for example, a pore size of less than 30 μm) may be performed to remove solid content.

[0085] Instead of the saccharified solution, a pre-drink solution (pre-fermentation solution) may be prepared by adding hops, bittering agents, etc. to malt extract and warm water, followed by boiling. Furthermore, when malt is not used as one of the various raw materials, a liquid sugar containing a carbon source, a nitrogen source as an amino acid-containing raw material other than barley or malt, hops, dietary fiber, preservatives, sweeteners, antioxidants, bittering agents, flavorings, acidulants, colorants, etc. may be mixed with warm water to prepare a liquid sugar solution, which may then be boiled to prepare a pre-beverage liquid (pre-fermentation liquid). When hops are used, they may be added before the boiling treatment or between the start and end of boiling of the liquid sugar solution.

[0086] 2.1.2 Process (2) Step (2) is a step of adding yeast to the pre-beverage solution obtained in step (1) to carry out alcoholic fermentation. The yeast used in this step can be appropriately selected taking into consideration the type of alcoholic beverage to be produced, the desired flavor and fermentation conditions, etc., and either top-fermenting yeast or bottom-fermenting yeast may be used.

[0087] The yeast may be added to the raw material solution as a yeast suspension, or may be added to the raw material solution as a slurry obtained by concentrating the yeast by centrifugation or sedimentation. Alternatively, the yeast may be added after centrifuging and completely removing the supernatant. The amount of yeast added to the raw material solution can be determined as appropriate, but for example, 5.0 × 10 6 cells / ml ~ 1.0 × 10 9 It is about cells / ml.

[0088] The fermentation conditions for fermentation can be set as appropriate, but from the perspective of adjusting the alcohol content of the fermented alcoholic beverage within the above-mentioned range, the fermentation temperature is preferably 5 to 25°C (more preferably 10 to 22°C). The alcohol content of the fermented alcoholic beverage can be adjusted by appropriately setting the type, amount, and timing of addition of polysaccharide-degrading enzymes such as transglucosidase and glucoamylase. Furthermore, the temperature (increase or decrease) or pressure of the fermentation liquid may be changed during the fermentation process, as necessary.

[0089] After fermentation, a filtration treatment may be carried out to remove yeast from the fermented alcoholic beverage, or a filtration treatment may not be carried out. Furthermore, water and the various additives described above may be added as needed.

[0090] The fermented alcoholic beverage according to one embodiment of the present invention thus obtained is filled into a predetermined container and distributed on the market as a finished product. The method for packaging the fermented alcoholic beverage is not particularly limited, and any packaging method known to those skilled in the art can be used.

Containers of any shape and material may be used in the packaging step, and examples of containers include those described in "1.4 Packaged Beverages."

[0091] 2.2 Methods for producing non-fermented alcoholic beverages The method for producing a non-fermented alcoholic beverage according to one embodiment of the present invention may be any method that does not involve a fermentation step, and examples thereof include a method comprising the following steps (1) and (3). Step (1): A step of obtaining a pre-beverage solution by using various raw materials and performing at least one of saccharification, boiling, and solid content removal. Step (3): A step of cooling the pre-beverage liquid obtained in step (1) and adding carbon dioxide gas.

[0092] Step (1) is the same as step (1) for obtaining a pre-drink solution in the above-mentioned "method for producing a fermented alcoholic beverage." Carbon dioxide gas may be added in step (3) by mixing the cooled beverage preliminaries obtained in step (1) with carbonated water, or by directly adding carbon dioxide gas to the cooled beverage concentrate. Furthermore, additives such as preservatives, sweeteners, flavors, acidulants, and colorants may be added as needed when adding carbon dioxide gas at the same time as step (3).

[0093] Furthermore, a method for producing a non-fermented alcoholic beverage according to one embodiment of the present invention includes the following step (3a): Step (3a): A step of blending an alcohol component after at least step (1).

[0094] Step (3a) may be carried out at least after step (1), and may be carried out, for example, at one or more of the following times (α), (β), and (γ): (α): Between step (1) and step (3) (β): Simultaneous with step (3) (γ): After step (3) Among these, step (3a) is preferably carried out after the beverage pre-liquid obtained in step (1) is cooled to prepare a cooled beverage concentrate, and before adding carbon dioxide gas. The alcohol component to be added in step (3a) is preferably spirits (distilled alcohol) derived from the above-mentioned grains.

[0095] Furthermore, in one embodiment of the method for producing a non-fermented alcoholic beverage of the present invention, the above steps (a) to (c) and adjustment of the pyroglutamic acid content, total nitrogen content, free amino nitrogen content, total polyphenol content, bitterness value, color, and pH can be performed at one or more of the following times (i) to (v).

[0121] Examples 45 to 53 <Beverage preparation> 40 kg of crushed barley malt was placed in a mash tank containing 200 L of hot water maintained at 50°C. The temperature was gradually increased and maintained until it reached 78°C, after which the malt residue was removed by filtration to obtain a saccharified solution. Next, a sugar solution was added to the saccharified solution to achieve the malt ratio shown in Table 14, and hops were then added. The mixture was boiled and subjected to solid-liquid separation to obtain a clear wort. The wort was then cooled to obtain a pre-beverage solution (pre-fermentation solution), which was inoculated with a polysaccharide-degrading enzyme and top-fermenting yeast and subjected to alcoholic fermentation. After fermentation to an alcohol content of approximately 12% (v / v), the mixture was diluted to an alcohol content shown in Table 14, and the yeast was removed by filtration to obtain a malt-based alcoholic beverage (fermented beer-flavored beverage). The original extract concentration of the obtained beverage was 10.0 to 12.0 mass%, the total nitrogen content was 40 to 60 mg / 100 mL, the free amino nitrogen content was 4 to 10 mg / 100 mL, the total polyphenol content was 90 to 110 mg / L, and the color was 10 to 20 EBC. In each example, the set temperature and holding time of each temperature range when preparing the saccharified solution, the amount and timing of addition of the polysaccharide-degrading enzyme, the type of hop, the amount and timing of addition, and the fermentation temperature and time were appropriately set to adjust the acetaldehyde content, ethyl acetate content, pyroglutamic acid content, and bitterness value to the values ​​shown in each table. The contents of acetaldehyde, ethyl acetate, and pyroglutamic acid were adjusted by directly adding these substances as necessary. The resulting beverages were subjected to sensory evaluation in the same manner as in Examples 1 to 44. The results are shown in Table 14.

[0122] [Table 14]

[0123] As can be seen from Tables 1 to 14, the fermented beer-flavored beverages prepared in Examples 1 to 53 were superior to the beverages of the comparative examples in the various evaluation items described above, even when the malt ratio was limited to a certain value or less, by adjusting the alcohol content, acetaldehyde content, and ethyl acetate content to within specified numerical ranges, and were beverages with an overall excellent flavor. On the other hand, the fermented beer-flavored beverages prepared in Comparative Examples 1 to 24 did not meet the specified numerical ranges for alcohol content, acetaldehyde content, or ethyl acetate content, and therefore were inferior in one or more of the above-mentioned evaluation items. Furthermore, the fermented beer-taste beverage of Comparative Example 25, which was prepared under normal fermentation conditions, did not satisfy the specified numerical ranges for both the acetaldehyde content and the ethyl acetate content, and the content of these aroma components was lower than that of the beverages of each Example, which were fermented under so-called high-concentration fermentation conditions using a pre-fermentation liquid with a high original extract concentration.
