Problems solved by technology

The defect of above-mentioned two kinds of methods is: 1. After beating or crushing jujube raw material, the suspended particles in the raw material liquid will increase, and the fruit wine is difficult to filter, and it is not easy to clarify; 2. Add pectinase to decompose pectin in the clarification process of fruit juice or fruit wine , so that the content of methanol in the product increases and the quality of the product decreases
3. The aging time is too short, the aroma substances of the fruit wine are not fully formed, and the flavor is poor

Embodiment 1

[0011] Example 1. A kind of jujube wine, described jujube wine is dry type jujube wine, is light rose red or red, is clear and transparent, has fresh and pleasant fruit flavor, and wine body is complete, and alcohol content is 6~12% (20 ℃ V / V ), total sugar (calculated as glucose) ≤ 4g / L, titratable acid (calculated as total acid) 5-8g / L, free sulfur dioxide ≤ 50mg / L.

Embodiment 2

[0012] Example 2. A kind of jujube wine, described jujube wine is semi-dry jujube wine, is light rose red or red, is clear and transparent, has fresh and pleasant fruit fragrance, and wine body is complete, and alcohol content is 6~12% (20 ℃ V / V), total sugar (calculated as glucose) 4.1-12.0g / L, titratable acid (calculated as total acid) 5-8g / L, free sulfur dioxide ≤ 50mg / L.

Embodiment 3

[0013] Example 3. A jujube wine, said jujube wine is semi-sweet jujube wine, pale rose red or red, clear and transparent, with sweet and mellow taste and aged wine aroma, harmonious sweet and sour, and full-bodied. Alcohol content 6-12% (20°C V / V), total sugar (calculated as glucose) 12.1-50.0g / L, titratable acid (calculated as total acid) 5-8g / L, free sulfur dioxide ≤ 50mg / L.

Abstract

The invention relates to red date wine and brewing method. The red date wine is light rose red or red, transparent, has pure red date sweet smell and bouquet. The alcohol content is 6-12%(20 degree centigrade V / V), total sugar 3-100g / L, titration acid 5-8g / L, dissociating sulfur dioxide <=50mg / L. The method includes full fruit dipping and clean juice fermenting processes. Pectinase would not be added in to improve the quality of the product. After main fermenting, aging for 4-6 months, the wine would be prepared. The invention has great meaning for sustainable development and society evolving for red date producing area.

Description

Technical field [0001] The invention relates to jujube wine and a brewing method thereof, belonging to the technical field of brewing science and engineering. Background technique [0002] my country is the largest producer of jujube in the world. At present, it is mainly eaten fresh, and only a small amount is used for processing fruit juice and sugar products, but the added value is not high. Using jujube as raw material, jujube wine is brewed through microbial fermentation, which has unique flavor and nutritional components, and will become a very competitive commodity in domestic and foreign markets. The traditional jujube wine brewing generally uses beating and pectinase to extract the juice or the fruit is crushed and then added with water for direct fermentation. In the prior art, the publication number is CN1408838A, and the Chinese patent application with the application number 02132873.0 discloses a patent document called "A Production Method for Jujube Wine".
