example 1
[0035]Into a mash vessel, 30 kg of ground malt and 100 L of hot water were introduced, and protein rest and saccharification were carried out at temperatures in the range from 50° C. to 76° C. This saccharified liquid was filtered with a lauter, which was a filtration tank. After that, the liquid was transferred to a boiling kettle, and 10 kg of auxiliary ingredients mainly containing liquid sugar and 50 g of hops were added to this liquid. The volume of the liquid was adjusted to 160 L, and the liquid was boiled for 60 minutes. After the boiling, hot water was added in an amount equal to the amount of evaporated water. After hot trub was removed in a whirlpool tank, the liquid was cooled to 3° C. with a plate cooler. Thus, 170 L of cool wort was obtained. This cool wort was diluted by adding degassed water, and filtered through diatomaceous earth. Thus, clear wort was obtained. Carbon dioxide gas was dissolved in the wort to achieve a gas volume of 2.9. Thus, an unfermented beer-ta...

[0044]An unfermented beer-taste beverage was produced, and sensory evaluation was carried out in the same manner as that in Example 1, except that 3-methyl-2-butanethiol was used as the sulfur-containing compound instead of 3-methyl-2-butene-1-thiol. Table 2 shows the results. Note that each numeric value in the table shows an average value of evaluation data of each group.

[0045]As is apparent from the results of Tables 1 and 2, the addition of the sulfur-containing compounds at 1×102 ppt or more improved evaluations in terms of beer-likeness and fermentation flavor, and consequently greatly improved the palatability.
reference example 1
[0046]Three commercially available unfermented non-alcohol beer products (A, B, and C), and seven commercially available beer products (D, E, F, G, H, I, and J) were measured for the content of 3-methyl-2-butene-1-thiol (MBT) according to the method of Kishimoto et al., (Kishimoto, T. et al., Odorants comprising hop aroma of beer: hop-derived ordorants increased in the beer hopped with aged hops, Proceedings of the 31st EBC Comgress, Venice 2007). Table 3 shows the results.
TABLE 3ABCDEFGHIJMBT9.3 13.30.64.34.93.15.68.62.48.6(ppt)
[0047]As is apparent from Table 3, the contents of 3-methyl-2-butene-1-thiol in all of the unfermented non-alcohol beer products and the beer products were less than 1×102 ppt.
