Composition of Yaowan mung bean distilled liquor and manufacturing process thereof
InactiveCN101619283AProduction Technology ScienceScientifically and rationally develop strengths and avoid weaknessesAlcoholic beverage preparationFruit wineSugar
The invention relates to a composition of Yaowan mung bean distilled liquor and a manufacturing process thereof. The mung bean distilled liquor is prepared and blended by Daqu distilled liquor, traditional Chinese medicine juice and rock sugar, wherein the high-quality Daqu distilled liquor is 62-65 degrees and accounts for 56.56 percent; the traditional Chinese medicine juice accounts for 34.29 percent; the rock sugar accounts for 9.15 percent; and the blending ratio accuracies of the Daqu distilled liquo, the traditional Chinese medicine juice and the rock sugar respectively are plus or minus 0.5 percent. The composition of the Yaowan mung bean distilled liquor and the manufacturing process thereof scientifically and reasonably maximize favorable factors and minimize unfavorable ones on the basis of the traditional prescription to better adapt to different modern crowds and have the advantages of wine, fruit wine and tonic wine, therefore, the Yaowan mung bean distilled liquor is more mellow, fragrant and sweet, restorative and pure, and the production process thereof is more reasonable and scientific.
