Abstract
The invention discloses Baijiu produced by using Xiaoqu Fen-flavor liquor distillers' grains and a production method of the Baijiu, and belongs to the technical field of Baijiu brewing. According to the production method disclosed by the invention, the Xiaoqu Fen-flavor liquor distillers' grains with abundant nutrient substances are used as a fermentation grain source; at the early stage, a bacteria culture and fermentation technology of the Xiaoqu Fen-flavor liquor is adopted; at the later stage, fermented grains are fed into a Luzhou liquor pit and a production technology of the Luzhou liquor is adopted; the quality of the obtained Baijiu has the characteristics of mellow fragrance and elegance, mild liquor body, sweetness and tasty mouth feel endowed by traditional Xiaoqu liquor, as well as the characteristics of pit flavor and fermented grain flavor; in addition, compared with Xiaoqu Fen-flavor liquor brewed according to a traditional technology, the Baijiu prepared by the method has the advantage that the content of aroma and flavor-producing substances is obviously increased. According to the production method of the Baijiu, disclosed by the invention, the Xiaoqu Fen-flavor liquor distillers' grains are reused, so that grain consumption can be significantly reduced; besides, the production method has a broad application prospect.
Description
technical field [0001] The invention relates to a method for producing liquor by using discarded grains of Xiaoqu Qingxiang liquor, and belongs to the technical field of liquor brewing. Background technique [0002] Sichuan solid-state method Xiaoqu Fen-flavor Baijiu, Daqu Fen-flavor, and Bran-flavour Fen-flavor together constitute the three major types of Fen-flavor liquor. Short, high alcohol yield, the wine body is colorless and transparent, mellow and elegant, sweet and refreshing, pure and pleasant. This wine is an excellent base wine for the production of traditional nourishing wine and health wine. At the same time, it can also be used to blend new flavor liquors with different aromas and grades. [0003] With the improvement of social living standards, consumers' tastes are also evolving, and some original fragrance models have begun to fade away, from the past focusing on fragrance to focusing on taste, requiring emphasis on hygiene, health, mellowness and comfort ...
