Abstract

The invention relates to the technical field of liquor making, in particular to a Maotai-flavor Daqu liquor stable pile fermentation process. The process includes steps: (1) decontamination and grinding treatment of grains for liquor making; (2) adding of high-temperature measured water for wetting the grains, and steaming; (3) discharging from a steamer, water measuring, spreading for cooling, starter adding and tail liquor adding; (4) pile fermentation; (5) fermentation in pits; (6) outputting from the pits, steaming and liquor outputting. In the step (4) of pile fermentation, isolators arearranged between the bottoms of piled materials and the ground of a piled material site to realize regular ventilation in pile fermentation. By the pile fermentation process, fermentation time is shortened, a stable high-temperature fermentation state can be achieved in pile fermentation, and the total liquor yield and the high-quality liquor yield are greatly increased.

Description

technical field [0001] The invention relates to the technical field of brewing, in particular to a stable accumulation fermentation process for Maotai-flavored Daqu liquor. Background technique [0002] Maotai-flavored wine has a prominent sauce aroma, elegant and delicate, mellow and full-bodied flavor, which is inseparable from accumulation fermentation. In the prior art, there are very few technical studies on the accumulation fermentation of wine, mainly on the changes in the number of yeasts in the accumulation fermentation, etc., for example, "Review of Moutai Science and Technology Pilot Project" records: the change of the number of yeasts in the accumulation fermentation was studied; In the article "Talking about Daqu Maotai-flavor Liquor's Coarse Sand Technology" in "Brewing Technology", it only studies the amount of yeast that can reach from when the coarse sand is piled up to when it is piled up and fermented into the cellar; Originated from management": Studying...
