Method for producing Luzhou-flavor liquor

The invention discloses a method for producing Luzhou-flavor liquor. The method comprises the following steps: adding 90-95kg of grains and 20-25kg of hulls into each cubic meter of pit distiller grains, uniformly mixing, steaming liquor and metering water; then, adding a medium-temperature starter into the cooled distilled grains, uniformly mixing, and putting the distilled grains into a bio-reactor; sealing and fermenting the distilled grains in the bio-reactor for 35-50 days; circulating yellow water every 5-7 days after the main fermenting period is completed; taking out the distilled grains after fermentation is completed, turning over and distilling to obtain the Luzhou-flavor liquor. According to the method, the bio-reactor is adopted to replace a traditional pit to brew the Luzhou-flavor liquor; due to a small floor area, floor area is intensively used; the proportion of the contact area of fermented grains and pit mud in the bio-reactor to the volume of the bioreactor can be spontaneously adjusted; the yellow water circulation can be carried out by virtue of a water pump after the main fermentation period is completed, the mass of distilled grains at each layer in the bio-reactor approaches to accordance, and energy consumption is low.
