北方大曲酱香酒云门陈酿高温堆积发酵工艺探讨

Research on the High Temperature Stacking Fermentation Technology Applied in the Production Process of North Maotai-flavor Daqu Yunmen Aging Liquor

随着大曲酱香白酒生产轮次的增加,含水量逐步增大,堆积糟醅疏松性差,采用堆积底部铺垫稻皮20cm以上,外接不锈钢通风管的方法,适当增加堆积糟醅堆底部含氧量,能有效提高堆积糟醅“大回酒”堆底和堆芯升温幅度,对提高“大回酒”出酒率和质量有一定作用。

The water content became higher gradually as the production cycles of Maotai-flavor Daqu Liquor were increased, and the loose characteristic of the stacked fermented grains was poor. The skins of rice were paved in the bottom of the fermented grains, and the thickness of the skins was higher than 20 centimeters. Stainless steel ventiducts were also equipped in order to appropriately improve the oxygen content. The temperature rise in both the bottom and center of the stacked fermented grains of Dahui liquor was increased effectively, which had a positive influence on improving the yield and quality of Dahui liquor.
