| 摘要： |
浓香型白酒生产中，入窖糟醅正常升温规律为“前缓、中挺、后缓落”。但是在母糟活力差、环境气温低等条件下，会引起入窖糟醅无法正常升温。具体表现为升温幅度小、顶温不高、升温慢或不升温现象。因主发酵期糟醅未能正常升温，糟醅中的淀粉得不到充分利用，直接影响排次酒的产量和质量。针对这一现象我们借鉴酱香的堆积升温的原理，将小部分入窖糟醅进行堆积发酵，自然网罗微生物，待堆积顶温达到要求时，与入窖糟醅进行拌和后入窖发酵，目的是同酱香堆积一样起到“二次制曲”的作用。 |

| 英文摘要： |
In the production of Nongxiang Baijiu, the normal temperature rising rule of pit-entry fermenting grains is known as “slow rise in the prior stage, stable in the medium stage, and slow drop in the late stage”. However, under the conditions of poor maternal grains activity and low environmental temperature, it’s difficult to rise temperature normally for fermenting grains, and some problems might occur including unobvious temperature rise, low temperature at the top of pit, slow temperature rising rate, and sometimes even no temperature rise. If fermenting grains fail in normal temperature rise, the starch in fermenting grains will not be fully utilized and will further influence the yield and the quality of the produced liquor directly. In the experiments, we drew on the operating principles in stacking fermentation of Jiangxiang Baijiu and used a small amount of pit-entry fermenting grains for stacking fermentation. Then as the stacking temperature met the requirements, we added the fermenting grains in pit and mixed them for subsequent fermentation. The purpose of the operation was to achieve the effects similar to the second Daqu-making of Jiangxiang Baijiu. |
