应用新技术改造窖池提高原酒质量

利用从洋河老窖泥中分离出的优良菌株作为菌种，进行优化、扩大培养，制作人工老窖泥，进行窖池改造。改造后的窖池与未改造的窖池比较，结果表明，窖泥感官和理化指标及产酒产量、质量、出酒率、优级酒率得到明显提高；窖池产酒的主体香味成分己酸乙酯和乳酸乙酯含量提高较大；窖池的改造给公司带来了可观的经济效益和社会效益。（孙悟）

Reconstruction of Pits Entrance by New Techniques to Improve the Quality of Brut Liquor

The quality microbial strains separated from Yanghe aged pit mud were optimized for expanding culture to produce manmade aged pit mud for the reconstruction of pits. Through the comparison between the reconstructed pit and the original pit, it was easily concluded that evident improvement had been achieved for the reconstructed pit in pit mud phy- siochemical index, liquor output, liquor quality, liquor yield, and quality liquor output rate etc. Especially, ethyl caproate content and ethyl lactate content in liquor produced in reconstructed pit increased greatly. The reconstruction of the pits brought considerable economic benefits and social benefits to the enterprise. (Tran. by YUE Yang)
