Influence of Different Pit Bottom Materials on the Production of Jiangxiang Baijiu
The traditional production process of Jiangxiang Baijiu uses mud-bottom stone pit as the fermentation equipment,in which the pit bottom is laid with red sand mud,and the pit walls are made of red sandstones from the Chishui River,which has high silicon content,strong acid and corrosion resistance,and no water leakage.However,the direct contact between the fermented grains and the pit mud often results in a mud taste of the crude li-quor,which is not favorable.In this study,red sandstone and dried bamboo were laid at the bottom of the pits,respectively,and the influence of the three kinds of pit bottom materials on Jiangxiang Baijiu was studied.It was found that the red-sandstone pit bottom could not only reduce the mud taste of the crude liquor,but also increase the contents of total acids and total esters of the crude liquor,and the cleanliness and complex aroma of the liquor body were effectively improved.In conclusion,red sandstones can be used to reform the bottom of traditional Jiangxiang Baijiu fermentation pits.
