The analysis of the catalyzed aged wine by physico - chemical index

The newly-produced and uneatalyzed wine, the naturally-aged wine of three years and the catalyzed wine stored for six months are analyzed by physico-chemical index. The result shows the physico-chemical index of the catalyzed chenggang wine is greatly increased, especially the content of the volatile ester, compared with the newly - produced wine. All index has reached the best-quality wine. The analysis of the 100 tons sample for four times reveals that the degree of the catalyzed wine stored for six months decreases by 5.3% and the content of ester increases by 34.3%.
