The data in Table 3 showed that alanine, arginine, aspartic acid, glutamic acid, glycine, leucine, and proline were the major components among all the amino acids in Chinese rice wine samples. The proportion of bitter tasting amino acids is generally the same as that of sweet tasting amino acids. After 20 days of fermentation, bitter tasting amino acids and sweet tasting amino acids constitutedmore than 36% and 38% of the total amino acids, respectively.
