The research center of traditional brewing food of Jiangnan University evaluated the flavor of Huangjiu in different production areas. The results showed that Shanghai Huangjiu and Jiangsu Huangjiu have stronger rice flavor, and the northern Aged Wine has stronger sweet, astringent, bitter and burnt flavor. And compared with them, Shaoxing Huangjiu has stronger flavor of fruits, wheat koji, soy sauce and mushrooms.

According to the sugar content, Shaoxing Huangjiu can be divided into dry Huangjiu, semi-dry Huangjiu, semi-sweet Huangjiu and sweet Huangjiu. The dry Huangjiu is fresh, and has strong flavor of wheat koji, nuts and acetic acid, with a little bitter and a slight aftertaste. Semi-dry Huangjiu is mellow, fresh and sweet, and has strong flavor of fruits, honey and yeast. The taste of semi-sweet Huangjiu is balanced. It is sweet and has strong flavor of smoke and caramel. Sweet Huangjiu is sweet, fresh and mellow, and has a strong flavor of soy sauce and leather.
