Seven. Maotai's base wine is divided into seven rounds. Based on its unique brewing technology and the characteristics of base liquor, Maotai's base liquor is divided into seven rounds. Maotai-flavor liquor is brewed by local waxy sorghum, with nine ripens and eight fermentations, and seven liquors are used to maximize the use of raw materials. Each of these seven rounds of base wine has a different style, corresponding to three typical wine bodies: maotai, mellow and cellar bottom. The method of taking wine by turns is conducive to extracting wine bodies with different styles and qualities, and also provides rich choices for subsequent blending. Blenders can carry out complex blending processes according to different rounds, different wine ages, different typical bodies and different alcohol degrees, so as to adjust the taste, aroma and quality of the wine, and finally blend Moutai with ever-changing tastes.
