1. Why do wines made with different brewing materials have different taste, flavor and personality?
The wine made from cereal crops and potatoes has a certain grain flavor. Like sweet potato wine, sweet potato flavor is heavy; corn wine has the sweet taste of corn, the taste is very strong. Sorghum has less egg white, less fat and a small amount of tannin, which is the main source of aromatic substances, so the taste of the wine is very fragrant. In all the brewing materials, the aroma of sorghum wine is very different. The production of Baijiu is a fundamental material. The flavor of Baijiu is partly distributed by the quality of the material.
2. why are different wineries taste different?
There are Daqu, Xiaoqu, bran koji and Chinese herbal liquor starter, and bone is the bone of wine. The liquor flavor determines the flavor and characteristics of Baijiu. Why is this so? Different koji have different enzymes, and the aroma substances produced in the fermentation process are also different.
3. what is the reason why the fermentation temperature and health will affect the flavor of Baijiu?
The fermentation temperature is high or the fermentation time is long, the ester and alcohol content are large, the taste is strong, the fermentation temperature is low, the time is short, the taste is indifferent. In the process of fermentation, the hygiene is not good, and the invasion of mixed bacteria also affects the quality of Baijiu. For example, wine smells bad and tastes bitter due to bacteria, or produces glyceraldehyde and tears. The excessive alcohol content of liquor will also affect the flavor of Baijiu baijiu. Too much yeast and yeast or too high fermentation temperature will make the Baijiu bitter.
4. why does fermentation affect the taste of Baijiu what is it?
Solid, semi-solid, liquid and raw material fermentation is a common process of bulk Baijiu fermentation. Different grains have different wine making processes, and the wine produced by different processes has different taste, and each has its own characteristics and advantages. Generally speaking, the aroma and fullness of solid liquor are better. Correspondingly, the foreign flavor will be heavier and less, while the semi-solid and liquid liquor taste is relatively fresh. The practical brewing technology can combine raw material and solid-liquid to make wine, and combine the advantages of various fermentation processes to produce good wine.
