Now there are several ways to learn liquor blending. First, the whole process from fermentation principle to liquor packaging will be involved in professional colleges. Second, training institutions, mainly wine-making associations in various provinces, will also hold food industry associations on a regular basis, which are generally found in provinces that make more wine. Third, the winery looks for a master. If there is an opportunity to communicate, I am doing liquor blending technology in the winery.
