gelatin to assist clarification and deastringency, and performing post
fermentation; sampling, adjusting indexes, such as alcoholic strength, filtering by refined
filtration devices, such as a centrifuging device and an
ion exchanging device, continuously
ageing, changing a tank, and
ageing again for not less than 9 months; and finally, performing centrifugal ultra-
filtration to obtain a product. A making process provided by the invention is simple and feasible, the obtained
