Brandy has a high alcohol content, and the shelf life of high-quality brandy is as high as 10 year. Brandy is a strong distilled liquor, and its brewing raw materials are grapes and other fruits. When storing brandy, it is necessary to avoid strong light, and the temperature and humidity should be appropriate to avoid the instability of the wine body caused by vibration and shaking. Well-sealed whisky or cognac can be preserved for several years as long as it is stored properly, otherwise it will taste much worse, although it will not go bad.
