Changyu brandy is divided into Samsung brandy, vs brandy, vo brandy, vsop brandy and xo brandy. First of all, it depends on which grade your brandy is. If it's not xo brandy, let alone. It's worthless, because the grade of brandy is directly related to the texture of the wine itself when it leaves the factory. Even xo is not, indicating that its texture is not of high standard, let alone suitable for storage. It should be added here that Changyu brandy still lags far behind French cognac. If it is Changyu xo brandy, it is of high quality in Changyu products, but 20 years is too short. If you find a personal lover of brandy, you may buy it. The price refers to the xo brandy of Changyu now. Now the price is around 200, plus 50%, it is estimated to be 300. I don't think anyone will want to go any higher. Changyu will definitely not buy back brandy, because Changyu has many samples of brandy that are 20 to 50 years old. A few years ago, a comrade in Qingdao found a bottle of Changyu 1949 brandy when decorating a house from his hometown. As a result, Changyu Company repurchased it, and the repurchase price seems to be 5000 yuan. If you go to Changyu Museum, you can find older brandy.
