2. Different aging time: Cognac will be divided into different grades according to different aging time. According to relevant laws and regulations, the minimum aging time of high-quality blended (VS) aged (VSOP) brandy should be no less than 4.5 years, and the minimum aging time of special brewing (XO) should be more than 6.5 years.
3. Observe carefully with your eyes: all kinds of famous wines have their perfect brightness, and suspended particles will not affect the quality of wine. Some tiny precipitates in high-quality wine are generally harmless, but the turbidity of wine (filaments or fog in wine) indicates that the wine has gone bad.
4. Smell: The aroma of the wine in the glass tells the user the kind and quality of the wine. In order to distinguish the aroma of wine, the wine rotates gently in the cup. Newly brewed wine has the unique aroma of fresh fruit, while high-quality wine has rich and varied smells.
