1, check the logo on the bottle. For example, solid liquor should be fermented from various grains. But we should also keep our eyes open to prevent unscrupulous manufacturers from shoddy. If the bottle says solid liquor, it can be determined that it is blended liquor.
2. Smell this wine. If there is no mark on the bottle, there are other ways to use it: smell, smell whether the wine has a faint fragrance or the taste of food. If the smell is choking, it is recommended not to buy it. Rub it back and forth with your hands, pour the wine on the clean palm and rub it back and forth. What smells good after kneading is good wine, and what smells choking is inferior wine.
3. Check the execution standard mark. See if the standard label is GB/T20822 or GB/T2082 1.
4. Check the product standard number.
5. Check the production license.
