Why spend the same amount of money, some people buy pure grain wine with good taste, and some people buy inferior alcoholic wine that hurts the body? How to choose when buying liquor? Learn these tricks, and you won't be afraid that you won't be able to choose a good sauce wine! 
1. Look. After pouring the liquor into the glass, gently shake the glass to see how fast the liquor flows, which is slower than the speed of water. The reason is that baijiu contains a variety of trace elements, which will directly affect the consistency and richness of baijiu.
Second, the hand. The liquor can feel silky and astringent between the fingers, and it is similar to the feeling of hot chocolate, because there is a layer of ester film in the wine molecule, and the ester substances and water molecules rich in esters are formed by long-term intermingling and penetration in the wine, so the wine body will have a silky and astringent feeling.
3. Overflow. Good wine has a complex formed by healthy metal factors such as selenium, zinc, iron, etc., which can make the structure of the wine full of tension, and after pouring it into a clean wine glass, it can overflow the wine glass.
Fourth, smell. Smelling is one of the most important steps in wine tasting. Through "smelling", you can know the raw materials used in the brewing of liquor, the quality of the fermentation process, and even the degree of aging of the liquor. High-quality liquor can exude natural aromas such as dregs, grain, koji, floral, fruity, grassy, aged and other natural aromas, and the taste is harmonious and unified.
5. Taste. When tasting, be careful to leave the liquor in your mouth for a few seconds before swallowing. If the taste is soft and delicate and has a long aftertaste, it is a high-quality liquor.
