2. Brand choice. First of all, we should choose well-known enterprises and brands. Generally speaking, well-known brand wines have better quality assurance.
3. Look at the packaging. In order to prevent the photochemical reaction of wine, most wines are packed in green glass bottles. Therefore, attention should be paid to the color of the bottle label and the contents of sugar, acid and alcohol marked when purchasing, and the variety of wine should be defined. Generally, the main color of the bottle label of white wine is golden yellow, while red wine is mostly red. Alcohol below 9 degrees is usually staple goods and ordinary wine. In addition, there is no shelf life for wine, and proper precipitation is allowed by quality standards. The key is to seal the bottle mouth well and prevent alcohol from volatilizing, so that the flavor can remain unchanged.
4. Read the wine label. Reading wine labels is the most direct way to know the background information and characteristics of each bottle of wine before purchasing. The wine label is the identity card of the wine. According to the relevant regulations of the state, the product name, ingredient list, net content, pure juice content, alcohol content, sugar content, factory name, address, production date, shelf life, product standard code and other contents must be indicated on the wine bottle label. If the label is incomplete or does not indicate the factory date, factory name and address, it is a fake and inferior product. To drink good wine, you should buy products that implement national standards, and products that implement enterprise standards should be carefully selected. With regard to the production date of wine, many people think that the longer the better, but in fact, not every bottle of wine can be collected. Most wines have a life span of only five years, and then they lose their essence, just like the beauty is dying. Therefore, wine also needs to be drunk at the right time to taste its peak flavor. Even in those wines that can be collected, we should know how to collect them well at appropriate humidity and temperature. Most consumers buy dry red wine for drinking, so they should choose wine with a shorter filling date when buying, which is fresher.
5. Appearance. The naked eye observation is helpful to understand the quality of each bottle of wine before purchasing. Hold the bottle high to the light source, and observe its color from the appearance. Dry red wine should be clear and transparent (dark wine can be opaque), shiny, and its color should be consistent with the name of the wine, with natural and pleasing color; However, poor quality wines are either dull or bright, and have obvious artificial color. It is normal to have a small amount of sediment in bottled dry red wine. The sediment is some pigments and some compounds, which have no effect on the flavor and taste of the wine. However, if the wine is cloudy and dull, it is inferior.
6. Aroma. Wine is a fermented product, and its aroma should be fruity, fermented and aged, which should be balanced, coordinated and integrated, elegant and pleasant, while poor quality wine does not have the above characteristics, or has a prominent and violent fruit aroma (plus essence), or an outstanding alcohol flavor, or has other peculiar smells.
7. Taste. Any good wine should be comfortable and pleasant in taste, with delicate and soft aromas, full-bodied and complete, layered and structured, and a long aftertaste; And the poor quality wine, or have a peculiar smell, or extraordinary fragrance, or thin body without layering, or no aftertaste.
