The quality of wine is mainly related to two points: the quality of the grapes and the brewing process. To identify the quality of white wine, professionals have many methods. They mainly make professional judgments through vision, smell, taste, etc. However, as ordinary consumers naturally will not use such professional methods, they must use the brand awareness and reputation of the product. Judging by degree, generally the product quality of companies with good brands will naturally have higher credibility. In fact, the most important thing for ordinary consumers is the feeling after taking a sip. If they feel comfortable in the mouth, not too sour and not too astringent, like the aroma, comfortable to swallow, and taste good, then it means that the wine is still good.
