High-quality wine is rich in alcohols, esters, phenols, aldehydes, organic acids and other compounds, so it has a typical mellow, floral, fruity or variety fragrance, pure, rich and pleasant. On the contrary, the smell of inferior blended wine is generally pungent and blunt, or mostly alcohol and essence.

Some requirements for good wine:

1. Variety characteristics: Whether a wine has typical variety characteristics is very important for judging its quality. For example, PinotNoir wine, if it only has a strong oak aroma and does not reflect the typical red fruit aroma of black Pi Nuo, then its variety characteristics are not obvious and it is not a good wine.

2. Balance: Balance means that all the elements of wine-fruit aroma, alcohol content, tannin, acid, sugar, body and aftertaste-complement each other, and none of them is too abrupt. For example, if a wine will cause a sharp burning sensation in your throat, it means that its alcohol content is too high and there is not enough fruit aroma, flavor and body to coordinate with it. If a wine has a strong oak flavor, it also shows that its balance is not enough, and there is not enough fruit flavor to match the oak flavor.

3. Strength: Strength is about aroma and taste. The richness of wine aroma and flavor is mainly determined by the variety itself and the brewing method. So what kind of wine has the best richness? If you put a glass of wine on your chest, you can still smell its aroma, which means it has excellent aroma. If a wine can bring a variety of flavors to people's mouths, it means that its flavor is better.

4. Complexity: Complexity is different from richness. A full-bodied wine may have only one or two simple aromas or flavors, and such a wine cannot be called "complex". Complex wines make you think. Its aroma is very active and layered, which will change with time. In addition, its flavor is also very diverse. The antonym of complexity is simple, plain and boring.

5.ALongFinish: Whether the aftertaste is long or not is one of the criteria for judging the quality of wine. The aftertaste of many "big wines" can last for 30 seconds. But for ordinary wine, if its aftertaste lasts 15 seconds, it is enough to show that its aftertaste length is excellent.

6. EmotionalReaction: If a wine can make you feel charming, make you happy and make you want to have another drink, it means that it has successfully stimulated your emotional reaction and won your "heart".

Finally, when judging the quality of a wine professionally, we should try to avoid being influenced by personal taste bud preference and brand effect, and start with objective factors such as its variety characteristics, balance and complexity.
