"The older the wine is, the more fragrant it will be." in general, it is true that many fine wines have to undergo a long period of precipitation to produce their unique flavor. But for red wine, it is not so, so does the wine have a shelf life? How to identify whether the wine is deteriorated?
Does wine have a shelf life
Wine has a shelf life.
In China, when the alcohol content exceeds 20%, the shelf life can not be clearly marked, while the alcohol content of wine is generally between 8% and 15%, which belongs to low alcohol wine. Therefore, the wine in China has a clear shelf life.
Can I drink wine that has passed the shelf life?
In fact, wine that has passed its shelf life can still be drunk. Foreign wine trademarks do not indicate the shelf life, there is no concept of shelf life. According to the understanding of Chinese people, wine within the shelf life should be clear, without turbidity, without precipitation, and the taste effect should be the best.
How to tell if a wine has gone bad
Look at the color: generally, there are three kinds of wine: purple, red and brown. The deeper the color is, the longer the wine is stored, the better you can drink it. However, the color of expired wine is orange, with the edge tone as the main observation point. This color of wine is not recommended to drink.
See transparency: the more common wine in life is filtered, therefore, the transparency is better, and the deteriorated wine will produce some impurities, the transparency is not high, but pay attention to the wine without filtration can not be identified by this method.
Look at impurities: the wine on the market after filtration, generally there will be no impurities, even if there are grape seeds and grape skin, and expired wine will breed a lot of fungi, white bacteria will appear on the surface of the wine, and there are flocculent impurities in the wine.
Taste: a good wine has a strong aroma, fruit flavor, red wine and astringent taste, while the deteriorated wine has a sour smell, and the taste is light after entering, and the wine flavor is almost No.
