Teach you how to identify spoiled wine

Wine is known as a living drink, and its taste and nutritional value are excellent. However, grapes can also go bad, and their nutritional value and taste will change significantly. So how can we identify spoiled wine?

How to identify spoiled wine

1. Color change

The color of wine will change significantly after it goes bad, especially after the wine is oxidized, it will lose its original color, and the original bright red will be transformed into brick red or brown red, and the luster will be particularly dark, making people feel that it is particularly dull at first glance.

2. Taste changes

The taste of wine will change significantly after it goes bad. When it is stored in a high temperature environment, the taste change will be most obvious. It will have a jam smell and the cork of the wine will be pushed up. At this time, the grapes have obviously deteriorated and are not suitable for drinking.

3. Taste changes

The taste of wine will change significantly after it goes bad. People can identify whether it has gone bad by taking a small sip. If the wine still tastes vinegar or is lifeless, it means that the wine has been oxidized and deteriorated. If the wine has bubbles or carbonic acid when tasting, it means that it has undergone secondary fermentation after bottling, which is also a common manifestation of wine deterioration.

4. Cork changes

After the grapes go bad, the cork used to seal the bottle mouth will also undergo some changes. The most common change is that it will bulge out from the bottle mouth. At this time, the taste and mouthfeel of the wine in the bottle will change significantly, and the nutrients will be lost in large quantities, making it unsuitable to open and drink.
