How to judge whether red wine has gone bad How to judge whether red wine has gone bad

Nowadays, more and more people know how to drink red wine. It is not surprising that everyone has their own collection of red wine at home. However, red wine is easy to deteriorate and change its taste if it is not stored professionally. So how do we judge whether the red wine has deteriorated?

How to tell if red wine has gone bad

1. Judging whether red wine has gone bad by looking at it

Is the color of the red wine clear when poured into the wine glass? If it is turbid or even has snowflakes on the surface, then the red wine has gone bad. Of course, the sediment in the red wine is normal, which is related to the year the wine has been stored. It is a normal combination of pigments and tannins, and it does not mean it has gone bad.

2. Determine whether the red wine has gone bad by smelling it

First of all, you can detect whether the red wine has gone bad by smelling the cork before opening the bottle. If the cork has a rotten smell, the red wine has gone bad. If the rotten smell persists after the red wine is poured into the wine glass, it means that the red wine can no longer be consumed. In addition to the rotten smell, there may also be a moldy smell or a sulfide smell. This kind of smell is more pungent and is significantly different from the normal smell of wine. It is not suitable for drinking this kind of wine.

3. Judging whether the red wine has gone bad by tasting it

If there are no problems with the first two steps, then you need to identify it based on the taste. If the wine tastes sour, it is because the wine has produced acetic acid due to deterioration, and such red wine is not suitable for drinking.
