How to distinguish the authenticity of red wine

The authenticity of red wine can be distinguished based on its color, liquid, cork, taste, etc. Generally speaking, real red wine will show uniform water stains on paper, while fake red wine will have darker colors in the middle and lighter colors on the outer circle.

It is best to store red wine in a wine cellar, either in a basement or a wine cabinet, and ensure a cool and ventilated environment.

Avoid placing red wine in direct sunlight and high temperature. Strong sunlight and high temperature will accelerate the aging of red wine, causing it to deteriorate.

What causes red wine to become sour?

The sourness of red wine may be due to the fact that the raw materials themselves contain acidic components such as citric acid, malic acid and tartaric acid. However, it may also be because the red wine is constantly fermented during the brewing process, and the acidic substances such as succinic acid, lactic acid, acid, acetic acid, etc. produced by it will also make the taste of red wine sour.

The sourness of red wine may be due to the acidic components in the raw materials of red wine. The main raw material of red wine is grapes, which contain a large amount of acidic components such as citric acid, malic acid and tartaric acid.

During the process of brewing red wine, the wine will produce acidic substances such as succinic acid, lactic acid, and acetic acid through continuous fermentation, and these acidic substances can make the taste of red wine fresh.

Like metal, red wine is easily oxidized when there is too much oxygen. Oxidation is a common defect in red wine. Oxidized red wine not only tastes sour, but also changes its color from bright red to reddish or brownish red.
