Why does drinking wine make your mouth black

It is normal for your lips to turn black after drinking wine. If your lips turn black more seriously, it may be caused by drinking too much.

Wine is mainly made from fermented grape juice, which contains a large amount of pigments, as well as tannins, anthocyanins and other ingredients. During the brewing process of red wine, the color depends on the soaking time of the grape skins. Generally, red wine is easy to color at the right time. The color of the wine is adjusted by controlling the soaking time, such as red wine and rosé wine. It is usually normal for the lips to turn black after drinking alcohol, because they contain some pigments. The human tongue, teeth and lips have a layer of mucous membrane tissue, which easily absorbs pigments. After drinking alcohol, the mucous membrane of the lips easily absorbs pigments. If you drink too much, the accumulation of pigments will also increase, which will cause the lips to turn black. It is also related to one's own physical constitution. Everyone has different physical constitutions, so the color of the lips will be different after drinking.

Drinking wine can not only beautify your skin, but also promote physical and mental health. Drinking a glass of wine after staying up late to work overtime can keep the body comfortable and cheerful. Avoid drinking too much wine because it contains some alcohol. If you take too much, the brain nerves will be inhibited, which can easily cause memory loss in the long run.
