Usually, the color of wine is ruby red, or light gold, pink and other clear natural wine colors. After the wine body goes bad, it will have a turbid feeling. If the color is unnatural, it will be suspected of blending.

There will be a groove at the bottom of an ordinary imported wine bottle, which is used to store the wine dregs precipitated when the wine stands upright.
