Because red wine contains peel residue, phenolic substances such as tannins and pigments are dissolved in the wine after fermentation. In addition to promoting blood circulation, these substances can remove greasiness and prevent blood vessels from breaking down. Increased rates of sclerosis and cholesterol.

White wine does not have these health benefits because it is fermented with clarified grape juice. But white wine may prevent heart disease.

There is no big difference in nature between red wine and white wine. White wine is fermented with clarified grape juice, while red wine is made with skin residues (including peels, seeds and fruit stems) mixed with grape juice. Fermented, the source of the red color is the pigment in the peel.

Red wine storage:

Cork stopper:

Cork stopper has low density, good elasticity and strong scalability , impermeable, anti-corruption, anti-decomposition, anti-deterioration and other characteristics, which can keep the quality of wine unchanged for many years. Usually, the length of cork used in general-grade wine is about 3.5 cm to 5 cm, and the length of cork used in relatively high-quality wine is more than 5 cm.

Generally, high-quality wines use longer corks, but wines using long corks do not guarantee that they are high-quality wines.

Room temperature:

We often hear that a certain wine is best "drinked at room temperature". What is room temperature? In fact, room temperature usually refers to the temperature in the place of origin, not the room temperature in China. For French wine, room temperature usually refers to around 16 to 18 degrees Celsius.

For China, which has a vast territory, except for the cold winter, most of this temperature needs to be refrigerated to achieve this temperature. Never leave wine at normal temperature, as it is taken for granted that it is "room temperature".
