The main differences between red wine and white wine

1. According to the color of grapes, grape varieties can be divided into three categories: white varieties (white skin and white flesh), red varieties (red skin and white flesh) and dyed varieties (red skin and red flesh). White varieties are used to make white wine, dyed varieties can only make red wine, and red varieties can be used to make a variety of wines ranging from white to dark red.

2. White wine is made by fermenting white grape juice, and red wine is made by fermenting a mixture of grape juice (liquid part) and grape skin residue (solid part). The depth of its color is determined by the intensity of the impregnation of the liquid part into the solid part. The stronger the impregnation, the darker the color.

3. The solid part brings not only pigments to the wine, but also tannins, which are phenolic substances like pigments. The darker the color of the wine, the higher the content of phenolic substances composed of pigments and tannins.

Therefore, the main difference between red wine and white wine lies in the content and types of phenolic substances between them.

Benefits of red wine:

1. Red wine can inhibit the oxidation of low-density lipoprotein (LDL), increase high-density lipoprotein (HDL) in the blood, promote blood circulation, and prevent coronary heart disease;

2. Resveratrol in red wine has anti-cancer effects;

3. Red wine contains the antioxidant ingredient Flavonoids, which can fight cancer, anti-aging and prevent platelets from clotting into blood vessels.

4. Red wine is rich in phenolic compounds Procyanidols, which can prevent arteriosclerosis and maintain vascular permeability.

5. Red wine is rich in tannins, which can prevent tooth decay and radiation damage.

Wine storage:

1. The wine bottle must be placed diagonally, horizontally or upside down so that the wine can contact the cork to keep it moist;

2. The ideal wine storage temperature is between 10 and 16 degrees Celsius. The lower the temperature, the slower the maturity. The humidity is about 60% to 80%, but the wine label is prone to mold when the humidity exceeds 75%.

3. Constant temperature is more important than low temperature. Keep away from heat sources such as kitchens, water heaters, and stoves. A constant temperature of 5 to 10 degrees Celsius higher than the ideal temperature is far more ideal than a place with a large temperature difference between hot and cold. So if you don’t have ideal wine storage equipment and want to buy some wine to drink and taste slowly, you can wrap it with newspapers, nylon and other materials to reduce the impact of external temperature changes, then pack it in boxes and find the coolest place that is not affected by sunlight to store it;

4. Avoid damage from strong light, noise and vibration;

5. Avoid placing the wine together with odorous or unpleasant-smelling items such as gasoline, solvents, paint, and medicinal materials to prevent the wine from absorbing the odor.
