Why should red wine glass bottle be put upside down?

Red wine must be put upside down when it is stored, because red wine needs to be kept wet when it is sealed with a cork to prevent a large amount of dry air from entering the bottle, which will lead to the oxidation and deterioration of red wine. At the same time, the aroma of the cork and phenolic substances can be dissolved into the liquor to generate substances beneficial to human health.

temperature

The temperature of wine storage is very important. If it is too cold, wine will grow slowly. It will stay in the freezing state and will not continue to evolve, which will lose the significance of wine storage. It is too hot, and the wine matures too fast. It is not rich and delicate enough, which makes the red wine excessively oxidized or even deteriorated, because the delicate and complex wine taste needs to be developed for a long time. The most important thing is that the temperature should be stable, preferably between 11 ℃ and 14 ℃. Temperature fluctuation is more harmful than slightly higher or lower temperature.

Avoid light

It is best to keep away from light when storing, because light is easy to cause deterioration of the wine, especially fluorescent lights and neon lights are easy to accelerate the oxidation of the wine, giving off a strong and unpleasant smell. The best place to store wine is to face north, and the doors and windows should be made of opaque materials.

improve air circulation

The storage space should be ventilated to prevent the musty smell. Wine, like a sponge, will suck the taste around into the bottle, so it should avoid putting onions, garlic and other heavy taste things together with wine.

Vibration

The damage of vibration to wine is purely physical. The change of red wine in bottle is a slow process. Vibration will accelerate the ripening of wine and make it rough. Therefore, try to avoid moving the wine around, or placing it in a place with frequent vibration, especially the old red wine. Because it is 30 to 40 years or longer to store a bottle of aged red wine, rather than just three to four weeks, it is best to keep it “asleep”.
