Usually, wine has no shelf life, but is calculated according to the drinking period, that is, the best drinking time of red wine. After the drinking period, it means that red wine has begun to deteriorate slowly. Expired wine must be drunk in time after opening the lid, otherwise it will volatilize some substances and change its taste and lose its original flavor.
Matters needing attention in red wine storage
1, lighting: wine should be placed in a cool and dark place, and strong light irradiation should be avoided. Fluorescent lamps and the like must not be used, which may cause problems such as oxidation or light taste of wine.
2. Temperature: It is very important to keep the wine at a constant temperature for a long time. Excessive temperature fluctuation will do great harm to the wine, neither too cold nor too hot. The ideal temperature is between 1 1 to 15 degrees Celsius. Too high temperature will accelerate the ripening of the wine, and the cork will easily dry, which is not conducive to the storage of the wine.
3. Humidity: Humidity is also very important for long-term storage of wine. Generally, it is kept between 65% and 70%, and if possible, the storage room is best facing north.
4. Vibration: Find a quiet corner to store wine. Don't take it out from time to time to enjoy or wipe it. The last thing wine needs is shaking and light stimulation.
5. Smell: Keep the wine in a clean place without peculiar smell, so as to prevent the peculiar smell from seeping into the wine and causing the wine to deteriorate.
