Opened wine should be corked back and the bottle placed in the refrigerator, horizontally.
1. White wines can be kept in the refrigerator for up to 1 week after opening.
2. Red wines can usually be kept in the refrigerator for 2-3 weeks after opening.
The bottle can be kept for about a week by first pumping the air out of the bottle and then corking it. But it's more economical to replace leftover wine in smaller bottles that don't hold air, and it will keep for another 24 hours.
But open bottles of wine should be consumed as soon as possible, because the longer they are kept, the faster their flavor will dissipate. In addition to where you keep it, the way you place the bottle should also be taken care of. Wine must be placed horizontally, preferably with the mouth of the bottle slightly tilted downward, which will not only help the dregs of the wine to settle, but also the cork can be moisturized by the wine to maintain a certain degree of humidity, and the mouth of the bottle will be tightly plugged by the cork.
Expanded Information:
It is best to store wine at a constant temperature and short-term temperature fluctuations need to be avoided as much as possible. Usually the higher the temperature, the faster the wine will mature; at lower temperatures, the wine will grow more slowly.
Of course, the rate of ripening varies according to the grape variety and winemaking method used. Generally speaking, the optimal storage temperatures required for different wines are as follows:
1, semi-sweet, sweet red wine 14-16 ℃
2, dry red wine 16-22 ℃
3, semi-dry red wine 16-18 ℃
