In fact, different ways of storage, can be stored for different times.
1. Refrigerator storage can be about a week
If you open a bottle of red wine and don't finish it in time, you can put the cork back in the bottle and store it in the refrigerator for about a week. If you want to prevent odors in the refrigerator from affecting the flavor of the wine, you can add a layer of plastic to the outside of the bottle, though the refrigerator's freezing temperature will more or less affect the flavor of the wine.
2. Room temperature conditions can be stored for about 1-3 days
Generally the alcohol is relatively low and not yet finished, and there is a plug back to the cork can be saved for 1 day. If it is a high alcohol red wine can be saved for about three days.
3. The air-exhaust method can be saved for 2-3 days
If you use a vacuum pump to pump out the air inside the bottle, or use inert gas to fill in the way to prevent the red wine from being oxidized and deterioration occurs, the red wine in this case can be preserved for two to three days or so, but it must not be more than a week.
