High tannin red wines can be keptfor up to7 days.

If you're opening a new bottle of Cabernet Sauvignon red wine just to have a glass or two, don't throw away the cork. Corks have been an important part of the red winemaking process for centuries. The cork material is dense enough to keep the wine fresh without completely insulating it from air. Having a small amount of oxygen in the bottle allows the wine to continue to ferment, while too much oxygen can cause the wine to become acidic and unpleasant to the palate. As soon as you've finished pouring, seal the bottle with a cork to prevent more oxygen from entering the wine.

Keeping your uncorked wine in the refrigerator reduces the wine's exposure to other factors that can cause it to spoil, such as heat and light. Most red and white wines will stay good for two to five days as long as they are kept in the refrigerator. Sparkling wines, however, have a shelf life of only one to three days after opening the cap, and some natural sparkling wines spoil within a day of opening the cap. High-tannin red wines sold in supermarkets usually have the longest shelf life, up to seven days, after opening the cap.
