The precise answer to the question “How long does red wine last once opened?” depends to a large extent on storage conditions — re-cork the wine as soon as finished drinking.
Refrigerating an opened bottle of red wine will help keep it fresher; take the red wine out of the fridge about an hour before serving to bring back to room temperature.
If a cork or stopper is not available for the opened bottle of red wine, cover the opening with plastic wrap and place a rubber band around the bottle neck to seal plastic tightly.
In general, opened bottles of full-bodied red wines such as cabernet sauvignon, merlot and syrah will maintain their flavor longer than lighter varieties such as pinot noir.
Leftover red wine may be frozen and used later for cooking — freeze the red wine in airtight containers or pour wine into ice cube trays; once the red wine is frozen, transfer cubes to a heavy-duty freezer bag.
How long does red wine last in the freezer for safety purposes? The freezer time shown is for best quality only —foods kept constantly frozen at 0° F will keep safe indefinitely.
How to tell if an opened bottle of red wine is bad? The best way is to smell and look at the red wine: red wine that has gone bad often develops an off smell and a brownish appearance.
