If you have ever wondered how long wine remains drinkable after you open it, then you will be happy to hear that Food & Wine magazine http://foodandwine.com has offered some guidance on this topic. These are general “Rules of Thumb”; it is always best to rely on your own common sense to determine if a wine is still good to drink. 

According to F&W, wine generally stays drinkable for 1-7 days after opening, depending on the type and how it is stored. Sparkling wine will generally stay 1-3 days when refrigerated. To keep the bubbles, consider buying a stopper designed for sparkling wine. For light-bodied whites/Rosé, count on 2-3 days (refrigerated). Full-bodied whites can last 3-5 days (refrigerated). Red wine is good for 3-5 days (refrigerated). Some important constants to keep in mind when storing any open bottle of wine are to recork and refrigerate it. Using a vacuum stopper to minimize air contact is also a good idea. Boxed wines can last 3-4 weeks in the fridge because they are in a bladder inside the box that collapses when you draw wine out, and that keeps air contact with the wine low. 

If your wine goes bad, you will know because it tastes or smells like vinegar, stale, or just plain unpleasant. When this happens, don’t drink it and throw it out. You now have a good excuse to have another glass when you open the bottle. Waste not Want not.
