No matter what preservation method you use, remember that wine is a perishable product. While proper techniques can extend the life of an opened bottle, the wine will typically last 3–5 days for whites and rosés, and up to a week or more for reds. Very fine wines may last longer, but for optimal enjoyment, it’s best to drink them sooner rather than later.
By paying attention to the factors that affect wine quality after opening, you can enjoy your wine at its best even days after the cork has been pulled. Proper preservation techniques are key to ensuring that every glass is as enjoyable as the first.
