How long can an open bottle of red wine last?
On One Hand: About Three DaysRed wine lasts for about three days after opening. Once a bottle is opened, oxygen comes in contact with the wine. This process oxidizes the wine and will change the taste of the wine. Wine will also start to smell different and will usually become undrinkable quickly.On the Other: Lengthening FreshnessThere are several ways that wine can be preserved further than three days after opening. Red wine should be refrigerated after opening. This delays the oxidation process. Wine vacuums are devices that remove part of the air from inside a bottle and tightly seal the bottle. This device may extend the freshness of the wine a few additional days as well.Bottom LineRed wine should be drunk as soon as possible. With every passing day, the quality of the wine becomes compromised, even using a vacuum pump and refrigerating the wine. Unlike bottled wines, boxed wines can be opened and consumed over about a month period.
