Can You Still Drink Wine That’s Been Sitting Out?

Left a glass (or bottle) of wine out overnight? Don’t pour it out just yet. In most cases, yes, you can still drink wine that’s been sitting out for 24 hours—and it’s perfectly safe. The alcohol content and natural acidity act as preservatives, keeping harmful bacteria at bay.

That said, the real question isn’t about safety—it’s about taste. Wine exposed to air undergoes oxidation, which can dull its flavors and aromas. Within a day, lighter whites and delicate rosés are usually the first to lose their freshness, turning flat or slightly vinegary. Full-bodied reds, on the other hand, may hold up better and sometimes even benefit from a bit of aeration, though prolonged exposure will eventually soften them too much.

Temperature also plays a role. A warm room accelerates oxidation, so a wine left in a hot kitchen will degrade faster than one in a cooler space. If the bottle was recorked or had only a small amount poured out, it may retain more of its character than one left open in a glass.

While it might not be as vibrant as when first uncorked, most wines won’t turn “bad” in the sense of being dangerous. You might notice a muted nose, a flatter mouthfeel, or a slightly sour edge—but that doesn’t mean it’s undrinkable. In fact, if you’re cooking, slightly oxidized wine can still shine in sauces or reductions.

So, if you’re wondering whether to sip or skip that day-old glass, trust your palate. If it smells and tastes off, it’s best to pour it out. But if it still smells pleasant, it’s likely fine to enjoy. Just don’t expect the same magic as on night one.
