You opened a bottle two nights ago, it’s sitting half full in the fridge, and you’re wondering if it’s still drinkable or destined for the sink. The answer depends heavily on the type of wine, and it’s more forgiving than people assume for some categories and far less forgiving for others.
Light, high-acid whites: 5 to 7 days. Their high acidity acts as a natural preservative, slowing oxidation.
Fuller, oak-aged whites: 3 to 5 days. Lower acidity means they oxidize faster.
Light reds: 4 to 6 days. Lower tannin means less natural resistance to oxidation.
Full-bodied, tannic reds: up to 7 days, sometimes longer. Tannin acts as a natural antioxidant.
Sparkling wine: 1 to 3 days, and only with a proper stopper. Once the bubbles start escaping, there’s no bringing them back.
Fortified wines: weeks, sometimes over a month. Higher alcohol content acts as a strong preservative.
Three things that genuinely extend life: store it upright, not on its side; refrigerate reds too, even though you’ll serve them at room temperature; a vacuum pump or inert gas spray genuinely extends life for still wines.
The simplest test, regardless of any of these numbers: smell it before you taste it. If it smells flat or like bruised fruit rather than fresh, that’s oxidation telling you it’s past its best.
