How quickly should you finish a bottle of red wine?

How Long Should You Keep an Opened Bottle of Red Wine?

You've uncorked a bold Cabernet Sauvignon or a smooth Malbec, poured yourself a glass, and now the bottle sits half-empty on the counter. How long is it still good for? The short answer: about three to five days, provided you store it properly.

Once exposed to air, red wine begins to oxidize, which gradually dulls its flavor and aroma. But not all reds fade at the same rate. Wines with higher tannin and acidity—like Shiraz, Cabernet Sauvignon, Merlot, and Malbec—hold up better after opening. Their structure helps them resist spoilage a little longer, making them more forgiving if you prefer to sip slowly over a few evenings.

To get the most out of your bottle, seal it tightly with a cork or stopper and store it in a cool, dark place. For even better results, especially in warmer climates, pop it in the fridge. The cooler temperature slows oxidation, helping preserve the wine’s character.

Lighter reds, such as Pinot Noir, tend to degrade faster—sometimes within two to three days—so it's best to enjoy them sooner. By day four or five, even sturdier reds may start to taste flat or vinegary, a sign it's time to pour a fresh bottle.

So while you don’t need to finish a bottle in one sitting, aim to savor it within the week. With proper storage, most quality reds will remain enjoyable for up to five days. The key is respecting the wine—store it right, and it’ll reward you with one more good glass.
