How long can you keep wine in a decanter?

A decanter is not a preservation tool. It is designed to allow wine to breathe, not to keep it fresh for hours or days. Nevertheless, wine often remains in the decanter after dinner. How long is that wine still good for? That depends on the type of wine, the shape of the decanter, and how you store it. As a general rule: the larger the surface area in contact with air, the faster the wine deteriorates.

What does air do to wine in a decanter?

As soon as wine comes into contact with oxygen, oxidation begins. In the initial phase, this is beneficial: tannins soften, aromas are released, and the wine tastes more approachable. That is precisely the purpose of decanting. But over time, that same process will break down the flavor. Fruitiness diminishes, the wine becomes flatter and can become slightly vinegary. This happens faster in a decanter with a wide base than in a bottle, because the contact surface with air is much larger.

How long is red wine good in a decanter?

Red wine in an open decanter is at its best within two to four hours. Robust red wines with high tannins, such as a Cabernet Sauvignon or a Syrah, will last a little longer than lighter wines like a Pinot Noir or a Gamay. After eight hours, the quality has noticeably deteriorated. After twenty-four hours, the wine is still drinkable but has lost much of its character.

How long is white wine good in a decanter?

White wine is more susceptible to oxidation than red wine. In an open decanter at room temperature, white wine deteriorates quickly. After one to two hours, it loses its freshness and fruitiness. White wine should also be served chilled, which is difficult to maintain in a decanter at room temperature. Use a wine cooler or ice bucket to maintain the temperature longer.

How long is sparkling wine good in a decanter?

Champagne and other sparkling wines should not really be put in a decanter. The large surface area allows the bubbles to escape quickly, and after half an hour, there's little mousse left. Always pour sparkling wine directly from the bottle. Use a champagne stopper to seal the rest of the bottle and store it upright in the refrigerator.

Overview: how long per wine type

Pouring wine back into the bottle

If you know you won't drink the wine within a few hours, it's wise to pour it back into the bottle and put the cork back in. A sealed bottle has less air contact than an open decanter, which slows down oxidation. Afterward, store the bottle upright in the refrigerator, even for red wine. The cold temperature further slows down the oxidation process. Take the bottle out of the refrigerator half an hour before drinking so it can return to drinking temperature.

Sealing the opening to preserve wine longer

If you no longer have a cork or the cork doesn't fit the bottle properly, there are alternatives. A wine stopper seals the bottle airtight and is reusable. A vacuum pump removes air from the bottle and extends its shelf life by an additional one to two days. For sparkling wine, a champagne stopper is the best solution: it maintains the pressure so the bubbles last longer.

If you want to leave the wine in the decanter but slow down oxidation, seal the opening with a suitable stopper or a piece of cling film. This helps, but it doesn't fully replace pouring it back into the bottle. Check out Mémoire's accessories collection for wine stoppers and other storage aids.

Cleaning a decanter if the wine has been left too long

Wine left in a decanter for too long often leaves a residue on the inside. This is a combination of tannins, coloring particles, and dried wine remnants. How to remove this residue without damaging the decanter can be read in how to remove wine residue from a decanter.

The right decanter for your use

A decanter with a narrower opening oxidizes slower than a decanter with a wide neck and broad base. If you regularly have leftover wine after an evening, a decanter with a narrower opening is a more practical choice. If you want to maximize decanting for immediate consumption, then a wide decanter is the better option.
