How to Store Opened Beer in Refrigerator

Opened a beer and couldn't finish it? It happens. While beer is best enjoyed fresh, you can store an opened beer in the refrigerator for a short time if you seal it properly. Here's everything you need to know.

How Long Does Opened Beer Last in the Refrigerator?

Opened beer lasts 1 to 2 days in the refrigerator before it goes flat and loses its flavor. The carbonation escapes quickly once the seal is broken, so the sooner you drink it, the better.

• Bottled beer (with a stopper): 1–2 days
• Canned beer (transferred to a sealed container): 1 day
• Draft beer: Best consumed immediately; 1 day maximum

Step-by-Step: How to Store Opened Beer

1. Seal the Bottle Immediately

The moment you stop drinking, seal the bottle to slow carbonation loss. The original cap won't work once it's been pried off, so you'll need a bottle stopper.

A good bottle stopper creates an airtight seal that keeps some carbonation intact. Look for stoppers designed specifically for beer bottles with a flip-top or clamp mechanism.

2. Store Upright in the Coldest Part of the Fridge

Store the sealed beer bottle upright in the coldest part of your refrigerator — typically the back of the middle shelf. Cold temperatures slow the loss of carbonation and keep the beer fresher longer.

3. For Canned Beer: Transfer to a Sealed Container

Open cans can't be resealed. If you have leftover canned beer, pour it into an airtight container or a bottle with a stopper. This isn't ideal, but it's better than leaving it open.

4. Minimize Air Exposure

The less air in contact with the beer, the better. If you're using a container, fill it as close to the top as possible to reduce the air gap.

Does Refrigerating Beer After It's Been Warm Affect Quality?

There's a common myth that beer "skunks" if it's been warm and then re-refrigerated. This is mostly false — skunking is caused by light exposure (especially UV light), not temperature changes. Re-refrigerating beer that's been at room temperature is perfectly fine.

Tips to Get the Most Out of Leftover Beer

• Use a bottle stopper immediately after opening.
• Store upright in the coldest part of the fridge.
• Drink within 1–2 days for best flavor.
• Use flat leftover beer for cooking — it works great in beer bread, marinades, and batters.

Signs Opened Beer Has Gone Bad

• Completely flat with no carbonation
• Stale, cardboard-like smell
• Sour or off taste
• Unusual color (for light beers)

Flat or stale beer won't make you sick, but it won't taste good. Use it in cooking rather than throwing it away.

Quick Tips for Storing Opened Beer

• Seal immediately with a bottle stopper.
• Store upright in the coldest part of the fridge.
• Drink within 1–2 days.
• Use flat beer for cooking — beer bread, stews, and marinades love it.
