Yes, you can technically drink beer after its expiration date, but the experience may be less pleasant. Here’s a concise guide to what to expect and how to decide: What happens to expired beer

• Safety: Beer generally remains safe to drink after its date because alcohol and acidity deter harmful bacteria. It’s unlikely to cause illness if the can or bottle is intact, sealed, and not damaged. However, flavor and aroma can deteriorate.

• Quality changes: Over time, beer can become flat, dull, oxidized (cardboard or stale off-flavors), or light-strressed if exposed to light. These changes don’t make it dangerous, just less enjoyable.

• Signs to avoid: If the container is swollen, leaking, or has a strong metallic/off odor, discard it. If it tastes or smells particularly unpleasant, it’s best to pour it out.

Practical tips

• Check the container: Ensure the can or bottle is undamaged and not swollen. A corked or pressurized container that looks abnormal should be discarded.
• Inspect the beer: Pour with its usual head if possible; if it’s unusually flat or oxidized, you’ll likely notice it immediately.
• Compare and decide: If you’re unsure, try a small sample and compare to a fresh example of the same style. If it’s notably off, don’t drink more.

Bottom line

• It’s generally safe to drink expired beer if it’s stored properly and shows no signs of spoilage, but the flavor may be compromised. When in doubt, err on the side of caution and choose a fresh can or bottle.
