Does Beer Expire?
Beer does not expire in a way that makes it unsafe, but its flavor degrades over time. Most beers are best consumed within 3-6 months of packaging. Hoppy beers like IPAs fade fastest, while high-alcohol and dark beers age better. Proper storage extends freshness significantly.
Key Takeaways
- Beer flavor degradation is caused by oxidation, light exposure (skunking), and temperature fluctuations.
- Some high-alcohol beers like barleywines, imperial stouts, and Belgian quads can be cellared for years and may improve with age.
- Bottle-conditioned beers with live [yeast](/does-yeast-expire) may also age well under proper conditions.
Explanation
Beer flavor degradation is caused by oxidation, light exposure (skunking), and temperature fluctuations. The hops that give IPAs their characteristic flavor break down quickly, making these beers best fresh. Malt-forward and high-alcohol beers are more forgiving.
Light causes a chemical reaction in beer that creates 'skunky' off-flavors, which is why brown bottles offer better protection than green or clear glass. Cans block all light and are excellent for hop-forward beers.
Store beer cold and upright in a dark place for longest shelf life. Most craft beers have a packaged-on date rather than an expiration date. Beer that has gone stale is safe to drink but may taste cardboard-like, overly sweet, or simply flat and dull.
Things to Know
- Some high-alcohol beers like barleywines, imperial stouts, and Belgian quads can be cellared for years and may improve with age.
- Bottle-conditioned beers with live yeast may also age well under proper conditions.
- Skunked or old beer will not make you sick, but the unpleasant taste may cause you to want to stop drinking it.
