If stored refrigerated, how long can bottled beer last before becoming noticeably off?

Bottled beer that is stored in a refrigerator can generally maintain its freshness and quality for up to six months. This timeframe is based on factors such as the beer's style, alcohol content, and whether it has been pasteurized or is a living beer with active yeast.

Most lighter beers and hop-forward styles, such as IPAs, are best consumed fresh, often within a few weeks of packaging, to preserve their vibrant hop aromas and flavors. However, when they are kept cold and away from light, they can maintain an acceptable taste profile for about six months.

Other styles of beer, such as stouts or barrel-aged beers, might last longer if stored properly, but six months serves as a general guideline for optimal consumption of most bottled beers. Beyond this point, the beer may still be safe to drink, but it could exhibit flavor degradation or be perceived as off, particularly if exposed to light or warmth.
