Under refrigeration, what is the maximum shelf life of beer?

The maximum shelf life of beer when stored under refrigeration is six months. This guideline is particularly relevant for most styles of beer, especially those that are hop-forward like IPAs, as they tend to be best enjoyed fresh to retain their aromatic qualities and flavor profiles. When beer is kept cold, it slows down the oxidation and microbial activity that can lead to off-flavors and degradation over time.

While certain stronger or darker beers may age better and could last longer, the six-month mark serves as a general standard for optimal freshness, particularly for lighter and more fragile styles. It's important to note that while refrigeration can prolong the shelf life compared to storage at ambient temperatures, beer generally does have a finite period in which it retains its intended flavor and character.
