# Does Beer Expire? Understanding Its Shelf Life and Storage Secrets When enjoying a cold pint or savoring a craft beer, one common question pops up: Does beer expire?

In this article, we’ll explore whether beer expires, how long it lasts when stored properly, and the key factors that affect its freshness—so you can enjoy your favorite brew at its best. ## The Science Behind Beer Shelf Life Beer is primarily composed of water, fermented grains, hops, and sometimes yeast, alcohol, and flavorings.
