The independent consumer guide to beer product dating.

Welcome to, one of the weirder sources of consumer information on the Web. This is where you come to learn how old that can of beer you're holding really is. Got a suspiciosly skunky beer? Trying to date a collectible? Here's where you start.

Beers have dates?

Would I make a website about it if they didn't? Most beers sold in North America have a production code stamped on them. Beer cans are always stamped on the bottom. Bottles are usually on the necks, but sometimes the date is on the label.

Most American beers use expiration dates, but some use bottling/canning dates. Unless otherwise noted, domestic beers have a shelf life of approximately four months, but imported brews last a year after bottling.

For more information on understanding production dates, why you want to understand them, and who created this site, you can read the vastly more amusing FAQ and/or skim the glossary.

How do I read them? is the independent consumer guide to beer product dating. It is not owned, operated, affiliated with, or endorsed by any brewery or brewing company. In other words, if you want to send e-mail to a beer company, don't send it to me.
