Beers have dates? Would I make a website about it if they didn't? Most beers sold in North America have a stamped on them.
Not sure what's used in most bottles, but the Julian format I'm used to in database programming is like this: 109054. It simply means: 1st century (1) 2009 (09) 54th day of the year (054) So it's Feb 23, 2009 in this example.
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 and/or. How do I read them? Just select a brewing or distilling company from the list below to learn about its product-dating system. If I haven't listed a brewery here, it means I haven't figured out the brewery's dating system (or more likely, it's a regional brewery I haven't heard of), so please don't send me e-mail asking about it. If, on the other hand, you have (good) information about a brewery not listed, please and I'll give you credit for the resulting entry.
