Use FreshBeerOnly.com to figure out the silly codes on your cans and bottles (assuming it isn’t obvious). They even remind you on the homepage which beer styles are best fresh and which ones can be aged.
A reminder that the majority of craft beers (with the exception of those which are able to be cellared) that aren’t intended to be aged usually have just over a 3 month shelf life (100 days or 1/3 of a year). Each brewery has their own method of freshness suggesting.
This is a pertinent topic … because we had to get rid of quite a bit of the wheat beers that we still had stock of that were brewed back in February. The spoiled taste was reminiscent of vinegar. Our public service announcement this week is to drink your beer in a timely manner!
