This week marked the 50th anniversary of the aluminum beer can, as reported by packagingdigest.com.

The can has come a long way
Cans are not just the home of Bud, Coors, and PBR. In fact, cans are seeing a renaissance in craft brewing with breweries like Maui Brewing and 21st Amendment choosing to can over bottling their product. I poured for both of these breweries at the GABF. They touted cans for their superiority in weight, light blocking, and cooling down once placed on ice or in a fridge.
