Lore has it that A-B's big brewery near Baldwinsville was the last place in the U.S. to produce beer balls, ending production possibly as late as 2007. So the comet-like fad of the beer ball started -- and may have ended -- in Upstate New York.
Another type of mini keg is the "beer ball" or the "party ball", a disposable plastic ball that usually holds around 5.2 US gallons (20 l), roughly the equivalent of 55 twelve-ounce beers, though they can also be found in a smaller 3.8-US-gallon (14 l) size.
