16/12 Combinations Letter “C” ; The 16 ounce Canadian Ace Beer and Ale were fairly recent additions and came from a Dealer’s Site, I jumped on them as I never saw them available before. Champagne Velvets are from Atlantic Brewing, Chicago! The tall Coors can is a 15 ounce can but pay attention to the 12 ounce can, it’s the Steel version and is rarely seen! Coors may have been the first American Brewery to mass produce their own Aluminum cans and even sold other breweries slugs/cans to use for their products giving them a major price advantage in a very competitive market!
