title_body: Where can I find a type of beer that comes in flat top beer cans?
upvoted_answer: You are in luck! There is a retro can operation called the Chuchkey Beer Co. that is canning beer in the old style flat top cans that you need a churchkey to open (I think they supply one with the case). Looks like it's only available on the West Coast. Enjoy it if you can find it! Chuchkey Beer Co.
