I only drink the majors. Macrobeers taste skunky. I don't drink any brand that has been created after 1960...the year I was born.
The oldest beer in North America is Molson, btw.
I like Rolling Rock.
For imported I drink Boddingtons, Molsen Golden, Fosters, Sapporo, Grolsch...or anything German. It's impossible to get a bad German beer.
