We may drink a large quantity of piss beer here in America (bud light, coors light, etc.) but the fact of the matter is that you can easily find excellent beer, either from around the world or U.S. microbreweries, with basically zero effort.
Example #1: my local Ralph's (the biggest grocery chain in southern California) sells Franziskaner, Fin du Monde, and Rogue brewery beers, among many more.
Example #2: nearly every bar, even the most generic hole of a sports bar, has *some* kind of microbrew, be it Sierra Nevada, Fat Tire (New Belgium), Pyramid, or Shiner.
Note: the overwhelming majority of piss beer is now imported or manufactured by foreign-pwned companies such as InBev. The largest U.S.-owned breweries are now Yeunglings and Sam Adams. Sam Adams brews almost every type of ale or lager you'd want, some of which are pretty decent.
