What constitutes a good beer?. On one hand. You have people saying Budweiser, Bud Light, Michelob...taste like "piss water". Then will precede, to hand you a Keystone or Busch, and state, "Here's a real beer!". Those are one less carbonated bubble away from water, if you ask me . Not that I'm sticking up for mass beers. Just that when the argument presents itself, they always grab the most heavily diluted brand and claim it's, "Real beer".
