I've noticed that younger people tend to say their favorite beer is some sort of stout flavored microbrew.
beers that are almost a mix between a lager and a wine cooler. I'm not hating, I just find that interesting. Either people under 21, or newly 21, really like fruity and or dark/stout microbrews, or they are just trying to impress people with their beer knowledge.
anyway... as an everyday watching the game beer, its usually miller lite or coors light. Bud light is fine too. If I'm at a bar or something, or just feel like, I'll get belgium brewing company's sunshine (same company as fattire).
I like rolling rock and greenlight too.
