I'm allergic to brewers yeast, so I have to drink beers that are filtered. That means mostly macro-brews, so I drink Bud Light most of the time. It's hardly beer, but it's a beer-ish flavored sody-pop that I can enjoy.

I can get away with one "real" beer from time to time, but anything more than one of a non-filtered beer and I'll really regret it.
