Mostly drank liquor in high school, easiest to get a hold of and more cost effective, I suppose. Rarely I could get someone to buy me a 6'er of beer. Since this was few and far between much of my time was spent talking about and thinking of beer, and shortly thereafter Guinness came into the equation. What I read of it and what most people said about it just sounded magical, so that's what I always went for. When I got into college and beer became easier to get, I started expanding a bit, trying other ales like Bass, Boddingtons, Smithwicks, Newcastle, etc. When I turned 21, I just started trying everything (and spening all my money too, lol). Much of my drinking career has been occupied with delicious ales form the British Isles, and they remain my favorite style to drink and brew - any of them! German/Belgian beers are great and I do enjoy them occasionally, but my mainstay beers are anything English in style. Screw all that citrusy/hoppy american crap! :P
I guess I never really had a 'BMC phase' and I consider myself lucky! I still get made fun of because I don't like it, but hey, that's college, I suppose.
