Not sure if they come in cans or not, but some stouts range to 12%. Ha, so there :P IPA's.
But i don't drink to get drunk--actually i don't like being drunk. Slightly buzzed is more than enough for me, so really i don't care too much about ABV levels in actuality, and despite my mucho Celtic and familial alcoholic heritage, i'm a lightweight for sure.
My very favorites are Oatmeal stouts, all in all.
