It's not cheap, but if you ever see the Dogfish Head World Wide Stout (currently 18% abv), treat yourself to a bottle (no they don't come in 6 packs.)
I had the Sam Adams Triple Bock over a decade ago. That stuff was around 20% alcohol I think. It was nasty. I'm not ever drinking beer that strong again!
