When I turned 21, I don't remember what I drank, all I know is it was a LOT of it since I don't remember a damned thing. Probably mostly liquor. If I had to guess, at least into the double digits of Jameson shots.
As far as my birthday this year, my wife bought me a bottle of Cantillon Fou'Foune while we were out for dinner. Man was that delicious. Also grabbed the Stone Enjoy By 2.15.13 IPA for myself as a gift, but that was a couple days early.
As far as the next few years, I'll be opening one bottle from the brick of Westy 12 I picked up in December.
