Favorite beer... probably Gulden Draak, a Belgian strong dark ale. Stuff is expensive, though. :( Delirium Nocturnum is another favorite, and in the same style. I'm also in love with just about anything brewed by Terrapin out of Athens, GA, but having moved recently, I'm still searching for someone who carries their stuff.
As far as other alcoholic beverages go? I love bourbon. I don't always feel up to drinking it straight, in which case I'll mix it with Sprite, 7-Up, or something of that nature, but I do love it with just a tiny bit of water. As much as I enjoy the taste of the alcohol itself (and I do), a little water helps to open it up so you can taste everything else.
