I'm a big fan of beer. Any kind of beer really, because even the crappy ones have a purpose. Coors Light, for example, tastes like watered down water, so it's an excellent getting drunk beer, and the local bar does 4 for 1s on Coors every Thursday, so I've gotten used to the taste and getting smashed off of it. So really, I'll drink and enjoy about any beer you throw my way.
However, my all-time favorite has always been a New Belgium 1554 [http://www.newbelgium.com/beer/detail.aspx?id=5ac72c92-fd87-4ec7-858d-3380c8d465d8]. It's a dark beer without the heaviness of a Guinness, with a decently high alcohol content and an excellent flavor. Definitely my favorite of all time. In fact, I'm a big fan of most of New Belgium's 1554 beers. Lately I've been on a La Folie [http://www.newbelgium.com/beer/detail.aspx?id=4e583fd6-95e4-4ea0-908c-4436f5dc8fa8] kick, which has been a bit of a drain on my wallet, but well worth it. They brew the beer, then age it in old wine barrels that give it an extremely sour flavor. It ends up being like drinking juice in beer form.
Another of my favorites is the Bar Harbor Blueberry Ale [http://www.atlanticbrewing.com/beer-3.htm]. It's got a strong blueberry flavor, so it's not the kind of beer that you'd down an entire six pack at once with, but having one or two at a time with dinner or whatever makes that dinner exponentially better.
As far as other types of alcohol go, I'm a fan of mead (I've been known to drink an entire bottle by myself in a night). Vodka is always right up my alley, as is most rum (The Kraken is my favorite by far, but by no means the only thing I enjoy). Mixed drinks are good, but I'd usually prefer straight alcohol or something simple like a rum and coke. However, there's another bar close by called Luscious Nectar that makes their own slushee-type beverages, and most of those are pretty spectacular. The Adios ************ is the only way I drink tequila. Not sure what's in it exactly, but it's got fruit of some sort and it's radioactive blue in color. It tastes spectacular despite the tequila in it. It's the blue one on the right [https://foursquare.com/v/luscious-nectar/4a90cc83f964a5207e1920e3/photos?openPhotoId=502d6593e4b07f4738d4ae16]
Shit, you know, I'll drink just about anything that's handed to me.
