In the realm of beers, I tend to like stronger ales (reds & browns over pale), although depending on what I'm eating, hefeweizens aren't bad at all.
In wine world, I'm pretty middle of the board -- not too sweet, not too dry. That's an area typically occupied by blushes, but also a handful of whites and reds. Some varieties vary a lot -- Chenin Blancs can be anything from very dry to very sweet. Typically, this also includes wines that aren't too expensive, as well as beverage wines like sangria (although I guess that's technically a "wine beverage"). Generally don't like dessert wines, but if I were to go for sparkling wines, I prefer sweet over dry.
I happen to be fond of sake, and I find a lot of them especially go well with strongly flavored food (e.g. really spicy or really salty or really sour or whatever).
Mixed stuff... hmmm... rum/Crown & coke, buttery nipple, whiskey sour, dark/white russian, SoCo & Dew, there's a load of good ones out there and people occasionally dream up some interesting ones at times that might have otherwise seemed like total nonsense.
Plain hard liquor, then I'm a scotch/whiskey man, though I don't mind Southern Comfort. Though I find with hard liquor that it pays to be a brand whore. I've found some brands that are decent and some that are just god-awful. For instance, I can't stand Jim Beam -- it's turpentine. Which is also why I basically never buy hard liquor myself : the good stuff is just too expensive.
