Gosh, I think I drink harder than some of the fellas on this board... not sure that's a good thing, but oh well. I'm a Mexican artist, afterall.

My current favorite cocktails (made with Maker's Mark):
Manhattan
Godfather (made with my homemade amaretto)
Mint Julep
Whiskey Sour

When I drink tequila (Patron Silver), I usually have it straight or on the rocks with real lime juice and triple sec (NEVER bottled margarita mix).

For vodka, I like Stoli and Grey Goose. White Russians are always good, though Caipiroska is my favorite vodka drink right now (uses a whole crushed lime).

As for beer, I've recently discovered a local micro-brewery and really like their stuff. Otherwise I drink Dos Equis and Corona.

If you're ever looking to try something new, I micro-blog various cocktail recipes that I come across: http://twitter.com/Mixologist.
