Most of the time bourbon, whiskey, or scotch on the rocks. I also like vodka martinis. IPA's, stouts and porters. When it gets hot I like lite beer with a lime or one of my new favorites is a Michelada.

6 oz lite beer or Mexican beer
2 oz Zing Zang Bloody Mary mix
Squeeze of lime
A couple of dashes of Tajin seasoning

Put all that in a 16 oz glass of ice and stir.

Those are especially good in the mornings when you start drinking a little early while on vacation in the islands. It's a drink you can pretty much drink all day because it's pretty low in alcohol. Only half of a pretty low alcohol beer at a time. I make mine with Michelob Ultra, so they are pretty low calorie too.
