My usual favorites are Amaretto Sours, Mike's Hard Lemonade, or Smirnoff Ice. I also like Chateau Morrissette's "Our Dog Blue", which is a white wine put out by a Virginia winery.

Chateau Morrissette wines are usually very good and not too expensive. Also, I love their labels, because all of the designs for the labels include a black labrador retriever. (Their dog is the official mascot of the winery).
