You mean alcoholic beverages and/or normal beverages?
Normal: Ice tea, lots of it. At work usually double espresso's.
Alcoholic: Usually the cheap stuff (pina colada, apfelkorn, stuff like that) when i feel like it. Just empty the bottle and that's it. Some beer here and there. But on (and much more enjoyable) rare occasions i like to share an old whisky with friends. Still have some 17 year old Johnny Walker.
