Practically any kind of beer, depends on what I'm in the mood for. I'd recommend American Monastic by a brewery called Clown Shoes, a nice IPA I've had recently.
During the summer a good, dry English or Irish cider in the sun is lovely. As for non-alcoholic it's mainly water and the occational soft drink/energy drink, Portello and Trocadero are the shit if you can find them near you.
