I agree with Revvy's early post - lighter beers. In particular, I love brewing (drinking) Helles, Dortmunder, British Mild, Brittish Bitter . . . . session beers. I like the challenge of brewing an awesome tasting beer that is 1.035- low 40 range. It is not easy to do, especially if it is a "golden" beer. Lagers in general as well - especially german beers ( pils, oktoberfest, maibock, etc.)
Also have become interested in sours a bit as others have mentioned too. Rodenbach is a favorite and the one that got me hooked (along with a New Glarus Cherry Stout.)
What am I less interested in to offset this? Crazy beers (odd additions, fruit, spice, etc. etc. etc.) I used to always see a recipe and thing "what can I add to it to make it "better" (which usually made it worse).
