My favorite for the summer days is blue moon, unfiltered witbier, nice orange/citrus flavor, and I usually put a lime in too.

Update: tried the flying mouflan from troeggs brewery, it's right up my alley. Sweet and bitter and hoppy. Damn it's good. And a little over 9% alcohol by volume. I think I'll even pick up a growler of it when next I'm around Harrisburg, pa, if I can get up there before the season for it ends.
