I recently sampled some (lots of) Hefe-weizen at the Capitol City Brewing Co. in DC that makes their own beer. This is their link. It's not listed on their page, but it's a great summer beer. Light, wheat beer that goes great with a slice of lemon. That's right, lemon! Some mock the lemon addition, but it is really good. I usually like a nice bitter or ale, but summer calls for lighter fare, and Hefe-weizen is just the ticket. Paulaner and some other brands make a bottled version. Try some when it's hot. And don't forget the lemon!
