I just discovered this article from foodandwine.com about one of my favorite, and one of the oldest breweries in the world, Weihenstephan collaborating on a new beer with Sierra Nevada!
It's a hoppy wheat beer Braupakt ("Brewery Pact") that uses the German Hallertauer hop and the West Coast Amarillo and Chinook varieties. It'll be out in limited release this April. Keep an eye out for it!
