Now, I am no expert on Hefeweizens, but here is my list. In no particular order.
Ayinger
Schneider-weisse
Weihenstephan
And, it may not count, because it is a Kristalweizen, but Black Raven's Sun Thief over here in Redmond got me back into drinking wheat beers, after one too many American "Hefeweizens".
