Brewing up a Dunkelwiezen tomorrow, and I can't get the german Hallertau. I have acces to American Hallertau, but I don't want to make the 2 Hour Commute to the Home Brew Shop. The hop addition is a simple 60 minute boiling hop, so I don't think I'll taste a difference. I have Cascade at 6.9% Alpha, and East Kent Golding at 5.0% Alphas. I am looking for right around 14% IBU's. Which do you think I'd be better off with? And do you think it really matters which one I use?
