It's been a while since I've had hop wallop, I think I've only had one bottle of it, but it is delicious, I remember that. Here's what their website reveals:
As our annual homage to the hop harvest, expect loads of aromatic splendor and bitter beauty.
Malts: Imported German malts
Hops: American whole flowers
Alcohol by volume: 8.5%
Based on that information, you've at least got origin country sourcing. Go for a distinctly German malt bill and strictly American hop varieties, like the "big Cs": Crystal, Chinook, Cascade, Centennial, and Columbus.
