I have 7 varieties in the ground, 6 that I "cropped" last year, and 1 Willamette as an oddball this year. I say cropped kind of tongue in cheek, Cascase and Zeus did very well, Northern Brewer, Fuggle, Perle did ok, and Saaz was so low it shouldn't count.
So far I find them much easier than cranberries (my former crop) and I sure like what they go into! I don't brew but have a nanobrewery on site so my goal is profit focused. I grow what the brewer asked for (Zeus was my idea) so I have no marketing to do.
I don't know much but will be happy to share what I do. Paul
