Had some to test so I found a use for it. The other hops were all cyro (lupulin powder) I had to test with from CBC, and I wanted something to round out the mix and give some of the more stable oils not found in just the lupulin glands.
Yes, Many pro breweries avoid the Blended hops or do limited releases to test when a new blend comes out and then move on some have had success with them, however Founders Zythos IPA did not succeed.
