I brewed a 10 gallon batch of Eschatz's recipe http://www.homebrewtalk.com/f69/bell...ey-come-91488/
for Two-Hearted Ale Clone with a friend a couple of weeks ago.
I used Safale 05 yeast. I let it sit for two weeks in primary as the krausen just didn't seem to want to drop. I racked it to secondary on Sunday and added the dry hops. This is a very nice recipe. Bitterness is fairly subtle for an IPA. The flavor and aroma are there, but the malt bill comes through more than most IPAs.
I will agree with the other posters that Amarillo is NOT a sun for Centennial. The flavor of Amarillo is far more floral. Centennial is more dry.
If you like SN Celebration Ale you might want to try my recipe for Vail Pale Ale http://www.homebrewtalk.com/f69/vail-pale-ale-60215/
Back in the day, I managed to Gold at GABF with this recipe over Celebration Ale, even though I based it on SNCA
Who can tell what judges will like?
