Amarillo Coffee Blonde

I recently started brewing again after a several month hiatus, largely inspired by the kegerator (keezer, actually), that Rachel and I have been slowly assembling. In an effort to look for new things to make and desperately wanting to fill 5 kegs worth of beer, I stumbled across the Mad Fermentationist’s recipe for a Blonde Ale on Coffee Beans.

I wanted, like usual, to adopt and modify it to make it somewhat my own, so I simplified the grain bill by tossing out the oats and going with a lighter crystal malt. I also have a lot of Amarillo lying around, and it’s a really nice hop with a profile (quite floral, tropical, citrus) that should mesh nicely with a lightly roasted coffee from Stumptown: Ethiopia Duromina described as having notes of lemonade, hops(!), and peach.

I fermented this with an English ale yeast (S-04), but did so at a pretty low temp (62-63 for most of the time, rising to 68 at the end of active fermentation) to keep it a bit cleaner.

I racked it to the keg this weekend and it’s been on the beans (2.2oz) for 36h. I took a sample last night that was very nice, pretty clear coffee flavor with a reserved aroma. I’ll pull the beans tonight (~48h) and start carbing – looking forward to this one!
