Well, what a glorious clusterf*** I made of this! Things got a little crazy Saturday, so I wound up forgetting the recipe when I went to the LHBS. I thought I remembered pretty well, and I picked up 8lbs of light DME, a pound of crystal 40, 4oz of Centennial and a vial of WLP060 (they were out of Nottingham). I was playing with the recipe in BeerSmith and decided to add an oz of Simcoe to the bittering hops (since I had some lying around). Get around to measuring everything out and it wasn't until then that I realized I had Centennial instead of Cascade. Plugged the change in BS and lo and behold! 50+ IBUs! Since I'm making this for a family event, that was way too much. But of course, I had already measured out the hops and mixed in the Simcoe. So I wound up just using the 2.5oz of Centennial and the oz of Simcoe at 15min (still 45 IBUs), haven't decided if I'm going to to ahead and dry-hop yet. Tasted the wort and hated it. I don't like Centennial, and there was a lot of it. I also measured my OG as 1.072, which doesn't seem possible (I only used 6# of DME). I'm going to pick up some Cascade or maybe EKG and make another batch next weekend, and I'll take both to the party and use them as educational exhibits. Glad I have lots of guys at work who like my stuff, because I think I'll be giving most of this batch away.
Looking forward to finding out what this recipe *really* tastes like, since I don't think I'll be enjoying my "variation"!
