I have started using that book to create my own recipes within the style framework and the BU:GU ratio is a good one to be aware of in my opinion.
Thanks very much for your thoughts. I admit that I'm a little nervous about the hops profile, because I don't want the Simcoe to be buried under the Munich flavor. Nevertheless, I think I'll stick with 33 IBU, for a few reasons...
1. I want this beer to appeal to my wife, who is not a hop head. She is supportive of my brewing and likes my beer, but I'd be REALLY proud if I could brew a pale ale (if not an IPA) that makes her notice and actually enjoy the hops profile. So I really have to hit that sweet spot, where the hops are noticeable but not aggressive.
2. This beer is based loosely on an APA recipe in Zainasheff's "Brewing Classic Styles," and the OG and IBU of that recipe, though higher than mine, have the same .71 BU:GU ratio that I carefully calculated for my recipe. My OG and IBU are also situated (purposefully) just inside the low end of the style guidelines.
3. I really want to brew a single hop with Simcoe, but I only have 1 ounce! (This will be a half batch.) With my planned hops schedule, I can get to ~33 with that ounce. I've structured my additions to give (I hope) a gentle, anchoring bitter to balance the (I hope) flavorful malt profile, and then to finish with an emphasis on flavor and aroma:
60 min - .33 oz - 25.3 IBU
10 min - 0.25 oz - 7.6 IBU
0 min - 0.37 oz - 0 IBU
Does seeing that flameout addition change your opinion at all about the hops profile?
Again, thanks for having a look.
