Kitchen Sink IPA
I just brewed this yesterday, and it is a tweak to my first IPA recipe a few months ago. I also had quite a few miscellaneous hops in the freezer left over from previous batches, which is why this is called the "Kitchen Sink" IPA. This is also why some of the hop addition amounts are strange :D. The Perle and Select Spalt were just some random whole leaf hops I had left over, but those could be replaced with anything really. Centennials for bittering and aroma would be a great companion to the Magnum and Cascades. When I do this one again, that's what I'll be using. I plan to dry hop in the keg, by zip tying a bag full of hops to the dip tube about halfway down in the keg. One keg will get Cascade, the other will get Centennial...just to keep it interesting. When I get near the end of these kegs, I may blend them together just for fun.
I mashed at a low temperature (150F) for 75 minutes on this one to acheive a more fermentable wort and lower final gravity. I also added 1# of corn sugar to add some fermentables without adding any residual sweetness. I also raised the temperature at the end of fermentation to 75F, which I've found helpful to rouse the yeast and consume any sugars still left behind. If you have any suggestions, please let me know...as this is just my third IPA I've ever brewed I'm eager to hear input from more experienced brewers. Thanks!

1.00 lb Corn Sugar (Dextrose) (0.0 SRM) Sugar 3.51 %
2 Pkgs US-05 Dry Yeast
1. Mash 28.5# of grain @ 150F for 75 minutes - used 8.6 gallons of 168F strike water
2. Fly sparge with 8.4 gallons of 175F
3. Collect 13.5 gallons of wort in the boil kettle
4. Boil for 60 minutes
5. Cool to 72F and pitch dry yeast (no starter)
6. Ferment for 21 days @ 65-68F (wort temp)
7. Raise temp to 75F for 2 days, then crash cool for 3 days
8. Keg and force carb at 30psi for 2 days
9. Store for 7 days @ 12psi
This fermentation started right off the morning after brew day, less than a 12 hour lag. The wort temp is a little warmer than I would like @ 70F instead of 68F. I noticed that today and dropped the fridge temp down a couple degrees, so hopefully the higher temp won't have an adverse effect on the flavor of the beer. Pretty active fermentation, but did not form a huge krausen like I expected.
Holy farkin attenuation!!! Just checked my gravity on my IPA...and it's reading 1.012 on one carboy, and 1.010 on the other! :D With an original gravity of 1.070 that's an apparent attenuation of 84.9%! Oh yeah, and a 7.8% ABV :drunk:. I guess I'll need to label this one an Extra IPA?
Not sure if it was mashing @ 150F for 75 minutes or what but I'm stoked. At this point it still has a way to go before I can secondary and dry hop, but the sample tasted great. Plenty of hop aroma from the FWH and last hop additions. Pleasing bitterness, but doesn't overdo it. I think this is going to be one fantastic brew!
I applaud you for your low bitterness and though I am not going to go out and buy the hops that you used just for this beer, I will definately try your method of hopping and mashing. Good on you.
I just redid my IPA and mashed lower in order to get the attenuation, though I think next I will mash around 148 to get it even lower. 1.080 OG without the sugar. Let us know how this one turns out so that I can copy and pilfer with need ;)
