Notes

Based recipe on Buffalo Sweat clone from the TallGrass brewer.
Had to sub Fuggle (bittering) and NB (aroma) for the Glacier.
Using PB2 and Blueberry puree to accentuate CapCrunchPB.
https://www.homebrewing.ai/post/brewing-with-pb2-a-guide-to-crafting-nutty-delights

1) Did a 2-step yeast starter (1L each), starting 8 DAYS before brew day (2d grow, 2d decant, 2d grow, 2d decant). Only had DME for 1L, so used 3x12oz bottles Malta Goya Clasica (Cane Sugar) for the 2nd step, after letting the bottles degas for 2d.
Used the brewersfriend calc: https://www.brewersfriend.com/yeast-pitch-rate-and-starter-calculator/ to confirm yeast count yield
2) Add Fermcap prior to boil
3) Mix PB2 with wort at 15min left and add Lactose at 10min
4) Chill to 62F
5) Fermentation schedule:
62F for 4 days
64F for 4 days
6) Rack to secondary after Gravity stops crashing, adding Blueberry puree, and PMB. Leave for 7-10 days
7) Add PMB when kegging
