Converted this recipe to my own and testing out pressure fermentation and closed transfer to reduce oxygen. Scaled down to ferment with enough headspace in a corny keg.
Recipe:
85% pale 2 row
10% oats
5% carafoam
London Ale III (use A38 Juice as a backup)
20 IBUs of magnum at 60
5 IBUs EACH of citra, simcoe, amarillo at 20 mins
Exact same amounts at flameout
whirlpool for 10 mins, let settle for 10 mins, then chill
guidance is 15g/liter dry hops split equally between each hop. 4 gals is roughly 15 liters. 225g = 8 oz. 2.6 oz of each hop. 0.6 of each hop is regular. 2 oz of each regular hop is 1 oz of the cryo version.
Dry hop with leftover Citra/Amarillo/Simcoe from boil (0.6 of each)
plus 1 oz each hop in cryo version.
Ferment at 68F, spund at 2-4 psi (purge keg method) to start, use floating dip tube, add dry hops in bag with magnet attached to lid
Turn up pressure to ~15 psi around 4 days into fermentation.
Finish up primary fermentation around 7 days
crash to 60F and release dry hop charge with magnet
dry hop for 4 days, then crash to 35F
closed transfer to purged keg, put on gas and serve
