Notes

1) 4 gals Hinkley springs into mash and boil - heat to 164F (a little too low as temp was mash temp 149-150)

2) Add salts and mash in - PH 5.3

3) 75 minute mash, no stir then reciruclate/lauter at finish - about 1 gallons

4) Begin sparge with 4 gallons of room temp pouring 1 gallon about every 15 mins slowly allowing it to rinse grain - ended up about 5.9 gallons

3) Efficiency at 68% as expected - multiple measurements showed 1.068. Measured in hot wort trusting ATC

5) Boil and Hop following recipe, cool then whirlpool. Recirc wort through hop screen during WP hops - clogged a bit due to trub so watch next time

OG 1.077 - need to boil longer next time as 1.081 was target

6) Transfer to Fermenter and shake vigorously - ended up just less than 5 gallons in Fermenter (~4.75g)

7) Cool steady at 67F and pitch decanted starter from fridge, still cold

8) Fermentation started by morning so ~12 hours. 24 hours in and blow-off bubbling hard

9) After 7 days I pitched dry-hop and pumped in co2 through my blow-off rig (has a co2 quick disconnect on a T-valve that can seal from my SS brew bucket)

Measured some FGs and got 1.020 - hit target

10) After 2 days on DH I dropped the temp to cold crash at ~38F and let crash for 3-4 days adding in co2 to keep positive pressure and ensure no oxygen

11) Kegged by pumping out a keg filled with sani into another keg and then closed transferred into the keg

12) Slow and steady carbed at 2.4 vols @ ~38F in kegerator

This beer came out well but I think I was a little heavy on the English malt which was a tad stronger that I would've preferred. Riwaka is a great hop but didn't feel it did great on its own like galaxy or Citra do.
