Notes

Goals:
___
-BU:GU ratio ~1.10
-Adjust knockout time to get to 175F and adjust whirlpool additions accordingly to keep IBU in range.

Goal mash pH 5.3.
Mash recirculation power 45%
-Boil 50 minutes, wait 10 minutes before first hops
-At 10 minutes remaining check pH for goal pH 5.0
-Oxygenate wort for 30 seconds.
210 billion yeast cells required
Each pack reporting at least 110B so ~20 g yeast total should do. (7gram each)
-Ferment at 3 psi
-Once within 0.05 gravity points of FG raise temp to75 F and let PSI climb to 10
-Drop yeast after final gravity stable 3 days
-Drop temp to 58F and dry hop.
-Cold cash to 40 F
-Add ascorbic acid to keg for final beer pH 4.5
-Purge keg with CO2
-Force carb to 2.5 vol
