Cold crash for 2 days. Transfer to serving keg with clear beer draft system, gelatin, and campden tablet. Burst carb. 8/5: accidentally added all water salts and lactic acid with first infusion. Only added campden tablet the rest of the way. Mash temps of 128°F/150.6°F/152°F. 1.055, 5 gal. SP is 50°F with dip tube converted to thermowell. 8/7: pitched yeast.
