I feel like I've got pretty good control and processes on the cold side of things. Pitching rates, ferm temps, sanatization, etc. Now I'd like to really be able to dial in hitting my gravity numbers. I'm looking at getting a refractometer, and I'm going to re-read some stuff on adjusting with water and dme.
What kind of things do you do, adjust, what are your processes, etc when trying to hit your gravity?
