I take a sample from the mash at 30 minutes. I take it in a large 60ml syringe, for no evaporation effect.
But I wait until it has cooled to measure the pH, sometimes 2-3hr later.
I was blithely going along this route, checking pH w/ different calculators and adjusting next time I made the same recipe based on what I got previously. But my most recent Pils was WAY off and I'm wondering if "time to measurement" might be having an effect.
Recipe #210
Nothing added to the water at all (1/3 potassium Campden for chlorites in 27.5qt full vol mash, ground dusty w corona mill)
