I am trying to figure out the Mash Chemistry and Brewing Water Calculator. When I build the recipe with the My Recipe function it shows a mash pH of 5.94. When I build the recipe using the Mash Chemistry and Brewing Water Calculator is shows a mash pH of 5.84. Can anyone explain this 0.1 discrepancy? For the record, I want to brew an 8-gallon batch with the grain profile shown but will do a BIAB mash in 5 gallons to help reduce the mash pH. I understand I could mash even thicker like in 3 or 4 gallons if I wish. After the mash, I check my gravity to verify I had a good conversion. I will dilute by adding 2 gallons of water to bring my kettle up to 7 gallons and then boil for 1 hour. I will lose 1 gallon of water during the boil leaving me 6 gallons post-boil. To help cool the wort, I will add 2 gallons of refrigerator chilled water to bring my wort back up to 8 gallons. And then I will chill in my poor man’s ice bath.
