My last batch was a porter with a really acidic grist. 10 gallon batch, grist was:
Maris Otter - 13 lbs 1 oz
Brown malt - 2 lbs 12 oz
Crystal 75 - 1 lbs 13.5 oz
Chocolate malt - 1 lb 6 oz
In order to get the pH in the right range, I added 8 grams of lime to my 6.7 gallons of mash water. Brewer's Friend predicted pH of 5.46 at that amount of lime. I ended up with a pH at 15 minutes of 5.31. I figure that next time I need to go to 11 grams to hit a pH of between 5.4 and 5.5, which is my target.
With my other salt additions, according to Brewer's Friend 8 grams of lime brought my water to:
Ca 97.7 ppm
Mg 8.3
Na 10.6
Cl 35.4
SO4 54.9
is there a problem adding that much lime to get my pH in the intended range?
