I have a PH question on BIAB. I brew mostly blonde beers and PH seems to be a challenge with BIAB. I use brewers friend. A recipe with
9 lb German - Extra Pale Premium Pilsner Malt
1 lb German - Vienna
0.5 lb Belgian - Biscuit
0.25 lb German - Melanoidin
1 lb Belgian Candi Syrup - Simplicity
0.5 lb German - Pale Wheat
I use RO water and add salts
Water targets
Ca Mg Na CL So4
32. 9. 5. 36. 23
Salts
3g calcium chloride
1g gypsum
1g Epsom salt
Acid
8ml phosphoric acid 10%
Calculates a PH of 5.5
I want the PH at 5.3 or less
This would require 50ml of phosphoric acid or a lot of calcium and push the CL up to the 200’s
I don’t want to add tartness
I find that all my Blondes come out as dirty blondes (no oxidation). I suspect it is because the PH is in the higher range. I am brewing another this weekend and want to try a lower PH and see what is does
Any hints suggestions or similar issues?
PS. I have brewed this 3 times and the PH calculations are fairly accurate.
