I'm brewing a small batch of robust porter (2'ish gallons)... if I plug my grist into E-Z water calculator, with no salt additions of any kind, it gives me a room temp mash pH of 5.63 (references optimal as being between 5.4-5.6). This is using plain old distilled water.
The grist is:
4.75 lb Marris Otter (80%)
0.38 lb rolled oats (6.3%)
0.25 lb Crystal 60L (4.2%)
0.50 lb Chocolate Malt (8.4%)
0.06 lb Black Patent (1%)
The minerals I would plan to add in are Ca, Cl, SO4.
Adding enough CaCl2 and CaSO4 to get the following levels brings my mash pH down to 5.58 (and residual alkalinity of -77)
Ca: 97
Cl: 113
SO4: 82
Obviously I don't want to make the pH go up any higher, so I don't need to add carbonates, right? Basically, the water would be completely carbonate free. Is that ok in this situation?
Thanks and Cheers
Steve
