I received my water report recently. For most of the mainly base malt beers I've been brewing I've only made some slight tweaks. I'm planning a Belgian Stout though and Bru'n Water is telling me to make what seem like big league additions and I'm not sure I've got this figured out. Here's the water report:
pH 8.4
Total Dissolved Solids (TDS) Est, ppm 95
Electrical Conductivity, mmho/cm 0.16
Cations / Anions, me/L 1.4 / 1.5
ppm
Sodium, Na 5
Potassium, K 15
Calcium, Ca 13
Magnesium, Mg 1
Total Hardness, CaCO3 37
Nitrate, NO3-N 0.7 (SAFE)
Sulfate, SO4-S 4
Chloride, Cl 8
Carbonate, CO3 6
Bicarbonate, HCO3 47
Total Alkalinity, CaCO3 49
Total Phosphorus, P 0.29
Total Iron, Fe 0.18
My Grain Bill (3.5 gallon batch, 3.25 gallon mash water volume) is:
7.5lb Pilsner
12oz Torrified wheat
8.5oz Flaked Oats
14oz Chocolate Malt
5.5oz Black Patent
5.5oz Roaster Barley
I tried the following additions to the mash water:
0.4 g/gallon Gypsum
1.25 g/gallon Baking Soda
0.25 g/gallon Calcium Chloride
1.25 g/gallon Chalk
Which gets me to an estimated mash pH of 5.3 but my Alkalinity is off the chart (579).
Does this sound OK? Also, do you usually throw in the additives as per the spreadsheet or do you use that as a rough guide and adjust until the pH is right?
Thanks for any help
