All Grain Brewing / Russian Imperial Stout Water Help
« on: March 17, 2010, 12:33:36 PM »
I just recently moved and have all new water to contend with. In addition this will be my first attempt of a stout so I'm looking into how to adjust my water. Any input would be helpful as I'm just starting to get into water chemistry. Here's what I came up with for a 3 gallon batch...

Starting Water (ppm):
Ca: 39
Mg: 6
Na: 71
Cl: 138
SO4: 9
CaCO3: 54

Mash / Sparge Vol (gal): 3.5 / 2
Dilution Rate: 0%

Adjustments (grams) Mash / Boil Kettle:
CaCO3: 3.5 / 0
CaSO4: 2.5 / 1.4
CaCl2: 0 / 0
MgSO4: 0 / 0
NaHCO3: 3 / 0
NaCl: 0 / 0
HCL Acid: 0 / 0
Lactic Acid: 0 / 0

Mash Water / Total water (ppm):
Ca: 188 / 149
Mg: 6 / 6
Na: 133 / 110
Cl: 138 / 138
SO4: 114 / 114
CaCO3: 319 / 222

RA (mash only): 181 (20 to 25 SRM)
Cl to SO4 (total water): 1.21 (Balanced)
