I have a Ward report on my water and it is as follows:
Na: 24 ppm
Ca: 60 ppm
Mg: 39 ppm
Sulfate (SO4-s): 15 on the report = 45 for brewing use
Cl: 21ppm
Bicarbonate: HCO3 333
Total Alkalinity CaCO3: 273
Total Hardness CaCO3: 313
pH: 7.8
I am brewing up a Belgian Golden ale, 12 gallons, with 27 lbs of grain and 5% of the grist is acid malt. This will be a sour beer base.
Now I am looking at Kaisers Water Calculator and using the advanced sheet i entered in my values above, and will be boiling the water the night before and letting the solids precipitate (correct wording?) out and siphon of the water. The calculator shows that the TA will go from 273 to -193. Also if I cut this water down with 50% RO the TA then goes to -255 and cuts the above minerals in half. The estimated pH is 5.2. I will add a couple of grams of CaCL, and some CaSO4 to the mix.
My question is, does anyone out there have any experience with this and how accurate is the new TA number? If the brew was further out I would boil a sample and send it to Ward for another analysis.
Also am I on the right track??
thanks in advance
