Hey all, just got my results back and they're somewhat encouraging. I haven't tried to brew with this water yet, I just moved here, but I plan on working on water next in my long list of things to "improve" my beer. I read the Bru'n Water - Water Knowledge page, whew, that's a LOT of information. Here's the results:
pH - 7.8
Sodium, Na - 70 ppm
Potassium, K - 1 ppm
Calcium, Ca - 28 ppm
Magnesium, Mg - <1 ppm
Total Hardness, CaCo3 - 74 ppm
Sulfate, SO4-S - <1 ppm
Chloride, Cl - 17 ppm
Carbonate, CO3 - <1 ppm
Bicarbonate, HCO3 - 261 ppm (eek)
Total Alkalinity, CaCO3 - 214 ppm
Using the formula on Bru'n Water, I calculate my Residual Alkalinity at around 206, which is pretty high as I understand it. It appears that my water will be better suited for stouts without significant additions. Am I understanding that correctly? The remaining minerals seem to be in relatively good quantities I think.
My utility report says that there is approximately 2.37ppm Chloramines in the water from their test. So I'll definitely need to invest in Campden Tablets to get rid of that (although the smell test didn't work for me...I don't smell chlorine at all straight out of the tap).
What do you guys think?
