Water Profile Help

[maltoftheearth]

I ordered a water profile from Ward Labs and received the results below. My biggest concerns are a higher than average pH and low magnesium (good for yeast health I believe.). Are these valid concerns? What else should concern me? Any suggestions for modifying this profile? Thanks in advance for suggestions.


Water Profile

7.5 pH
68 Total dissolved solids, est (ppm)
.11 Electrical conductivity (mmho/cm)
.9/.8 Cations/Anions (me/L)

6 Sodium (Na)
1 Potassium (K)
11 Calcium (Ca)
<1 Magnesium (Mg)
32 Total hardness (CaCO3)
.1 Nitrate (NO3-N)
1 Sulfate (SO4-S)
<1 Carbonate (CO3)
22 Bicarbonate (HCO3)
18 Total Alkalinity (CaCO3)
.79 Total Phosphorous (P)
.2 Total Iron (Fe)

It's a continuing mystery why members have so much trouble finding it but there is a wealth of brewing water information here at HBT in the Brew Science section. https://www.homebrewtalk.com/f128/

Magnesium is of little concern and there is enough in the malt to supply the trace amounts required. Your water is soft, low in both minerals and alkalinity making it a good starting point. It is the pH of the mash, not your starting water, that is important. Many detailed discussions and answers will be found in the Brew Science section.
