EZ Water Starting PH

[spreemotion]

Hi All:

I have searched up and down, hoping someone can help with a question or two I have about EZ water. I am currently using 100% RO water in my batches, but starting to focus more on the PH element. I just tested my RO water from the local store, and it is coming in @ 8.25.

In EZ water with just default 100%RO - EZ water with no additions it shows 5.70 PH, okay no problems, however how I can adjust that to match my starting RO PH of 8.25? I for the life of me cannot figure it out, any suggestions?

In actual use, and with regard to mash pH, your waters pH is virtually (if not totally) irrelevant to the internal workings of spreadsheet programs such as the one you reference (and most if not all others of its ilk), even if they ask you for it. The effect of the waters pH is clearly there, but it is essentially dwarfed by the effect of the waters alkalinity and the DI mash pH's of the various malts that comprise your grist bill. Once you have accounted for the pH shifting effects of the waters alkalinity and your beer recipes various malts and/or grains, the remaining effect of the strike waters starting pH is 'generally' trivial with respect to the final mash pH.

Where water pH as well as water alkalinity must be considered is in the acidification of sparge water. I'm not sure that EZ Water addresses sparge water pH.

Where most get confused is in associating alkalinity with water pH. In the brewing world alkalinity is the measure of the waters concentration of mainly MgCO3 and CaCO3, wherein both of these are conflated into CaCO3 for alkalinity reporting purposes on a water report. The units are most often expressed as ppm or mg/L (with these being interchangeable).

Bicarbonate concentration is another (pH dependent) means whereby to express waters alkalinity, and the relationship (rounded) is:
Alkalinity = 0.82 x Bicarbonate
Bicarbonate = Alkalinity / 0.82
