Checking Graham's water treatment calculator

(That's water to the rest of us!) Beer is about 95% water, so if you want to discuss water treatment, filtering etc this is the place to do it!

Checking Graham's water treatment calculator

Post by guypettigrew » Thu Nov 02, 2023 3:06 pm

Just setting up for a brew day tomorrow.

Looking at GW's water treatment calculator it has a ratio of 8:1, sulphate:chloride for a Burton pale ale. Aside from the fact my water can't achieve this, is this ratio right? Seems incredibly high in sulphate.

Thanks.

For what it’s worth I use Graham’s water treatment for Burton pale ale for a draught Bass clone. The main difference in the treatment is the addition of far more Magnesium sulphate than if I were treating water for bitters or pale ales.
I accept that my water profile is maybe a lot different to yours. The end result is a good copy, so there must be some strength to the calculation. I think it’s over to Eric!

The following is taken from Brewing Science and Practice by Herbert Lloyd-Hind late 1940's edition.
The analysis is similar to that done by Edmund Southby circa 1880 though not necessarily the same analysis.
Multiply parts per 100,000 by 10 for ppm

Sulphate to chloride is a lot more than 8 : 1 so just go with GW's calculator.
