The SO4/CL ratio descriptors were taken from John Palmer's spreadsheet. I don't really believe in them either but lots of people are looking for this feature.
Looking forward to experimenting with another water tool! Like the IBU formulae, I like trying to find a 'window' of expected IBU or mash pH.

I think the SO4/Cl metric is a bit overblown. That said, I like to separate sparge and mash water for darker beers. BrunWater's option to adjust sparge additions is great to maintain the Ca level, while keeping SO4/Cl in the ballpark when removing chalk and lime in the sparge liquor.

Really like this Kai, thank you! I hope this is what I can use from now on to get rid of the several sheets of scratch paper of frantic calculations that seem to form the night before every brew day.
I already see a few tweaks to my strike/sparge water on my sweet stout. I was in the ballpark, but this tool will get me on the pitcher's mound!
I entered all the information from my last brew day and your predicted mash pH was spot on to my actual readings with my Milwaukee 101 pH meter.

Thanks, Jason. I'm glad the pH prediction works for you.

We just released a new version that has a few bug fixes but also adds the capability to save the current input values into a record that can be accessed trough an encoded link.

More feedback: I brewed again this weekend, your program predicted a 5.42 mash pH but it ended up 5.39 in real life. WAY off!
J/K... loving this new tool! Again, thanks for sharing.

Thanks. Maybe I have to use quantum mechanics to implement a prediction that gets closer to your actual measurement.

I just tried it this weekend and it worked beautifully. It was very easy to use and yet also had everything I needed. This will be my go to calculator now. Thanks.

We just released version 1.3 which has a few notable enhancements:

- option to show overall water and mash pH at the bottom of each section. That will reduce the scrolling needed when you try to match a profile or mash pH.
- support for CRS/AMS, which is a HCL/H2SO4 mix used by our UK brewing friends
- support for malt pH parameter entry as DI water pH or acdidity in mEq/kg. That's for folks who know these parameters.

We are working hard on the integration into the recipe editor but want this to work well and intuitively. That's why its taking its time.

Wow, I plugged in the data from my last few brews and the predicted pH was really really close (well within the margin of error). Question, do I enter amber malts, biscuit, aromatic, brown as base malts or roasted malts?

I would enter them as roasted malts.
