Back to water treatment. A subject dear to my heart. This time the brewery is Courage.
Interestingly, the section in the logs isn't entitled "water treatment" but "water hardening". Take a look:

Kainit is KMg(SO4)Cl•3H2O. I assume CC is calcium carbobnate. Salt is, well, salt (sodium chloride).
There's not a great deal of difference between the treatment for Porter/Double Stout and the X Mild. But I was slightly surprised at how much more of the Kainit was added to the KK.https://blogger.googleusercontent.com/tracker/5445569787371915337-3697255134965465622?l=barclayperkins.blogspot.com
