There are plenty of threads on water chemistry in specifics, but I want to know, how many of you take the time to make mineral additions / pH adjustments?
I became confident it had some merit after noticing that the most statistically significant Brulosophy XBMT was one that focussed solely on water chemistry. Researching local Canberra water and plugging variables into Bru'n Water told me that my mash pH was too high (5.85), sulfate / calcium / chloride was too low etc. I now brew with modified water and results are good thus far but there's a good chance that is due to confirmation bias.
Any AHBers swear by (or swear against) water modification, and the extra effort it requires?
