Thought I'd share the next process improvements with you for comment: - Adding an activated charcoal filter (removable) to my water supply. Now that I have water in my basement and don't have to go to the outside hose bib for it, I'm getting an in-line filter, the kind RV owners use to filter the water going into their system. Our water is not excessively chlorinated but there are (1-2) ppm chloramine and 20-200 ppm chlorine. Explains the occasional faint hint of chlorophenols I get, not every time, but sometimes. I'm controlling for variance now - the process is consistent enough I get good results every time. - Acidifying sparge water to control occasional, slight astringency and cloudiness in my beers. Our water is normally about 7.8 pH but control of the process, where possible, makes for consistent beer. I'll acidify to 5.4-5.6, using the mash water calculator as my guide, again as control of variance in the water supply. Thoughts?
