Jeff--have the programs and have diluted with distilled, just not quite the clean outcome I want. I'll keep reading and "playing" (AKA brewing). Palmer's RA spreadsheet is the one I've been using over the last year + and that has gotten me much closer, a noticeable improvement. Maybe I'll have to get some more tips from AABG! With your water source being Village well, I see why you're using RO and building from there. Our City water makes fantastic light ambers to stouts with minimal adjustments (OK, so there are some advantages to living in metro Detroit).
