Um, don't think so. According to some articles the only way to get a high ph (anything over neutral) is if the water has a lot of minerals in it. That's why the expensive machines also have a setting for dropping in liquid minerals so that as the water makes the ph it stays.
Best CS is made when there's very little of anything in the water. So I have to wonder if adding minerals to water to get and stabilize the higher ph, if that would exclude good CS. Maybe I'll ask this on Mike's silver list. It's a good question. Samala, Renee Anyhow, I suppose one could run DW through an alkalizer and then use that to brew CS.
