Yeah, my water is really good. Back when I was trying out different bottled waters, my own water was continually the best. It was closest to VOSS, but I personally like my own water better. And yeah, I live about 35 minutes east of Seattle, in the Cascade foothills.
Perhaps I'm being too much of a simpleton when it comes to water, but honestly I usually just fill my Zojirushi with the artesian spring water that I normally drink. Usually either Kentwood, Abita Springs or Ozarka.
I don't think it's as complicated as we are making it out to be, lol. It's seems like one of those things that is not a problems, unless it's a problem. I never realized I had a problem until I spent 2 months in Germany. When I returned, I realized my filtered tap water was killing my teas. Searching for a solution sent me down a rabbit hole.
