I understand that a good rule of thumb for brewing water is that if it tastes good it's good to use for brewing. Most of these nine springs that i've tried are way too mineraly to my taste but "7 Minute" and "Ute Chief" are really good and I'd like to at least use a bit of one to my brew water to add some depth to the beer. Aside from taste, will any of these minerals affect the yeast in a bad way? Or will this be simply an aesthetic change to the taste?
I guess I should add that I'm looking to brew a Double IPA.
