I am sure this has been discussed in previouse threads, but I was curious what kinds of water testing methods/tools/kits most of you are using for your water profile management. I am at a point where I'm ready to really get into the chemistry side of brewing and I am eager to start balancing water profiles. I have used mostly bottled spring water for my brews with success, but I would like to start conditioning my water profiles closer to style guidelines. How are most of you doing this? Is is it testing then adding brew salts, etc.? If so, what methods are you folks using to test and measure water alkalinity/pH? Thanks!
