I don't know how to understand, evaluate and adjust my city water for brewing but I starting to come to conclusion that my city water is a little hard. If I use 100% tap water my brews become really bitter even with just 20-30 IBUs if I mix it with 80% RO water I usually get good results, smooth beers and hops take a back seat. Its good for some styles and not so for others. Can you please lead me in right direction, how is my water and what should I do? What proportions I should mix it with RO? Would 5.2 ph stabilizer be a good idea in my mash? Thanks.
