So I have quite a few brews under my belt now but have a consistent issue with a salty bitter aftertaste. After racking my brain, scouring though palmers how to brew I'm starting to think its my water. I have a water softener and I've been reading that this will not be helping the mash process ( I do partial mash). What would be the best way to try an alternative water source. Should I use all bottled water from the grocery store and see how that goes or mix 50/50? I don't understand a lot of the technical water talk. I do have access to a ppm tester as well as ph tester. Would these help and what kind of numbers am I shooting for. Brewing mostly IPA or lighter style beers. The salty bitter is more noticeable with the lighter styles.
