So I am a partial mash brewer. My house water is awful so I have switched to 100% distilled water and my brews have tasted better except for my IPAs. I usually add 1 teaspoon of gypsum when I add the steeping grains. I was wondering if someone can help me figure out if I need more additives or if it is just my hops and hop schedule that I need to change. Thanks in advance.
