Looking for some advice here. I charcoal filter my tap water which comes from wells in Chino Ca. It's great water for brewing dark to amber beers. Even with a big Russian imperial stout my mash ph will hit 5.2 to 5.3 with no additions. I usually just brew what works with my water but I'm getting tired of keg after keg of stout and Porter or dark mild. I don't really want to get in to messing with my water chemistry. Is acid malt my only option if I'm not going to pay more money for distilled water? Any ideas on simple affordable ways to brew pale ales IPA or Belgian ales with the water I have?
