I'm using well water that I know has pretty high calcium. I would like to get a test but I also suspect that the composition changes seasonally so I feel that will not be the last word on things.
I've been reading up on how important pH is and I'm confused on one point - I hit my target SG at 1.064 with no problem, but everything I'm reading says that a too-high pH in the strike/mash water (this is a BIAB remember) will result in a lower efficiency.
I know pH can be an issue, but I'd like to be mindful of any other causes of this tannic bitterness. Could my temps have gotten too high? Could I have squeezed tannins out of the grains in the mesh bag unintentionally?
I really appreciate all of you guys taking the time to share your thoughts!
PS - The distilled water issue: I actually tried to buy a gallon of distilled water for my steam iron at my local box store (Meijer), but they had nothing of the sort and no empty shelf where distilled water might have been. Very baffling!
