I've asked this before without any helpful replies. It would be great if someone could go in and try what I'm talking about and see what happens. Here goes: I put in a recipe in the recipe builder. I then go to build water in the advanced water calculator, importing the recipe I just created. In the water calculator it will have the ingredients of the recipe listed. Say the color comes out at 15 SRM and for what ever I've added to the water say it gives me a mash pH of 5.5. HERE'S the problem: go to the grist info and switch it to beer color and put the info in there. 15 for color, etc. Then my mash pH will drop to 5.2. WHY??? It does this consistently and it drives me nuts. Which one can I trust?
