If your volume is high by 1.5 gallons or more, you are certainly mashing and/or sparging too much obviously. It is likely you are extracting tannins someplace or other. What is your mash pH? And what is your sparge pH? If you don't know, that would be part of the problem. I'm pretty sure this is a pH issue. You don't want your pH going over about 5.6 during mash or sparge. Sparge pH is probably the real problem, but could it be that you are just using really alkaline water from the get-go?
