Has anyone noticed recently that the Grainfather on-line site is giving odd values for strike water? Normally the mash has a porridge like consistency. Today I did a brew and just blindly followed the value for my strike water. It was very runny and I achieved a gravity of 1.038 (target 1.050). My fault, that I should have double checked the values. I have the mash thickness set to 2.75 L/kg. With a 6.1kg grain bill it should be 16.1L, but grainfather is telling me to add 20.27L strike water. Any other grainfather users noticed this?
