Hey Brewer Friends, I have been banging my head against the wall for a while trying to solve a problem with inaccurate and inconsistent water volume calcs and in turn, predicted gravities. I am now wondering if it is my hop absorption rate. I have it set to the default .15 qt/oz in my profile. I also have 1 qt dead space in my kettle. I just throw loose pellets into the kettle and after whirlpooling they settle into the dead space. So I'm thinking that I am double dipping on the deductions. Yes, I am losing the 1 qt in the dead space, but I am not also losing an additional .15 qt/oz of hops I use. Does this make sense? If so, it would explain why the variances I see are never consistent - because it is tied to whatever amount of hops the recipe calls for. Should I keep the dead space number and set hop absorption to 0.
