I am following the instructions for AHB Pliny the Elder - All Grain recipe. After mashing the grains, the following statement appears "Don't run off more than 6.25 gallons of wort!" I thought this made sense if the boil off volume left you with 5 gallons+ of beer. However, this proved not to be the case when I later read in the instructions "add cool water to make 5.5 gallons".
This seemingly contradiction caused me to appeal to all of you far more experienced and smarter than I am to understand why I would stop the mash run off if I am only adding water on the back end.
Any thoughts would be appreciated.
