Hey guys...I'm doing an AG batch and using a recipe from Austin HB that called for a 5 gallon sparge. The first runnings into the kettle totaled 2.25 gallons. I followed the sparge instructions and only pulled 4 gallons of wort to total 6.25 gallons into the kettle. The question I have is there was still 1 gallon of 1.020 SG wort left in the mash tun...is there a reason why I shouldn't just add this to my boil? And then just boil down to 5.25 gallons? The recipe seemed very adamant about not going above 6.25 gallons.
