I got a real puzzling question. Thanks in advance for any help... today I took a shot at a baltic porter. 21 pounds grain bill and it SHOULD have yielded an og in the high 1.080's at least, but I'm lucky to have gotten 074 and that was continuing my boil from 60 min to 105 min. I collected about 8 gallons of wort and took it down to about 5-5.5 gallons. Mashed for 1 hour at 153. Is it possible that I sparged too much, diluting the wort??
