Last night, Denny mentioned that you get the best efficiency in batch sparging if your first wort and the 2nd running are the same volume. Why is that?
Do me it sounds that you get better efficiency when you do more spargings since there will be sugars left in the grain after the 2nd running. Though that may not be desired since your mash PH will sink and you will have to much wort to boil-off, I wondering about his statement since he mentioned it is a theoretical maxium?
Could it be the maximum for only 2 run-offs?
