Just finished some Bent Rod Rye - AG. I kept track of each of the runnings just for grins:
First 1.5 gal @ 1.078 117 points 46% of total
2nd 2.0 gal @ 1.037 74 points 30%
3rd 2.5 gal @ 1.024 62 points 24%
5.5 gallons into the fermenter @ 1.046 Efficiency 74%
So, if I had only done one sparge, I would have been at 56%.
