Ok, so ever since I've brewed AG, I've always had 70-75% efficiency. Anymore I'm always dead on 71%. I've been ok with this as it really doesn't effect my beer, but I figured I should change it.
So today when I brewed a hefe I took gravity samples every .5 gallon. I though the results were interesting.
First runnings (each number representing a half gallon):
1.085
1.082
1.066
1.065
Now I batch sparge(rubbermaid cooler and SS braid) and here is where the first 2 gallons of hot water was added:
1.030 (notice the massive drop)
1.027
1.024
1.018
Second 2.5 gallons:
1.018
1.017
1.017
1.016
1.016
Recipe was 4lbs german pils, 4lbs wheat, 2lbs honey malt. Mash at 1.33 qt/lb Sparge 1.6qt/lb 175*F water. Single infusion at 155.
So I'm looking at that and it seems there was sufficient conversion and the first running were spot on where they should be. Now on the sparge of the first hot liquor addition, the points drop through the floor so there has to be something wrong with my sparge technique. I pour in the 2 gallons, stir really well, let it sit a few minutes and drain. The only thing I can think of is, let it sit longer and then drain slower.
Anyone want to look at those numbers and conclude something different?
