I have done about 15 or 16 all grain batches and was getting about 60-65% efficiency with pre-milled grain. I recently bought a Barley Crusher and was able to get 75% on the factory setting during my last 2 batches. On this last batch I narrowed the gap a bit. I didn't measure the gap but turned the adjustment knob to 1 o'clock on one side and 11 o'clock on the other. The grind was a lot finer but most of the husks were still intact so I decided to give it a go.
I use a SS braid in the bottom of a 10 gal round cooler and did not even have a hint of a stuck sparge. I used a double batch sparge. I couldn't believe the hydro reading, 87% efficiency. The recipe was calculated for 75% so it was way higher than I expected.
Now the trick is to se if I can do it again to prove that this was not a fluke.
