I got 87% efficiency this weekend

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.

Congrats, that is a very good number, now like you said try it again to see of you can repeat it, it sure is nice to have ALL control over your crush, good luck on your next batch.

I am definitely adjusting my BC now...

Is there a way to calc your your efficiency? How do you know what your % is?

Cheers

Very nice, congrats. I have my system dialed in to 70% and have yet to adjust my BC. I tried it once, on a Rye IPA. That wasn't the best idea I ever had. The rye was like cement and I got my first ever stuck sparge. I've been scared to try it again ever since. One day I may get the cahones to try and make the same adjustment as you, but I will NEVER crush rye on anything other than factory settings again!

Brewing software such as BeerSmith and ProMash are wonderful. They make doing these calculations a snap and really are helpful when designing recipes. There are also a number of other useful tools as well. A soild investment in my opinion.

I've never adjusted my crusher and routinely get 90%. It might be the watter.

Conroe, what mill do you use? I currently get mine pre-milled from AHB, but would like to move to crushing my own soon.

The Barley Crusher. It's so much better than any precrushed grain I ever bought. I do deal with some stuck sparges though.

Rice hulls, my friend, Rice Hulls. I'm given to understand that a beta-glucan rest at 95F can help with lautering rye-heavy grain bills. So far, I've gone with as much as 25% rye without rice hulls, but normally I use the hulls, just for peace of mind.
