Efficiency test

It’s always entertaining to see a thread take on a life of it’s own and witness varying opinions on a subject.  At least things remain civil on this forum, unlike other platforms, as we are only talking about beer.
After disassembling my new barley crusher I discovered the root of my problem.  The passive roller was up against the o-ring of the active roller, making it difficult for the passive roller to turn and help pull the grain thru.  I adjusted this, and milled my 11.5 lbs of grain and was happy with the crush.
I ended up brewing 5.5 gallons of a Marzen with an OG of 1.057.  75% efficiency for my BIAB method which I was pleased with.  Hopefully my next couple brews will be in the same efficiency range so I can proceed with confidence when creating future recipes…
Thanks for the input and entertainment.

Actually, the manufacturers directions tell us that the “O”-Ring is only in place for shipping and will eventually break and fall out.  So, it’s actually not necessary. Mine stayed in place for about 3 uses, then it was gone.

Good to know.  Wish mine had broken off sooner

I’m 3 batches in with a new grain mill and have had to make some adjustments.  My efficiencies with this mill have been all over the place.  I’m thinking of taking 1 lb. of 2-row and doing a test mash to see what type of extraction efficiency I get.  I’m curious if anyone has experience doing this and if I can expect similar efficiency when I scale it up to my normal 10-15 lb. batches…

One thing you could do is use your refractometer to take readings during the mash at intervals and record the extract you are getting. Then compare the first wort extract you are estimating to what you are getting. Keep in mind that first wort extract is the number that is going to tell you where you are at WRT the variables like crush, etc.

You may find that your conversion/extraction efficiency is lower or higher than you expected and adjust accordingly. This will help dial in the ideal crush for your system.
