So ever since I moved to AG my efficiency has been sh*t. Never above 70%, and today with my dubbel I hit an amazing 64%! wtf??? this is pissing me off because im not doing anything wrong. Im even mashing for 90-minutes now because of it. my mlt is solid, im hitting my temp's, especially my mash. My sparge is always sort of a ballpark figure as I only collect as much as I need per mash runnings. The only thing I can think of is that im not crushing my own grain. . . i do it as my LHBS so maybe its not fine enough. HELP

A better grain crush is what did it for me. I went from 60 to 82. Maybe your water pH is different?

Ph can make a difference but crush seems to be the most important thing. I recently bought a barley crusher (only 2 batches ago) my efficiency went from a stable 70% (across 10 batches) to 80% on the first try then to 87% after adjusting the gap on my mill.

1. the crush. 2. pH can make a difference. Since you tried 90 minute mashes, refer to point 1. Try running the grain through the mill twice. If the efficiency improves, you'll just HAVE to buy your own barley crusher.

I wish I could come brew with you on your system using your ingredients. If efficiency still sucks, it's the crush or your water. If it's good, it's your process.

I'm suffering from the same thing as you, and having examined every step of my process at the microscopic level, I'm convinced crush is the main culprit. I tried Ph 5.2, and it makes no noticeable difference. Moving from my LHBS mill, to my own Corona (free) has improved things a little, but I deffinately see a barley crusher on my horizon.

Tell us where you're at and maybe one of us is close and can help you out.

If you want we could try something. Send me your grain, I'll run it thru my mill and ship it back to you (depending on how far away you are). I hit 85-87% every time.

I have to say I feel your pain. I'm finally up to around 73%. YEEAAA.
PH issue first - I have had a cheapo PH test system for a while to use on meads that I have never bothered with using, tomorrow I will test it but it's so cheap I don't know if I will trust any reading.

Crush, I asked the HB store to narrow the gap down to 41, (It was up to 55+). Got me from the low 60's to the 70's. Moving two batch sparges and to around 190F sparging temperature has helped also.

Waiting 10 minutes from adding sparge and stirring may have helped me.

Someday I might hit 80%, but until then I just adjust the base 2 row to adjust for my piss poor performance.

Best of luck. Brew On.
