I ended up with 10 gals of 1.055 B-52 wort in the fermenters and 1/2 gal in kettle. Using promash this 10.5gals at this OG only yields 63%..I feel like that is a D grade and was thinking I am a B type guy?
My mash temps were about 4 degrees low at 150. could this explain some?
Another problem I had was in reaching my mash out temps... Adding the 9.5 qts of 200 degree water didn't take my mash anywhere near 168?

I don't see hwo either of those could affect your efficiency that much. Was your crush different than usual? Anything else?

Its all in the crush. I've been tweaking my Phil Mill recently until I tightened it so much I broke the nut. I've seen my eff. go from 70%, to 78%, to 93% (when I broke it) over the last two batches after cranking up the nut.

I only added 3 of the 4 lbs of honey. I had a bad trip on B52 last spring so I figured a little less alc was ok with me. I had the same LHBS crush the grain but I thought the crush looked more coarse.... I guess I will add a mill to the xmas list...I also ended up with .9 gals in the kettle and I just reread my OG reading and get a room temp of 1.056 which corrects to 1.058 so my eff might be closer to 70%..

Not efficiency related but I also had a real problem with the drain on the kettle...My 12" of SS hose got clogged and I had to use the auto sipon..Only thing I did different was to drain off 1 gal of wort during the boil to make sure the inside of the valve was sanitized...
Ive got to get a CFC because waiting for the wort to cool using my IC is like a long 40 minutes even with winter tap temps. Add on holding the auto siphon off the bottom for 10 gals and I am ready to order some equipment tonight from B3.

Since you were using ProMash, what was your batch size set to? 10 gallons? Or 10.9? I find that the actual size of the batch has a huge effect on efficiency calculations, so that could make all the difference. I also calculate efficiency based on pre-boil gravity reading, but ProMash may do it differently.

It looks like 70% is what I achieved which is not as bad as 63%...I will work on the crush and conrrect temps for next weeks batch.

Well I just checked on my 2 carboys and 9 hours after pitching I have 2 bubbles per second!
And guess who I thought of? Fredrik. I can sleep well knowing the yeast are finishing my brew.

B-52 has alot of hops and if your using whole hops there is alot of wort trapped there . It would throw your calculation off considerably . This is why I use preboil volume to figure my mash eff. , What you figured was your system eff.

B-52 has a lot of hops like Bud has a lot of hops

Was that Doug being sarcastic?! Wow, I have to mark this page for historical reference... :)

You should pick up a point or two if you can raise the grain bed to 165-170 for sparge as well.
