Yes to the above! Also if the wort is stratified with a higher concentration of sugar, the absorbed wort within the grain is also at a higher concentration.
Stirring well twice is a good thing IME.

Glad you are progressing. This thread should be retitled, "Efficiency problems w/ Monster Mill Slotted Helical Rollers"
I'm a little disappointed MM didn't rectify the situation promptly, and yet charged you shipping to sub the rollers on a $400 purchase. doesn't sit well with me....jmo
Cheers!
Ps The Captain Crush went the way of the dinosaur, maybe this will also unless they retool.
Two roller monster mill set at .035 , my efficiency routinely approaches 80%
That's an awfully nice looking piece of furniture for mill table....
I did get my mill table finished, and am very happy with how that turned out. On a positive note, the service from All American Ale Works was absolutely fantastic when I had a few questions about their PowerGrinder motor I am using on the table.
I dropped the mill gap to 0.025" and should have a chance to brew another batch in a few days.
Your conversion efficiency, pre-boil efficiency, or brewhouse efficiency?
- Brewer's Friend appears to have corrected the conversion efficiency calculation in their Brew Session tool. Their brewhouse efficiency calculator still reports a different result. For batch #1 I calculated a conversion efficiency of 90.7% using Braukaiser's formula. Brewer's Friend's Brew Session tool reports 91% conversion efficiency. Their brewhouse efficiency calculator reports 83% with the same inputs.

You say you have a hydro measuring degrees Brix (°Bx). What's wrong with using this PDF table?

That table, mill, machined bottom plate, motor, everything belongs in your parlor, not the brewhouse!
The 0.025" gap on 2" rollers should give you the best BIAB crush there is. Even wheat and rye will be crushed to perfection!
@Epos7,
Brix = Plato out to like 6 or 7 significant digits. The conversion factor of 1.04 quoted by Kai is either A) wrong or B) misunderstood. In either case, ignore it because 12.0000 Brix = 12.0000 Plato (for example).
As I understand it, the correction factor of 1.04 that Sean Terrill uses is based on an average correction factor from numerous different brewers, but is specific to each individual refractometer. My own refract. seems to be the opposite with a factor less than 1.000, maybe 0.94 or thereabouts. More experiments are needed. If you want to know the factor for your own refractometer, you'll need to measure Brix simultaneous with a calibrated hydrometer and compare readings over numerous batches to come up with your own average, which may be 1.04 or may be something completely different.
As far as I know, Brewer's Friend's calculator is doing things right from what I can tell, assuming you know the WCF to put in to give you accurate results.
My understanding is that Brix = Plato specifically for sucrose solutions. Wort is not a sucrose solution, so has a slightly different index of refraction. So, you need a wort correction factor to adjust for that index of refraction difference, in order to get more accurate SG measurements.
Brew on

Yeah, your refrac is near 1 like mine. I use the Plato to SG part of Kia's table for my refrac and short range Brix hydros
This is a nice online calculator with the formulas they use and a table; http://www.straighttothepint.com/specific-gravity-brix-plato-conversion-calculators/
Just wanted to post an update. I brewed a batch yesterday where I dropped my mill gap to 0.015". Previously I had it set to 0.020". My conversion efficiency jumped to over 97%. With a gap of 0.020" I was anywhere from 88-93%. I also noticed dough balls for the first time.
I'd say I've finally hit the sweet spot
A stiff wire whisk annihilates doughballs.:rockin:
Yeah, I may have to look into one of those comically large whisks. I have a homemade mash paddle that works fairly well, but I think the whisk would be better.
