Mill Gap for BIAB (Efficiency Problems)

[doug293cz]

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/

The problem I have with the linked page is that it says the equations for converting Brix to SG and Plato to SG are exactly the same (except for the ordering of terms), but the equations for converting SG to Brix and SG to Plato are different. That makes no sense.

Brew on

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.

I'd try a small one first. The doughballs, being dry in the center, tend to float to the top. Break up the ones on top so the next in line can float.
