Good Setting For Grain Mill

[pingeyeg]

I've recently purchased a power drill for use on my grain mill, which works great, but I've also noticed my OG has been well over my target.

Estimated - 1.063
Actual - 1.083 (+.020)

I have to assume it has to do with the setting on my grain mill when using a power drill. Does anyone have any advice on what they have experienced in setting the mill grinders separation? Some grains are smaller than others so trying to find a happy medium.

Are you using BIAB or a mash tun with false bottom? A higher efficiency can be a good thing if you aren't getting stuck sparges. What is your efficiency when milling with power drill vs. hand crank?

To be honest, I really don't know what my efficiency is nor do I know how to calculate it. I've read a few articles on it, but seems like it was more complicated than needed. I use a mash tun with a SS bazooka screen.

I condition my grain and use .025 on my JSP malt mill.

Well if you're achieving higher than expected O.G. then your efficiency is higher than your recipes are calculated for. This can be a great thing because it can save you a couple bucks per batch in grain. So, calculate your efficiency. Use an online calculator or do the math yourself.

Adjust your recipes to the efficiency you've been getting, which would mean less grain, or widen your grain mill gap a few millimeters for a courser grind until you hit the numbers you've been expecting.

When I do wheat or rye, grains w/o husks--.025. All other grain--.035
