Will Double Crush Improve Efficiency?

[ultravista]

I mash in a fine mesh bag (voile), as such, don't worry about stuck sparges and I've been wondering if I could improve my extraction efficiency by double crushing the mashing grains.

Who here double crushes? What has it done for your efficiency? Typically, what can I epect as an improvement, in points?

If you are mashing in a bag, why not just tighten down the gap on your mill instead of double crushing?

I'd try it a few ways and look back at my notes to see which method worked best.

I tried to double crush one time and the once crushed grain didn't fall down into the mill.

+1 on setting your gap smaller.

I am not milling myself but can request it from the HBS. I'm thinking of trying it for a batch or two to see what results I get.

I BIAB and don't crush myself - and the (understandably) the LHBS won't adjust their gap - so I just get them to double crush - efficiency is better for me when they double-crush

Double milling bumped my mash efficiency from around 75% to 85%. Really was only variable that changed.

That's it, my next order will be double crushed. I've got a Double Dead Guy, Arrogant Bastard, and a Westy 12 in the pipeline.

If the gap on the mill is set correctly that eliminates the problem in the first place.
