Double crushing grains

[richfei]

Bought a cereal killer grain mill some time ago but will use it later this week
Read that it's worth changing the setting to around 0.036
I've done that
Is it still worth double crushing the grains for BIAB ?

Do a single crush and see what you have. There should be few to no whole grains and the husks should be split but intact. If you get that on the first run you're good. If not crush it again. I don't own a mill so I crush at the LHBS a day or 2 before brew day. When I first started I ran it twice. Then apparently the LHBS adjusted their mill and now the second run is unnecessary.

Since you do BIAB you can crush it finer to get more efficiency.

I have a cereal killer as well. I need to get a separate low torque drill. I just used my craftsman 18v and had it churning slow but it was pulverizing the grain. :-/ Still ended up ok in the end.
