Title: Flaked oats crushed or not
Post by: wartotojas on April 16, 2017, 08:29:01 PM
Hi everyone,

I used to buy my grain kits crushed and got my hands on a mill recently so ordered my recipe kit uncrushed. Making some American wit that has 500g of flaked oats(aprox 12% of grain bill).

I was reading that flaked oats are ok to mash without milling. Since these are mixed will I be alright to run them through mill with rest of the grains?

Sorry if it's a noob question  :-[

They are fine as they are. Do not crush them as if you do you invite a stuck mash.

That's a thing flaked oats are mixed with rest of the grains :(

I actually grind oats all the time and have no issues. Makes it easier to get at the whole surface but does make things a little stickier. Go with a mash of 3L/kg thickness and it shouldn't stick.

Surely Shirley the flaked oats will pass through the mill rollers without any more damage?

They have already been through the mill!

I never bother milling anything flaked. like will I cant imagine most mills getting any purchase on them.
The more important question Flahavans or Odlums??

Mill away, they're mixed in with mash kits.
Consider conditioning your malt, no need for hulls.

So I milled everything and brew it on Tuesday as planned. Most of the oat flakes went through without being crushed. This was my 4th brew on braumeister and it was pumping through very slowly. But at the end I got 79% efficiency were previous brews were 80%. So happy enough. Will see how it will turn out after.

The slowness was probably due to the oats. As they are already flattened I would recommend to just put them into the crushed grains and mix them up before putting into the mash. Glad it all went well for ye. :)

Did you condition?

Nope, did not condition my malt.

As I said, only started milling myself recently so there is still stuff to learn
;D
