Default Hows my crush?

What do you guys think? Using a barley crusher.

Your image is too small and too zoomed out to see anything. It looks like your husks are shredded, but it's tough to tell from here.

That looks like a very fine crush. You could run into issues with lautering. Especially is you use a bunch of wheat in the grist. On the bright side you should get very high mash efficiency.

Do the malt conditioning technique with that and you will be a happy brewer. 2% water by weight sprayed and mixed into grains, let the surface dry off (some do a few minutes, I prefer longer) and mill.

I would think with that crush you will get a lot of husk tannin in your flavor profile and quite a bit of flour on the bottom of your brew pot. I would back off a little on the plates. You want the grain to be cracked, but the husks pretty much intact.

That looks exactly like my crush. I have my barley crusher turned to about the 2:00 position. Never had a problem with lautering and 80% efficiency every time. But the only few batches I have done with the new crusher are in the fermentors so no word yet on "husk tannins" but I have never had a problem with that before.

PS where in VA are you located?

crush is just one factor in tannin extraction. Sparge method, temp, pH, gravity all come into play.

Also if you find you do have issues with lautering, a few handfuls of rice hulls go a long way!
