It's a local mill here in upstate NY, McDowell & Walker, sell MilkeyWay feeds, they're 'out of this world!' Lol.
They have store I get it from.
Used to get it from a different mill, was pretty neat had to pick it up from the actual mill right next to the railroad tracks that delivered the grain...
I get layer 17% layer mash from a local mill for $10 for 50lbs. There is all sorts of stuff in it, you see some whole grains and legumes. And I ferment it except in the winter.
