Post Carbon Fellow Wes Jackon was interviewed about Kernza and beer in the Modern Farmer.

From the article:

MF: The Land Institute has developed several perennial grains, of which Kernza is the first to become commercialized. How widely has it been planted?

WJ: It’s still very limited. So far much of the acreage is for research purposes, but there are farmers growing it up in southern Minnesota for Patagonia. Besides beer, Patagonia wants to make some other food products with it; I don’t know exactly what yet.
