Brewer's Bread with Spent Grains

When I heard about breads made with spent grains - leftovers from beer brewing - I was fascinated.
How interesting! But, where on earth, could you come by those mashed grains, unless you worked at a brewery? We have two micro-breweries in Bar Harbor, so I left a message, asking whether I could purchase a small amount of their spent grains.
The sobering answer: the mash goes to the (dogs) hogs. All sold to pig farms - sorry!
