Craft breweries occupy a special place in our customer roster because they have a unique problem: they have an enormous number of empty bulk containers and an enormous demand for full ones, and the timing of those two flows almost never lines up. Hop bags arrive in 50-lb sacks. Specialty malt arrives in 55-lb sacks. Base malt arrives in 1-ton supersacks or in bulk silo trucks. After a brew day you have a stack of empty bags, an empty supersack, and a couple thousand pounds of spent grain that needs to leave the building before it sours.
The traditional setup.
For most breweries the answer to spent grain is a local farmer with a livestock operation. The farmer drops off a totebox or a gaylord, the brewer fills it, the farmer comes back the next morning, and a hundred dollars a month changes hands. It works, but it depends on the farmer having a working truck and a flexible schedule.
Where we come in.
Some breweries have outgrown the farmer model. They produce too much spent grain, the farmer cannot keep up, and the gaylords pile up by the loading dock. We come in two days a week, swap the full bins for empty graded gaylords, and the brewery pays us a per-bin fee that is actually less than the farmer-with-pickup-truck model on a per-pound basis. The bins go to a livestock consolidator, the empties come back to us, and the cycle repeats.
Why this works for us.
Spent grain is heavy and consistent. The same 40×48×40 doublewall gaylord can handle it for 4-6 trips before the bottom needs replacement. The fixed timing of brew days means our trucks are not waiting around for variable pickups — we know exactly when to show up. And the price per trip is high enough that it pencils on the freight side.
The number.
We move about 280 spent-grain gaylords per month for Front Range breweries. That is 84,000 lbs of spent grain per week — enough to feed a couple of dairy operations. The same gaylords come back to us, get inspected, retaped, and re-routed to whichever brewery has the next pickup on the schedule.
