They make good beer, it is what I usually drink. With all the oil in alaska, amazing that burning grain makes sense.
But then, the EPA does not make sense, it is the cause of the problem, not the Brewery.
Burning oil for heat energy rarely makes economic sense anywhere in the world, unless you have no other sources of fuel.
It is the reason they shut down refinery units at North Pole, Alaska. It is tough to compete burning oil for power and heat when your competition in other locations us burning Natural Gas at about 1/6th the cost.
The grain burned in this brewery is waste product from the leftovers of making beer. There are not enough farms in the area to consume what they produce. They were spending too much money to dry it and ship it to the lower 48 to cover the costs.
