The grain drying building. After distillation the remaining "spent grain" is dried and sold as cattle feed. It is actually higher in nutrients than the raw grain that arrives at the distillery.
These huge steel drums are rotating and drying the grain, similar to a clothes dryer.
Greg calls the drying plant the "tail that wags the dog" since it dictates the throughput of the entire distillery.
For instance, when Barton is distilling rye whiskey it tends to clog up the drying equipment. Since the drying plant efficiency is reduced they must slow down the entire distilling operation to match.
