From the open vats, the slurry is then pumped to a 5-story tall copper distillation column. This is where the 12% alcohol slurry is distilled to a higher concentration. The distillation column sits to the right of the tanks in the photo above. Most of it is out of sight as it goes up through the floors of the Still House.
The distilled liquor is further refined and the proper amount of water is added to reach the final "proof" for the fresh bourbon. It is perfectly clear until aged in specially made white-oak barrels which are seen above. There are numerous warehouses storing the barrels of liquor in various stages of aging.
