distilled spirit The fermentation and distillation process for producing whiskey. The production of whiskey begins with grinding grain into a meal, which is cooked. Malt is introduced to the meal, which results in mash that is cooled and pumped into a fermenter, where yeast is added. The fermented mixture is heated in a still, where the heat vaporizes the alcohol. The alcohol vapours are caught, cooled, condensed, and drawn off as clean, new whiskey. This liquid is stored in a cistern room, and water is added to lower the proof (absolute alcohol content) before the whiskey is placed in new charred oak barrels for aging and later bottling.

The Industrial Revolution significantly transformed the production of distilled spirits by enabling advancements in technology and scale.

Prior to this era, the high steam requirements for operating continuous stills hindered the development of rectifying columns. Following the Industrial Revolution, these technological barriers were overcome, allowing for the widespread adoption of large-scale continuous stills. A notable innovation occurred in 1831, when Aeneas Coffey designed a continuous still consisting of two columns in series, a design that remains foundational to the modern industry.1

Additionally, the growth of the distillery business during the 19th century led to the large-scale production of spent grains, or "swill," as a byproduct. In the United States, this waste material was frequently used to feed dairy cows, a practice that became a significant public health concern due to the poor nutritional quality of the resulting milk. Overall, the era shifted distillation from smaller operations toward more efficient, high-volume industrial processes.21
