Sidestills

A sidestill is a type of still used in the production of distilled spirits, particularly in the production of rum and whiskey. Unlike pot stills, which are cylindrical and have a single heating element, sidestills are rectangular and have multiple heating elements, or "fires," running along their length. This design allows for more efficient heating and distillation, as the liquid flows through the still in a continuous process rather than being heated and then distilled in batches.

Sidestills are typically made of copper or stainless steel and are designed to be easily disassembled for cleaning and maintenance. They are often used in small-scale or artisanal distilleries, as they can produce a higher-quality spirit with a more complex flavor profile. However, they are also used in larger-scale operations, such as in the production of commercial rum.

The process of distillation in a sidestill involves heating the liquid, which causes the volatile compounds to evaporate and rise to the top of the still. These compounds are then condensed and collected as the distilled spirit. The remaining liquid, known as the "bottoms," is typically discarded or used in other processes.

Sidestills are named for their rectangular shape, which allows for the liquid to flow along the length of the still, rather than being heated and then distilled in a single chamber. This design allows for more efficient use of heat and can result in a higher-quality spirit.
