A single pot still is a type of distillation apparatus used primarily in the production of Irish whiskey. It combines both malted and unmalted barley, which contributes to its unique flavor profile. The process involves heating the mash in a pot still, allowing the alcohol to evaporate and then condense back into liquid form. This method is distinct from other distillation techniques, such as column stills, which typically use only malted barley. The single pot still process results in a rich, full-bodied spirit, often characterized by a creamy texture and complex flavors, making it a favorite among whiskey enthusiasts.
