By the early 19th century, the introduction of increasingly restrictive manufacturing regulations, access to resources, and the engineering of sequential compartments for distillation reshaped the distilling industry, as steam boilers permitted continuous closed systems that revolutionised production efficiencies, leading to higher volumes.
