The search for higher output

摘要

In Scotland during the 1820s, malt whisky was produced in direct-fired pot stills, typically with a capacity of about 2,250 litres. Grain whisky, produced from a mixture of malt and unmalted cereal, was distilled in the Lowlands and sold as a cheaper product and also exported to England for further rectification. The Lowland distillers also used pot stills though these were of greater capacity than those of the malt distillers. Dissatisfaction in the Lowlands with this slow, batch and labour-intensive process led to the quest for improved methods of distillation and between 1826 and 1832 different types of continuous still were investigated. The aim was to increase a distillery's daily output.
