Copper pot stills are the most widely used method of distilling whisky. Copper is a great material for distillation as it helps to remove sulphur compounds and other impurities during the distillation process. This helps to create a clean, smooth, and flavourful whisky.
Copper also helps to enhance the flavour of the spirit as it reacts with the alcohol and creates esters, which are compounds that add flavour and aroma. Copper pot stills also help to preserve the original character of the whisky, as the copper helps to hold onto the more delicate aromas and flavours of the malt.
Overall, copper pot stills are an essential part of the whisky-making process and help to create a product that is smooth, flavourful, and unique.
