Description
Whisky distillery. Engraving of distillation apparatus used in 1729 to make whisky. Whisky is made by concentrating the alcohol content of beer by heating it in a still (labelled A"). Alcohol is more volatile than water, so there is a greater concentration of it in the vapour than there is in the remaining fluid. The vapour passes out of the top of the still in a pipe and into a condenser, ("B") which is a barrel of water. The vapour in the spiralled pipe cools, condenses back into a liquid and runs out of the pipe for collection in a pot. This fluid is then placed in barrels for a certain length of time to mature, giving the whisky its own, distinctive flavour."
