Whisky distillery. Engraving of distillation apparatus used in 1690 to make whisky. Whisky is made by concentrating the alcohol content of beer by heating it in a still (at left). 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,which is a barrel of water here (at centre right). The vapour in the pipe cools,condenses back into a liquid and runs out of the pipe for collection in a pot (at right). This fluid is then placed in barrels for a certain length of time to mature,giving the whisky its own,distinctive flavour | |
