Still house exterior showing the square worm tubs. The water in the worm tubs is kept hot, which keeps the spirit as a vapour for longer, prolonging reactivity with the copper. This helps Royal Lochnagar achieve a light spirit even though the stills are quite short (which would normally produce a heavy spirit).
