In 1891 a whisky expert noted that Craigellachie represented a whisky 'seldom met with now' which the distillery took as a compliment. Today they still use old - fashioned 'worm tubs' to cool their spirit and bestow it with extra flavour creating a dram to rival whiskies twice its age. A worm tub is a long copper tube, sitting in a large tank of cold water, which shakes back and forth and gradually gets narrower. In 1891 many distilleries condensed their spirit this way, giving their whiskies a distinctive meaty character. Craigellachie is one of very few still benefiting from this traditional technique.
