> Most whiskey fans know the difference between a pot still and column still. The first consists of a big heated pot beneath a tapering neck to guide vapors up and over to a cooled condenser on the other side. The second is a tall, cylindrical column fitted with some number of plates to give the vapor more reflux on its path from mash to spirit. In Scotland, pot stills are used to make malt whisky, and column stills make grain whisky.
