Whisky words: Coffey Still / Continuous Still
Aeneas Coffey (1780–1839) was an Irish inventor and distiller who patented the continuous still. It is also known as a column still, patent still or Coffey still.
It consists of two columns, a rectifier and analyser. It is used to produce grain spirit and typically comes off the still at a much higher Alcohol by Volume (ABV) than malt new make spirit. It can work 24 hours a day and produce spirit on a much larger scale than a pot still.
