Coffey Still
Named for its designer, engineer Aeneas Coffey, the Coffey or columnar still was originally introduced in Dublin, Ireland in 1830 and patented in Dublin in 1831. This design is, with little improvement, still widely used today.
The Coffey still continuously produces a lighter spirit than a traditional pot still and the resulting distillate is usually aged in previously-used barrels to impart additional character.
