Continuous still
Refers to the column
still design patented by Aeneas Coffey in 1830. A more efficient alternative to the
pot still, it is capable of continuous
distillation by reheating the liquid, rather than requiring distillation in batches, and can produce higher ABV spirits than pot stills. The device consists of two columns which contain a number of compartments separated by heated plates. The plates are perforated with small holes to permit the upward passage of steam and spirit vapor, which is condensed to become spirits. Often referred to as a
Coffey still or
column still. For more information, see "
