Pot stills at the Lagavulin Distillery. A pot still is a type of distillation apparatus or still used to distill liquors such as whisky or brandy.In modern (post-1850s) practice, they are not used to produce rectified spirit, because they do not separate congeners from ethanol as effectively as other distillation methods.
Distillation by column still is the traditional method for production of Armagnac, although distillation by pot still is allowed. The use of column stills for the distillation of Cognac is forbidden, although they may be used for other types of brandy , likewise malt Scotch Whiskies must be distilled in a pot still.
The simplest standard distillation apparatus is commonly known as a pot still, consisting of a single heated chamber and a vessel to collect purified alcohol. A pot still incorporates only one condensation, whereas other types of distillation equipment have multiple stages which result in higher purification of the more volatile component ...
This was how Coffey became familiar with a design differing from the traditional copper pot alembic still commonly used in Ireland, the continuous, or column, still. First patented by a Cork County distillery in 1822, the column still remained a relatively inefficient piece of equipment, although it pointed the way towards a cheaper and more ...
Before the 19th century most distillation was performed from a simple pot still developed in 800 AD by the Arab alchemist Jabir ibn Hayyan. In the early 19th century the advent of steam heating and later the continuous "patent" still radically transformed the spirits industry. Smaller traditional producers developed marketing strategies to ...
A sketch of Shee's Patent Still The distillery was home to an early continuous distillation apparatus, was which installed and used at the distillery for almost twenty years. [ 1 ] The apparatus, which the distiller's co-owner, Joseph Shee, patented in 1834, was similar to Jean‐Édouard Adam's 1801 design , and consisted of a four pot stills ...
A pot still is a type of distillation apparatus or still used to distill flavored liquors such as whisky or cognac, but not rectified spirit because they are poor at separating congeners. Pot stills operate on a batch distillation basis (as opposed to a Coffey or column stills, which operate on a continuous basis).
Diagram of a Batch Rectifier. The simplest and most frequently used batch distillation configuration is the batch rectifier, including the alembic and pot still.The batch rectifier consists of a pot (or reboiler), rectifying column, a condenser, some means of splitting off a portion of the condensed vapour (distillate) as reflux, and one or more receivers.
