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.
Pot still distillation gives an incomplete separation, but this can be desirable for the flavor of some distilled beverages. If a purer distillate is desired, a reflux still is the most common solution. Reflux stills incorporate a fractionating column, commonly created by filling copper vessels with glass beads to maximize available surface ...
This still had a pot still type-kettle, but replaced the traditional lyne arm and cooling worm with a vertical column of perforated plates. [7] Although many of the details of Cellier-Blumenthal's column were improved upon in later years, the general concept was to provide the basis for future column still designs. [5]

Between his Dublin education and his work as an excise officer, Aeneas Coffey had ample opportunity to observe the design and workings of whiskey stills; Ireland was the world's leading producer of whiskey in the 19th century, and Dublin was at the centre of that global industry. Coffey observed a design alternative to the traditional copper ...
the "cucurbit" (Arabic: ḳarʿa; Greek: βῖκος, bîkos), the still pot containing the liquid to be distilled, which is heated by a flame; the "head" or "cap" (إِنْبِيق, ʾinbīq; Greek ἄμβιξ, ambix) which fits over the mouth of the cucurbit to receive the vapors, with an attached downward-sloping "tube" (σωλήν, sōlēn)
It is used in combination with a reflux condenser and a distillation flask for the separation of water from liquids. This may be a continuous removal of the water that is produced during a chemical reaction performed at reflux temperature, such as in esterification reactions. The original setup by Julius Marcusson (invented in 1905) was refined ...
