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 ...
English: Prohibition-era copper still pot, column, and condenser (c. 1920). From the collection of the McCleary Historical Museum, McCleary, Washington.

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]
Pot stills made of various materials (wood, clay, stainless steel) are also used by bootleggers in various countries. Small pot stills are also sold for use in the domestic production [35] of flower water or essential oils. Early forms of distillation involved batch processes using one vaporization and one condensation. Purity was improved by ...
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)
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 ...
A Dimroth condenser, also known as a spiral condenser, named after Otto Dimroth, is somewhat similar to the coil condenser; it has an internal double spiral through which coolant flows such that the coolant inlet and outlet are both at the top. [19] [20] The vapors travel through the jacket from bottom to top. Dimroth condensers are more ...
