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.
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 ...
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.
In Ireland, where regulations define "pot still whiskey" as one distilled from a specific mixed mash of at least 30% malted barley, at least 30% unmalted barley, and other unmalted cereals in a pot still, "grain whisky" refers to whisky produced from a mixed mash of no more than 30% malted barley in a column still.

Single pot still whiskey is a style of Irish whiskey made by a single distillery from a mixed mash of malted and unmalted barley distilled in a pot still. [1] Somewhat similar to single malt whiskey, the style is defined by its inclusion of unmalted raw barley in the mash in addition to malt.
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).

Armagnac is traditionally distilled once, resulting in alcohol content between 52% and 60%.
