Pot still bourbons are increasingly common in the craft whiskey world, but how do they differ from so many classic Kentucky bourbon whiskeys?

It actually has two columns, called the analyzer and the rectifier, and it is, as Max describes, extremely efficient at separating alcohol from filtered wash, the distiller’s beer.

Beluga Vodka is made from a mash bill of 100% Scandinavian organic wheat. The wash undergoes a meticulous fermentation and distillation process utilizing a column still with six rectification columns.

At various points in the distillation process, the Arduino plays audio files of a robot voice saying what’s going on in the still. Right now, [Tegwyn] is distilling barley wine and cider into ...

That happens in distillation, during which the liquids are further purified and concentrated with greater alcohol content through repeated boiling and condensation.

Comparatively, the pot stills at Specific Mechanical Systems can achieve a maximum distillation of 60-80% ABV (alcohol by volume), whereas their new continuous columns can reach 96%.

Specifically it's a reflux still that uses vacuum distillation, which doesn't look as cool as a pot or column still, but makes far more efficient use of the space.

A column still is static, the mash (the mix of fermented base ingredients) is continuously fed into the top of the contraption, and the alcohol is continuously harvested from the bottom. Nonstop.
