The Physics of Double Retort Pot Stills and Thumpers

Pot stills are the oldest form of distillation and continue to be used across the world, but one of their main limitations is that the maximum ABV that can be attained in a single distillation is ~45% from standard 8-10% ABV wash. The small amount of high proof spirit from the first distillation will also be highly contaminated with low boiling compounds that range from unpleasant to unsafe, so it has traditionally required at least two pot still distillations to produce flavorful, drinkable spirit.

But double distillation is slow and expensive. Each run requires charging the still, consuming lots of fuel to heat it up, and cleaning out the remains in the pot after a run is complete. It also requires complex logistics to balance the flow of raw material through mashing, fermentation, and distillation so that equipment is being efficiently utilized. Distilling has always been a volume-driven business, so the more time it took to produce marketable spirit the less money a distiller was making on the vast amount of capital they had sunk into their plant, inputs, and labor. Somewhere in the 17th or 18th century distillers had the clever idea of hooking multiple pot stills together to perform multiple distillations simultaneously in series.

These types of stills are now uncommon, but can still be found in a number of rum distilleries across the Caribbean such as the double retort systems in Guyana , Appleton, Hampden, and Worthy Park in Jamaica, and Foursquare and Mount Gay on Barbados. They can also be found in many bourbon distilleries coupled to column stills under the title of 'doubler' or 'thumper'. All perform a secondary or tertiary distillation to boost the ABV of the output without having to manually perform a second or third distillation.

about the physics of pot stills and that background will be important for understanding what happens when they 

One of the most important parts of this process is what goes into the retort. If you put pure water in the retort the ABV of the output will not be significantly boosted, but some of the more water-soluble compounds may be scrubbed out, kind of like a hookah or bong. At many distilleries that use these systems, the retorts are loaded with what are called 'low wines' and 'high wines', which are respectively the tails and heads from previous distillations diluted to differing degrees depending on the desired output. Others, such as DDL, combine the heads and tails together before loading them into the retort. This replicates the practice in many distilleries with simple pot stills of recycling feints back into the wash still for redistillation. A visual description of that process can be found here. For more flavorful spirits, stillage or dunder (what remains in the pot after a previous run) can also be charged into the retorts to boost the ester content in the Cousin's process (this is a sufficiently complex topic that it will get its own post at a later date).

To cite one example of how a retort pot still operates, this report claims that Appleton's double retort pot still starts with 8% ABV wash that is converted into roughly 30% ABV output, which goes through the first retort charged with 30% ABV low wines and is converted into roughly 60% ABV output, which goes through the second retort charged with 75% ABV high wines to give a final product at 80-90% ABV.
