With out distillation, liquor couldn’t exist. Distillation is the tactic by which the alcohol present in a fermented liquid is separated after which concentrated. It’s achieved by heating the liquid after which cooling the vapors, condensing them proper right into a extraordinarily alcoholic spirit. This all works on account of ethanol evaporates at a lower temperature than water.
The gadget used on this course of is named a nonetheless. Over the centuries, stills have developed from rudimentary fire-heated pots to towering, industrial gear. To make liquor proper this second, distilleries primarily use two varied sorts of stills: pot stills and column stills. These two methods of distillation operate based mostly totally on the an identical fundamental guidelines nonetheless produce spirits with noticeably completely completely different qualities.
Proper right here’s the whole thing you may find out about pot stills vs. column stills.
Column vs. Pot Nonetheless Fast Data
• Pot stills are huge pot-shaped stills which could be typically product of copper and distill spirits on a batch-by-batch basis.
• Column stills embody a minimal of 1 tall cylindrical column. They’re typically operated consistently and produce spirits further successfully.
• Normally speaking, pot stills create richer and additional flavorful spirits whereas column stills are most popular for further neutral spirits.

What Is a Pot Nonetheless?
The oldest and most straightforward methodology of distilling a spirit is batch distillation, further usually typically known as pot distillation. This trend of distilling makes use of a giant pot-shaped nonetheless to provide a spirit. Pot stills are sometimes product of copper and have a extremely giant base that tapers vertically into a thin neck.
These stills are full of a fermented alcoholic liquid that is derived from an agricultural product like grain, sugar cane, or fruit. This low-ABV liquid, typically known as the wash, is then heated. “Alcohol and completely different volatiles that boil at temperatures lower than water will probably be eradicated when heated to shut boiling,” explains Dr. Pat Heist, chief scientific officer and co-founder of Wilderness Path Distillery.
The vapors that emerge from the pot as a result of the liquid heats up are collected, then cooled and condensed proper right into a distillate correct off the pot. They are often further processed through a group of rectifying plates that finish in bigger proofs, and the distillate is usually distilled a second time to appreciate the desired focus of alcohol.
“It is the distiller’s administration of that heating and condensing course of that allows for the occasion of a desired style profile,” says Chris Morris, grasp distiller emeritus at Earlier Forester and Woodford Reserve.
Pot distillation isn’t most likely essentially the most setting pleasant choice to create alcohol, primarily on account of it operates on a batch-by-batch course of. “A pot nonetheless is stuffed, heated, emptied, after which stuffed as soon as extra,” says Morris. No matter their inefficiency, pot stills produce spirits which could be sometimes renowned for his or her rich flavors and aromas.

What Is a Column Nonetheless?
Column stills, typically often known as regular, patent, or Coffey stills, have been developed inside the early 1830s and are nonetheless extensively used proper this second. These stills are far more superior than pot stills. To put it very merely, column stills comprise a minimal of 1 tall cylindrical column. Contained in the column, vertically stacked plates separate the column into compartments. The nonetheless is heated from beneath by steam, inflicting the wash to evaporate and journey vertically through the nonetheless. Vapor begins to condense throughout the plates, stripping the water and completely different undesirable compounds in a course of typically known as reflux. The alcoholic vapor lastly reaches the best of the nonetheless and is then condensed proper right into a spirit.
In distinction to pot stills, column stills can run consistently with out the need to clear and refill the nonetheless. “This course of can run for days at a time, 24/7,” says Morris. Column stills are moreover able to distill liquor to a significantly bigger alcohol content material materials.
“We use column stills primarily for bigger throughput manufacturing, nonetheless we moreover obtain a serious amount of consistency on account of ‘cuts’—heads, hearts, and tails—being further automated compared with a pot nonetheless,” says Heist.
For all of these causes, column stills are terribly setting pleasant and since their invention, have been extensively adopted all through the entire world of distilling.
The Distinction Between Column and Pot Nonetheless Spirits
The variations between regular and pot distillation would possibly appear like technical trivia, nonetheless they’ve an enormous impact on the way in which during which the finished spirit tastes. Resulting from these variations, one form of distillation is usually most popular over the other by producers of a specific spirit. Broadly, though, any spirit will probably be made with each form of nonetheless.
To be clear, the distillation methodology is definitely certainly one of a plethora of variables that affect how a spirit tastes. “Style, aroma, and mouthfeel will depend on explicit individual recipes, nonetheless kind, distillation proof, and many completely different elements,” says Morris.
The gradual, batch distillation of pot stills supplies the spirits they produce a extremely rich and distinctive character. “Normally speaking, pot stills often create darker liquids with intense aromas,” says Heist. Pot stills are most continuously used to provide full-flavored spirits like tequila, some Jamaican rums, mezcal, and many malt whiskeys. Quite a lot of subcategories, like single malt Scotch whisky and cognac, are legally required to be made on pot stills.
Column stills produce liquids which could be milder in style and have a smoother mouthfeel than distillate made with pot stills. They largely produce vodka, gin, and some varieties of rum, along with most bourbon whiskey. Resulting from their effectivity, they’re sometimes used to distill neutral-flavored spirits which may take a lot of distillations on a pot nonetheless to create. Neutral spirits are generally used as the underside of liqueurs, bitters, and completely different comparable merchandise.
Light, neutral spirits aren’t the one issue column stills can produce. “These are all generalizations,” says Heist. “It is extensively acknowledged that column stills can create superior and full-bodied spirits, significantly inside the case of ryes and bourbons.”
The distillation course of is a vital variable that significantly influences the traits of the finished product. Whereas every methods are rooted within the an identical fundamental guidelines of distillation, the technical variations between pot and column distillation yield spirits with distinct qualities. Although it isn’t a really perfect predictor, determining how a spirit was distilled can current vital notion into how a liquor will model.
