A column still strips congeners aggressively through repeated reflux on perforated plates inside a vertical column, producing a high-ABV, low-character spirit that fits the modern definition of vodka. A pot still works in single batches, retains more of the original grain character because of its lower reflux, and produces a more flavorful but less neutral spirit. Most contemporary vodka comes off a column still. A growing number of craft producers run a hybrid setup that uses both.
How a Column Still Works
A column still is a vertical tower divided into a stack of perforated plates, also called trays. Wash enters near the bottom, heat is applied, and ethanol vapor rises through the plates. As the vapor moves up, it repeatedly condenses on the cooler plate above, drips back down, re-evaporates, and keeps climbing. Each plate acts as a miniature distillation cycle. A column with twenty plates is essentially running twenty distillations in series.
The result is a spirit that comes off the top of the column at a very high ABV, often 90 to 95 percent, with most of the original congeners stripped out at the various plate stages. That high-purity stream is exactly what the vodka category was built around. A continuous column still also runs without stopping. Wash goes in continuously at the bottom, finished spirit comes out continuously at the top, and the still does not need to be drained between batches. That makes column stills the workhorse of large-scale vodka production.
How a Pot Still Works
A pot still is a copper or stainless vessel, more or less a kettle with a curved neck on top called the lyne arm. Wash goes in, heat is applied, vapor rises through the neck and into a condenser, and the resulting distillate is collected. When the run is done, the pot is drained and refilled for the next batch.
A pot still has only a single distillation pass per batch, which means most of the congeners and grain character carry through into the distillate. To get to vodka strength, a pot-still operator typically does at least two passes, sometimes three, with a careful cut between the heads, hearts, and tails on each pass. Even with multiple passes, a pot-distilled spirit retains more of its grain character than a column-distilled one. That is the whole point. Whisky, brandy, and most rum traditionally use pot stills for exactly that reason.

Which Vodkas Use Which Equipment
The vast majority of widely available vodka is column-distilled. That includes most of the bottles on a typical Pennsylvania Fine Wine and Good Spirits shelf, from the high-volume international brands down through the mid-tier and into the craft tier. Column distillation is the only practical way to hit the neutrality the vodka category demands at scale.
Pot-still vodka does exist, mostly in the craft segment, and it tends to be a more textured, grain-forward bottle that some drinkers love and others find too rough for a martini. A growing number of small distilleries run a hybrid setup that uses a pot still for the first pass to capture some grain character, then a small column for the finishing passes to bring the spirit up to the target ABV without sacrificing every trace of the source grain. Hybrid setups give the distiller more dials to turn.

The takeaway: at production scale, almost every vodka you can buy is column-distilled. Hybrid and pot-still vodka exists in the craft segment, but it remains the exception rather than the norm. If a vodka brand markets itself as "pot still distilled," check whether that refers to current production or a heritage marketing claim.
Common Still Manufacturers Distillers Trust
For readers who want to go a level deeper, the still itself is usually built by one of a small set of specialty manufacturers. Vendome Copper and Brass Works (Louisville, Kentucky) and Holstein (Germany) are the two most-named manufacturers among American craft distilleries. Kothe (Germany) builds the hybrid pot-and-column rigs that several American craft producers run. Bennett Forge (United States) and CARL (Germany) round out the most common short list. The manufacturer choice shapes the spirit at the margins, even before the distiller lights the burner.
Why Armen's Barrels Runs a Continuous Column for FLORENA
We use a continuous column still for FLORENA Diamond because the profile we are building is a clean, six-pass corn-based vodka that needs to read consistently from one bottle to the next. A pot-still build would give us more grain character but it would also give us more batch-to-batch variation, and consistency is part of what a USDA-certified bottling has to deliver. The column setup also lets us run efficiently without stopping for batch turnover, which matters for a distillery our size that bottles to spec for over 100 stores in the Pennsylvania system.
For our Butterfly Pea Gin, we still build the base on the column, then handle the botanical infusion separately. For our brandy line, the equipment story is different and pot-style methods are central. Different spirits, different equipment.
"Column versus pot is not a quality question. It is a what-are-you-trying-to-make question. If you want vodka neutrality, you build on a column. If you want grain character, you reach for a pot. Anyone telling you one is universally better is selling something." Phil Ejzak, Head Distiller, Armen's Barrels
FAQ
Is column-distilled vodka better than pot-distilled vodka?
Better is the wrong frame. They produce different spirits. Column distillation gives you cleaner neutrality, which is what the vodka category was built for. Pot distillation gives you grain character, which is great in whisky and divisive in vodka.
Why do most vodka producers use column stills?
Three reasons. The output ABV is high enough to skip extra distillation passes, the system runs continuously, and the resulting spirit hits the neutrality the category demands.
Can a single still do both?
A hybrid still has both a pot section and a small column section, often switchable. Some craft distilleries use a hybrid to make whiskey one week and vodka the next. The result is rarely as pure as a dedicated column setup, but the flexibility is the point.
Does pot-distilled vodka qualify legally as vodka?
Yes, as long as it meets the federal neutrality and ABV requirements at bottling. The pot-still operator just has to work harder to strip enough congeners, which usually means more passes and aggressive filtration.
Where can I taste a column-distilled organic vodka built for clean neutrality?
Pour FLORENA Diamond at room temperature in a tasting glass. The clean profile is the column-still effect. Available across the Pennsylvania Fine Wine and Good Spirits system and through the Armen's Barrels online store.
If you want to taste the difference equipment makes, set up a flight of one column-distilled vodka and one pot-distilled vodka at the same ABV, neat, room temperature. The textural and aromatic gap will be immediately obvious. Want to start with the column side? FLORENA Diamond is the cleanest expression of the method we make.
