Bottle for secondary fermentation
Champagne’s traditional-method bottle holds wine through its second fermentation and subsequent maturation on lees. At tirage it has a crown cap and internal insert; bottle formats and specifications vary.

Column still
A column still is a distillation apparatus built around one or more vertical columns. Its continuous and rectifying designs appear in several spirits traditions, but materials and product character vary by installation.
A column is a design family, not a single machine
A column still is distillation equipment arranged around one or more upright columns. A 19th-century account of Aeneas Coffey's design distinguishes an analyzer from a rectifier; it describes vapour and liquid passing through plated sections as part of a continuous apparatus. The Science History Institute preserves a contemporary 1877 illustration of Coffey's patented still. These records document a specific industrial design lineage rather than the origin of every apparatus now called a column still.
The name covers varied plant. A photograph from Destilleriet Als in Denmark shows a 350-litre example with a substantial vessel and tall metal columns; Rhum J.M describes two traditional Creole copper columns. Neither example supplies a universal blueprint, size or material specification. Columns may be copper, stainless steel or combined with other equipment, depending on the installation.
Continuous operation and rectification
Column equipment can support continuous distillation, unlike the familiar image of a pot still charged and emptied in separate batches. Coffey's 1830 patent is an attested milestone in commercially viable continuous distilling, not proof that every column plant follows an identical operating pattern. A column's internal plates or other contact arrangements permit repeated interaction between rising vapour and descending liquid; the historical sources explain this in relation to analyzer and rectifier designs, while a maker's production page is the best evidence for how a particular plant is run.
These distinctions matter because the apparatus alone does not tell a reader what the resulting spirit will taste like or how it is made. Angostura describes continuous columns in its rum production. Takamaka's Seychelles Rum Blanc is a product-specific blend: the producer says its molasses-based column rum is distilled up to 94% ABV and combined with a touch of high-ester pot-still rum. That claim belongs to this rum, not to all column distillation.

One apparatus, different spirit traditions
Producer documentation places column stills in several distinct settings. Rhum J.M describes two copper columns at its Martinique estate. Rockland's Ceylon Arrack account follows coconut flower sap as it ferments naturally into toddy and states that the fermented liquid is distilled in columns. In Georgia, Askaneli identifies a column still for its Chacha Platinum, a named grape spirit; the entry does not imply that every chacha producer uses the same plant.
Absolut describes continuous distillation for its vodka made in Åhus, Sweden. Angostura describes its own Trinidad and Tobago rum columns. The examples show the equipment's range, but they do not establish a single geographic birthplace or a universal recipe. The linked chacha, coconut arrack and white rum pages point to documented product contexts; they should be read as specific applications rather than evidence that every preparation uses the same model.

Materials, scale and what remains unknown
Copper is documented for Rhum J.M's columns and for the later double-column Coffey designs described in the historical account. Modern distillery photographs also show metal assemblies in which copper and stainless components appear together. That does not make either material mandatory across the category. The inspected sources give no general capacity, height, diameter, maintenance schedule or consumer acquisition route. The Danish photograph's 350-litre caption refers to that photographed example only.
Column stills are normally described as fixed distillery equipment rather than a kitchen vessel, and their manufacturers and operators specify their construction and care. The source set does not document one general cleaning routine or safety protocol, so this page does not prescribe one. The best way to understand any specific still is through its maker's technical documentation and the distillery's own account, while keeping the historical Coffey design distinct from modern installations.

History
An 1877 Philadelphia encyclopaedia preserves a diagram of Coffey's patented still; a historical account dates Coffey's patent to 1830 and describes the evolution of analyzer and rectifier columns. This marks an attested industrial design, not the invention of every column still.
Equipment details
CapacityNo class-wide capacity is established by the inspected sources. The Commons photograph captions one particular Destilleriet Als example at 350 litres; it is not a standard size.
SizeNo general dimensions are established; stills vary by producer and installation.
PowerNot established The category includes installations with differing heat, steam and utility arrangements; the inspected sources do not establish one general power source.
How you get oneBought, manufactured The producer sources describe industrial distillery equipment, but do not establish a standard retail model, price or route for readers to acquire one.
CareThe inspected sources do not establish a general cleaning, inspection or maintenance schedule for column stills. Industrial designs and operating requirements vary; care instructions must come from the manufacturer and site operator.
Made of
- Copper — documented column and plate material
Rhum J.M describes copper columns; the Coffey history source describes copper columns and plates in a later double-column design. Not all columns are copper. - Stainless steel and copper — materials visible in one modern example
Visible in Yukonmanner's photograph of Destilleriet Als; not a specification for the whole category.
Limits
A column still does not guarantee a neutral or uniform spirit: producers document distinct products and, in Takamaka Rum Blanc, a pot-still component alongside column-still rum.
