What type of still is typically used for the distillation of vodka?

The distillation of vodka typically employs a column still, also known as a continuous still or patent still. This type of still is designed for efficient, continuous processing, which allows for a higher level of purity and higher alcohol concentration. The design of a column still involves multiple plates or trays, which enables the vapor to pass through the liquid and undergo repeated distillation as it rises through the column. This process results in a clean, neutral spirit that is characteristic of vodka.

In contrast, a pot still is generally used for making spirits that are more flavor-intensive, such as whiskey or rum, because it generally provides a lower level of purification and allows for the retention of more complex flavors. Batch still and continuous still can refer to varying methodologies, but specifically, continuous still is the best terminology for those used in vodka production due to its capacity for volume and efficiency. Thus, the column still's attributes make it the predominant choice for vodka distillation.
