How Is Vodka Made?

Vodka is fermented from a sugar or starch source, then distilled — usually multiple times, often in a column still — and filtered to maximise purity and neutrality.

Vodka's whole production philosophy is built around purity rather than showcasing raw-ingredient character, which shapes every step of the process.

1. Choose a base

Grain (wheat, rye, corn) and potatoes are the most traditional bases, though grapes, sugar beet, whey and other fermentable sources are also used — see "What is vodka made from?" for more detail. Because vodka is distilled and filtered so thoroughly, the base matters less to the final flavour than it does for a spirit like whisky or rum.

2. Fermentation

The base ingredient is mashed (if starch-based, this includes converting starch to sugar) and fermented with yeast to produce a low-alcohol wash, similar to the early stages of whisky or rum production.

3. Distillation

Vodka is typically distilled multiple times, and very commonly through column stills, which are especially effective at producing a highly rectified, close-to-pure ethanol output compared to pot stills. Some producers distil three, five, or even more times, marketing this as a mark of purity and smoothness.

4. Filtration

After distillation, many vodkas are filtered again — commonly through activated charcoal, though some brands use other media (like quartz sand or even diamond dust, marketed more for novelty than any dramatically provable flavour effect) — to remove any remaining trace compounds and further smooth the spirit.

5. Dilution and bottling

The highly rectified spirit is diluted with water down to bottling strength (commonly 37.5–40% ABV, sometimes higher) and bottled — vodka is not aged in wood.

See "Does expensive vodka taste better?" for how much all this extra processing actually shows up in a blind taste test.
