To what percentage abv must vodka be distilled?

Vodka must be distilled to a high purity level, typically between 95-96% alcohol by volume (abv). This high distillation percentage is essential for producing vodka's neutral flavor and smooth texture, which are characteristic of this spirit. The distillation process involves removing impurities and congeners that can affect the taste and clarity of the final product.

Distilling vodka to this level also allows for the possibility of dilution with water before bottling, achieving the desired drinking strength, which is commonly around 40% abv. This practice is in line with traditional vodka production methods, particularly in countries such as Russia and Poland, where vodka originates. A lower distillation percentage, as seen in the other options listed, would result in a spirit that carries more flavors and characteristics from the raw materials used, deviating from the clean profile that vodka represents.
