What is the required distillation proof for vodka in the US?

For vodka produced in the United States, the required distillation proof is 190 proof. This means that vodka must be distilled to an alcohol content of no less than 95% by volume. Distilling to this level ensures that the spirit is highly purified, allowing for the characteristic neutral flavor profile associated with vodka.

The high proof also plays a significant role in achieving the clean and smooth finish that vodka drinkers expect. It's important to note that different regulations exist for other spirits, but for vodka, the U.S. standards are specifically set at this distillation level to maintain quality and consistency within the category.
