Is vodka always 40%?

As an expert sommelier and brewer, I can tell you that while the standard proof of vodka is indeed 80, which translates to 40% alcohol by volume (ABV), it is not always the case that vodka is exclusively 40% ABV. The proof or alcohol content of vodka can vary depending on the country of origin and the brand.

In the United States, the Alcohol and Tobacco Tax and Trade Bureau (TTB) requires that all vodka be at least 80 proof, or 40% ABV. This standard is set to ensure consistency and quality across different vodka brands available in the market. However, it is important to note that this requirement is specific to the U.S. and may not apply universally.

Internationally, the standard for vodka can vary from country to country. While 40% ABV is still common in many parts of the world, there are countries where vodka with higher alcohol content is legally sold. For example, in Poland, where vodka holds a significant cultural importance, the traditional vodka known as “spirytus” can have an astonishingly high proof of 192, or 96% ABV. This extremely potent vodka is not meant to be consumed straight but is often used as a base for homemade liqueurs or in small quantities for medicinal purposes.

Furthermore, within each country, different brands may offer vodka with varying alcohol content. Some brands may produce vodkas with higher proof for those who prefer a stronger kick, while others may offer lower-proof options for those who prefer a milder taste. It ultimately comes down to the brand's production process, target market, and consumer preferences.

Personally, I have had the opportunity to taste and experience vodkas with different alcohol contents. I have encountered vodkas ranging from 35% ABV to as high as 55% ABV. Each had its own distinct characteristics and flavor profiles, with the higher alcohol content vodkas often exhibiting a stronger and more intense taste.
