Which of the following is a common source of vodka in the United States?

Corn is a common source of vodka in the United States primarily due to its abundant availability and the fact that it is one of the most widely grown crops in the country. Vodka can technically be produced from numerous sources of carbohydrate, but the use of corn is particularly prevalent as it not only provides a neutral flavor profile, which is characteristic of vodka but also offers a smooth and clean spirit when distilled properly.

In addition to being cost-effective, the fermentation process of corn results in a vodka that is often considered more approachable and palatable for a wide range of consumers. Many American vodka brands highlight corn as their base ingredient, reinforcing its popularity and significance in the vodka market.

While winter wheat, potatoes, and rye are also used in vodka production, they tend to be less common in the U.S. market compared to corn. Varieties made from these other ingredients often represent specific styles or regional preferences rather than the mainstream production associated with corn-based vodkas.
