What is a primary ingredient in traditional vodka production?

In traditional vodka production, a primary ingredient can be potatoes. Although vodka can be made from a variety of sources, including grains like barley, rye, and wheat, potatoes are particularly notable because they were one of the earliest ingredients used in vodka production, especially in Eastern European countries. The fermentation and distillation process transforms the starches found in the potatoes into alcohol, resulting in a clean and neutral spirit that is characteristic of vodka. This versatility in ingredients is why vodka is often associated with several base materials, but potatoes hold a significant place in its history and traditional production methods.
