What spirit can be distilled from corn, potatoes, wheat, and/or rice?

The correct answer is vodka, as it is a versatile spirit that can be distilled from a wide variety of fermentable materials, including corn, potatoes, wheat, and rice. This flexibility allows vodka producers to create different flavor profiles and characteristics depending on the base ingredient used.

For instance, corn can produce a sweeter and fuller-bodied vodka, while potatoes may impart a creamier texture, and wheat often leads to a smoother finish. Rice, too, is utilized particularly in Asian countries, resulting in a lighter style of vodka that can have delicate flavors.

On the other hand, rum is predominantly made from sugarcane or molasses, which eliminates it as a contender for this question. Whiskey is specifically distilled from grains like barley, rye, corn, and wheat but is not made from potatoes or rice, which restricts its scope. Tequila, meanwhile, is made exclusively from the blue agave plant and does not fit into the category of grains or starchy vegetables. Thus, vodka stands out as the only spirit here that can be distilled from all the specified ingredients.
