Corn whiskey is a type of alcoholic beverage made primarily from corn and other grains that are brewed into a mash, then fermented and distilled to remove the alcohol. Among the oldest and most famous whiskeys produced in the United States is Jack Daniels. Jack Daniels whiskey has little value as a food source, providing no important nutrients. It does contain significant quantities of ethyl alcohol, which does have some caloric value.
Jack Daniels is classified as "straight corn whiskey" by the Federal Standards of Identity for Distilled Spirits. The standard states that corn whiskey made in the United States must be made of grain with no less than 80 percent corn. Corn whiskey is required to be aged in charred oak barrels at no greater than 160 proof by volume for at least two years and can only be sold at 80 proof. Jack Daniels is pure 80 proof corn whiskey.
One fluid oz. of Jack Daniels whiskey weighs around 42 g, the United States Department of Agriculture Nutrient Database says. That serving provides around 15 g of alcohol. There are no carbohydrates, proteins or fats in Jack Daniels. The remainder of this serving consists of 27 g of water.
There are around 65 calories within a 1-oz. serving of Jack Daniels whiskey. They call come strictly from the alcohol. No calories are obtained from carbohydrates, protein or fat. A single oz. of Jack Daniels can provide around 5 percent of the caloric intake per day for the typical adult, based on a 2,000-calorie diet.
The USDA Nutrient Database indicates there are no appreciable quantities of either vitamins or minerals in Jack Daniels whiskey. Also, there is no dietary fiber.
While the alcohol in Jack Daniels whiskey has some nutritional value from the calories it provides, it is also a strong drug. When ingested in sufficient amounts, alcohol affects the central nervous system, altering perception, impairing judgment and impulse control, coordination, vision and reflexes. Excessive quantities of alcohol can even induce coma or result in death.
