How many calories are in one shot of rum?

A 1-ounce shot of 80-proof rum contains roughly 64 calories according to the U.S. Department of Agriculture. But Drinks Mixer's listings show that rums can vary in caloric density. For example, Myer's Dark Rum and Bacardi's Spiced Rum both contain 69 calories per ounce.

Alcohol distillers are not required to label their products with nutrition facts in the same way food manufacturers do, though the federal government has created a voluntary labeling program for beer, wine and liquor companies. In some cases, rum manufacturers may list the calorie contents of their products online; if they don't, it's generally safe to estimate that 1 ounce of rum contains 60 to 70 calories.
