The number of calories in a shot, or 1.5 ounces, of 80-proof whiskey is 98. In a 1.5-ounce glass of 86-proof whiskey, the caloric count rises to 106, with 111 calories in the same size glass of 90-proof whiskey. A 1.5-ounce glass of 94-proof whiskey contains 116 calories, while 100-proof whiskey in the same size glass contains 123 calories.
The calorie counts for 1.5 ounces of whiskey also apply to other distilled spirits, such as vodka and gin.
The Jim Beam Whiskey distillery was established in 1795 by Jacob Beam, who perfected the ingredients in the drink in 1795. A farmer and grain mill operator, Beam arrived from Germany in 1778, landing on Kentucky soil and towing the parts to build a copper still. The future whiskey maker established his bourbon-making operation close to Dardin Creek, Kentucky.
The bourbon makers from Jim Beam say that bourbon can be whiskey but whiskey is not necessarily bourbon. For example, Tennessee whiskey and Scotch are bourbon whiskeys. Jim Beam notes that bourbon is sweeter than whiskey and must be produced, by law, with at least 51 percent corn in a mix of wheat, barley and rye. The spirit must be less than 160 proof and contain no additives. Only water is used to lessen the proof. The mix must be aged for two years in unused white oak charred barrels.
