Vodka & Grapefruit Calories

Mix vodka with grapefruit juice, pour it into an ice-filled highball glass, and you’ve got the cocktail known as a greyhound. This tasty cocktail may be a bit healthier than others thanks to the grapefruit juice, but it’s not calorie-free.


The vodka in your greyhound will contribute 65 calories per ounce. A typical greyhound has 1.5 to 1.75 oz, bringing the calories from alcohol to 98 to 114.


One 8 oz. cup grapefruit juice has 115 calories. Typically you’d mix 5 oz. into your drink, which equals 72 calories. That brings the total calories in your greyhound to 170 to 186, depending on whether you put 1.5 or 1.75 oz. of vodka in it.


Make your drink a double, meaning you double the amount of alcohol but not juice, and you add another 98 to 114 calories per drink. That adds up to 268 calories if you are pouring 1.5-oz shots. It adds up to 300 calories if you are pouring 1.75-oz shots.
