Everclear is a brand of vodka known for its high alcohol content. Most vodka brands are 40 to 60 percent alcohol, which is 80 to 120 proof. Everclear offers two varieties: Everclear 190 proof, which has 95 percent alcohol content, and Everclear 151 proof, which has 75.5 percent alcohol content.
Everclear is available in a variety of sizes for both the 151 and the 190 products. The bottles come in 375 milliliters, 750 milliliters, 1 liter and 1.75 liters. One serving size is equal to 1 ounce. However, keep in mind that for a standard mixed drink -- served at a bar, for example -- one shot equals 1.5 ounces.
One serving of Everclear has 190 calories. The 1-ounce serving contains 27 grams of alcohol, but no fat, carbohydrates, protein or sugars. Keep in mind that alcohol can have a slowing impact on your metabolism, and contains more calories per-gram than carbs, protein and fat. Mixing Everclear with juice or other beverages increases the caloric and nutritional content of the drink.
The USDA's Nutrient Database lists the nutrition information for a generic serving of 80-proof vodka. A 1-ounce serving contains 64 calories from 9 grams of alcohol, but no carbohydrates, protein or fat.
