A standard 1.5-ounce (44 ml) shot of tequila contains approximately 90 to 97 calories, depending on the alcohol content and brand. For example, Altos tequila has about 91 calories for the 38% alcohol version and 95 calories for the 40% version per shot

. Other sources report similar values, around 96 to 97 calories per 1.5-ounce serving

. In terms of calories per ounce, tequila has roughly 65 to 69 calories per fluid ounce, with no fat, carbohydrates, or sugar, as it is a distilled spirit made from agave

. Different types of tequila-Blanco, Reposado, Añejo-have very similar calorie counts per volume, generally around 207 to 218 kcal per 100 ml (about 3.4 ounces)

. In summary:

• 1.5 oz (44 ml) shot of tequila: ~90–97 calories
• 1 oz (28 ml): ~65–69 calories
• No fat, carbs, or sugar in pure tequila
• Calorie count varies slightly with alcohol percentage but not significantly between tequila types

Cocktails made with tequila, like Margaritas or Palomas, have higher calories due to added mixers and syrups
