                                Based on standard nutritional data, a single 1.5-ounce shot of 90 proof bourbon contains approximately 110 calories. The exact amount depends on the alcohol content, as the distillation process removes carbohydrates and fats, leaving behind only the caloric content of the alcohol itself.
