The terms "spirit" and "alcohol" are often used interchangeably, but they refer to different aspects of alcoholic beverages. "Alcohol" is a chemical compound known as ethanol, which is the primary psychoactive ingredient in alcoholic drinks. On the other hand, "spirits" refers to specific types of alcoholic beverages produced through distillation, containing higher concentrations of alcohol compared to beer and wine.

Spirits contain calories primarily derived from alcohol, with little to no nutritional value. They are typically low in carbohydrates, fats, and proteins. A standard serving of spirits, such as a shot or 1.5 ounces, contains around 97 calories. However, the calorie content can vary depending on the specific type of spirit and any additional ingredients used in cocktails or mixers.

Any spirit can be used to make a cocktail. Cocktails are simply mixed drinks made with distilled liquor. Examples include margaritas, martinis, and mai tais.
