The flatliner is not a single drink but a name applied to at least two distinct and popular cocktail recipes. This ambiguity means that asking "how many calories are in a flatliner" doesn't have a single answer. The calorie content depends entirely on the version you're referring to—the traditional, fiery tequila shot or the rich, creamy espresso-based martini. In this guide, we break down the ingredients and calories for both versions so you can make an informed choice.
The fiery flatliner shot: A spicy calorie count
The most commonly recognized flatliner is a layered shot, popular in bars for its potent combination of sweet, fiery, and agave flavors. This variant is typically made with sambuca, tequila, and hot sauce.
Ingredients and calorie breakdown
- Sambuca: Anise-flavored liqueur. A standard one-ounce serving contains around 113 calories.
- Tequila: An 80-proof tequila contains approximately 64 calories per fluid ounce.
- Hot Sauce: The amount used in a flatliner shot is typically a few dashes, contributing a negligible number of calories.
Based on a popular recipe calling for one ounce of sambuca and one ounce of tequila, the calorie count for this version is around 177 calories. However, recipes and pour sizes can vary greatly, leading to a wide range of estimates. For example, some sources cite a range from 110 to 224 calories, depending on the specific recipe and proportions. The total calorie count is directly tied to the total alcohol content, as alcohol provides seven calories per gram.
The creamy flatliner cocktail: A decadent calorie count
The second, more indulgent flatliner is a dessert-style martini made with vodka, coffee liqueur, Irish cream, and espresso. Often served in a chilled coupe or martini glass, this version is a creamy, caffeine-fueled treat.
Ingredients and calorie breakdown
- Vodka: A one-ounce serving of 80-proof vodka adds approximately 64 calories.
- Coffee Liqueur: Typically, a brand like Kahlúa is used. One ounce contains about 117 calories.
- Irish Cream: A creamy liqueur like Baileys. One ounce has around 93 to 107 calories.
- Espresso: A single shot adds a minimal 3 calories.
For a recipe using one ounce of each liquor and a shot of espresso, the calorie total would be approximately 284 calories. With richer ingredients and larger pour sizes, this can easily surpass 300 calories per serving. Variations of this recipe, sometimes called a "Flat White Martini," can have different ratios and brands, impacting the final caloric value.

How to reduce calories in your flatliner
For those watching their calorie intake, enjoying a flatliner in moderation or making some adjustments can help. Here are a few tips:
- Reduce the pour: Smaller servings, especially of the rich, creamy martini version, will significantly cut down calories. Simply split the drink with a friend.
- Use diet or sugar-free mixers: While not part of the traditional recipes, if you are creating a flatliner riff, using a zero-calorie or diet mixer can help. However, for a drink consisting primarily of alcohol, this won't help much.
- Opt for the shot: The sambuca and tequila shot version is naturally lower in calories than the creamy martini, making it the better choice for calorie counters. Just be mindful of the high alcohol content.
- Substitute with a lower-calorie spirit: For the shot, you could consider reducing the sambuca, which is quite high in sugar and calories compared to the tequila.
Conclusion
Ultimately, there is no single answer to how many calories are in a flatliner because two popular, distinct recipes share the same name. The spicy tequila shot is a leaner option, typically in the 100-225 calorie range per serving. In contrast, the decadent espresso martini version, loaded with creamy liqueurs, can easily top 300 calories. Your best approach is to clarify with your bartender which version you are ordering and understand the ingredients involved. Being aware of the different recipes is the key to managing your caloric intake when enjoying this potent cocktail.
