Short answer: a classic espresso martini — vanilla vodka, Kahlúa, and fresh espresso — runs about 190 calories, and closer to 230 when it's finished with simple syrup. Spark Plug's canned nitro espresso martini is 150 calories per serving. Here's the side-by-side.
Spark Plug vs. a classic espresso martini
Same real coffee, the same full 20% ABV as a bar pour, the same crema — Spark Plug simply comes in lighter, because there's no coffee-cream liqueur and no stacking of liqueur on top of syrup.
| Classic bar recipe | Spark Plug | |
|---|---|---|
| Serving size | ~4.5 oz | 3.5 oz |
| Calories | ~190 (up to ~230 with syrup) | 150 |
| Sugar | ~15 g (up to ~25 g) | 8 g |
| Fat | 0 g (dairy versions add it) | 0 g |
| ABV | ~18–22% | 20% |
| Dairy | None (creamy versions add it) | Dairy-free |
| Crema | From a hard shake, fades fast | Nitrogen — builds every pour |
A full 200ml can of Spark Plug pours two of those servings — 300 calories total — and carries about 80–100 mg of caffeine, roughly one cup of coffee. It's dairy-free and gluten-free, with the crema coming from nitrogen rather than cream. Here's how the nitro crema actually works.
Why a classic espresso martini adds up
Most of the calories in an espresso martini come from the sweeteners, not the coffee or the vodka. Here's a typical bar pour, by the numbers:
| Ingredient | Amount | Calories | Sugar |
|---|---|---|---|
| Vanilla vodka (40% ABV) | 1.5 oz | ~98 | 0 g |
| Kahlúa (coffee liqueur) | 1 oz | ~91 | ~15 g |
| Fresh espresso | 1 oz | ~1 | 0 g |
| Total | ~4.5 oz | ~190 | ~15 g |
Figures from brand labeling and standard nutrition data: Kahlúa ~91 cal/oz, vanilla vodka (e.g. Absolut Vanilia, Smirnoff) ~98 cal per 1.5 oz, espresso ~1 cal/oz.
The coffee liqueur does most of the work: Kahlúa is roughly a third sugar, so a single ounce carries ~15 g of sugar and ~91 calories. Add a half-ounce of simple syrup — as many bar recipes do — and the drink climbs toward 230 calories and 25 g of sugar. Spark Plug lands at 150 calories and 8 g of sugar, with none of the dairy a creamy version brings.
