An espresso martini is a sophisticated and energizing cocktail, but its delightful flavour can mask a surprisingly high alcohol content. The number of alcohol units in this popular drink varies considerably, making it crucial to understand the factors involved, particularly when aiming for mindful drinking. While some recipes suggest a count around 1.5 units, others push the total closer to 3 or more depending on measures and ingredients.
Calculating Alcohol Units: The Core Formula
To accurately determine the alcohol units in any drink, especially a cocktail with multiple alcoholic components, you need a simple formula. In the UK, one unit is defined as 10ml of pure alcohol.
The formula to calculate units is:
Strength (ABV%) x Volume (ml) ÷ 1,000 = Units
How to Apply the Formula to an Espresso Martini
To use this formula for an espresso martini, you must calculate the units for each alcoholic ingredient separately and then add them together. This requires knowing the specific volumes and alcohol by volume (ABV) percentages of the vodka and coffee liqueur in your recipe. For example, if you use a 40% ABV vodka and a 20% ABV coffee liqueur, the calculations will be as follows:
- Units from Vodka:
[Volume of Vodka (ml) x 40] ÷ 1000 - Units from Coffee Liqueur:
[Volume of Coffee Liqueur (ml) x 20] ÷ 1000 - Total Units: Add the two results together.
The Classic Recipe: The IBA Standard
The International Bartenders Association (IBA) provides a standard recipe that offers a good benchmark for a classic espresso martini. The IBA's recipe calls for specific measures, which can be used to perform a unit calculation.
-
Ingredients:
- 50 ml Vodka (approx. 40% ABV)
- 30 ml Coffee Liqueur (approx. 20% ABV)
- 10 ml Sugar Syrup
- 1 strong Espresso
-
Calculation:
- Vodka:
(50 ml x 40) ÷ 1000 = 2.0 units - Coffee Liqueur:
(30 ml x 20) ÷ 1000 = 0.6 units - Total:
2.0 + 0.6 = 2.6 units
- Vodka:
Based on the IBA recipe, a standard espresso martini contains approximately 2.6 units of alcohol. This is a significant amount and represents a large portion of the weekly recommended intake of 14 units.
Beyond the Classic: Factors That Alter the Unit Count
The unit count of an espresso martini is highly susceptible to variations in ingredients and proportions. Several factors can either increase or decrease the final unit count of your cocktail.
- Proportions: A heavy-handed bartender or a DIY home mixologist pouring larger measures will drastically increase the units. For example, a 60ml pour of vodka instead of 50ml would add another 0.4 units.
- Alcohol Strength (ABV): Not all brands are created equal. Some coffee liqueurs, like Mr Black, have a higher ABV than Kahlua, while different vodkas can also have varying strengths. Opting for a lower ABV spirit or liqueur is a simple way to reduce the units.
- Ingredient Substitutions: Craft cocktails often feature creative variations. Switching the base spirit from vodka to a different liquor like whiskey or rum (as seen in The Nightwatchman and tiki-style versions) will change the overall ABV and flavour profile. Using non-alcoholic spirits will, of course, reduce the units to zero.
- Dilution: While not an alcoholic ingredient, dilution from shaking with ice affects the final ABV of the liquid in the glass. However, for a simple unit count, it's easier to focus on the starting alcoholic volumes, as they represent the total alcohol ingested.
Recipe Variations and Their Unit Impact
Different recipes yield different results, highlighting the importance of knowing what’s in your glass. Here is a comparison of how different recipes can alter the unit count:
| Recipe | Vodka (40% ABV) | Coffee Liqueur | Estimated Units | Notes |
|---|---|---|---|---|
| IBA Standard | 50 ml | 30 ml (20% ABV) | ~2.6 units | Official benchmark recipe. |
| RecipeTin Eats | 40 ml | 20 ml Kahlua (20% ABV) | ~2.0 units | Lower total volume, resulting in fewer units. |
| Volcano Coffee Works | 0 ml | 60 ml Mr Black (25% ABV) | ~1.5 units | Removes vodka, relies solely on a lower-sugar liqueur. |
| Difford's Guide | 45 ml | 22.5 ml Kahlua (20% ABV) | ~2.2 units | Uses a balanced, slightly smaller measure for a crisp flavour. |
| Double Pour | 100 ml | 60 ml Kahlua (20% ABV) | ~5.2 units | Dangerous for mindful drinking, easily happens with generous pours. |
Staying Safe: Tips for Mindful Consumption
Considering the significant alcohol content, particularly in generously poured versions, it's wise to practice mindful drinking. Here are some tips to help manage your intake:
- Be Aware of What You're Drinking: Don't assume a cocktail is 'weaker' than a straight spirit. The sweetness and caffeine in an espresso martini can mask the effects of the alcohol, making you feel less intoxicated than you are.
- Measure Your Ingredients: If making an espresso martini at home, use a jigger to accurately measure your spirits and liqueurs. Avoid free-pouring, as it often leads to a higher unit count than intended.
- Track Your Intake: Keep a log of your drinks or use a unit calculator to stay on top of your weekly alcohol consumption. Resources like the unit calculator on Alcohol Change UK can be very helpful.
- Pace Yourself: Alternate alcoholic drinks with soft drinks or water. This helps to slow down your alcohol intake and keeps you hydrated.
- Choose Lower-ABV Options: Opt for versions of the cocktail made with a lower-proof coffee liqueur or replace some of the vodka with a non-alcoholic spirit alternative to reduce the overall unit count.
Conclusion: Know What You're Drinking
The units in an espresso martini are not a fixed quantity but a variable figure that changes with the recipe and pour size. A standard, professionally mixed IBA recipe contains approximately 2.6 units, while more generous or stronger variants can easily exceed 3 units. By understanding the simple unit calculation formula and the factors that influence the final count, you can make more informed choices about your consumption. This knowledge allows you to continue enjoying the iconic cocktail responsibly, whether you are at home or out on the town.

Know Your Units: Essential Takeaways
- Calculation is Key: The number of units in an espresso martini is not fixed and must be calculated based on the specific recipe and measurements used.
- Variations are Common: Recipes differ, with factors like the volume of vodka and the ABV of the coffee liqueur directly impacting the final unit count.
- Standard Recipe is Strong: A classic IBA-style espresso martini, using 50ml vodka and 30ml coffee liqueur, typically contains around 2.6 units.
- Beware of Generous Pours: At home or in a bar, a heavy-handed pour can push the total units significantly higher than a standard measure.
- Caffeine Can Be Misleading: The stimulant effect of the espresso can mask the depressant effect of the alcohol, making you feel less intoxicated than you actually are.
- Drink Responsibly: Alternating with soft drinks, measuring carefully, and being aware of the unit count are essential for mindful consumption.
Frequently Asked Questions
Q: Is an espresso martini a strong cocktail? A: Yes, an espresso martini is considered a strong cocktail. The combination of vodka and coffee liqueur results in a high alcohol content, often exceeding 20% ABV for the final liquid.
Q: How many units is a standard shot of spirits? A: In the UK, a standard single pub measure of spirits (25ml) at 40% ABV counts as 1 unit. Many recipes call for double this amount or more.
Q: Does adding more simple syrup affect the unit count? A: No, adding more simple syrup does not change the number of alcohol units, as it is non-alcoholic. However, it can increase the sugar content and overall volume, which might slightly decrease the final ABV percentage of the drink.
Q: How can I make a lower-unit espresso martini? A: To reduce the units, you can use less vodka, choose a coffee liqueur with a lower ABV (like Mr Black mentioned in one source), or replace some of the alcohol with a non-alcoholic spirit alternative.
Q: What is a safe amount of alcohol to drink per week? A: The UK's Chief Medical Officers advise that both men and women should not regularly drink more than 14 units of alcohol a week. It is also recommended to spread this consumption evenly over three or more days.
Q: Is there a calculator to figure out my cocktail's units? A: Yes, several online tools can help. Alcohol Change UK offers a unit calculator that can be helpful for assessing your intake based on different drink types and volumes.
Q: Why do recipes differ so much in their unit count estimates? A: The difference stems from the various measurements and brands used. Bartenders and home cooks may use different ratios or products with varying ABVs, leading to a wide range of unit counts for the same cocktail type.
