Most people tracking protein don't think twice about cocktails — but the mixers, dairy, and egg whites in many drinks can add a surprising amount of protein. A creamy White Russian or an egg-white whiskey sour contributes several grams per glass, while a vodka-soda adds almost none. This calculator helps you estimate the protein content in your favorite cocktails so you can log drinks accurately and stay on top of your daily macros.
Choose a preset cocktail for a quick estimate, or use the custom ingredient builder to calculate the protein from the exact dairy or egg component in your drink. Adjust the number of drinks and serving size to match your actual glass, and the tool will show total protein, per-drink values, and a simple breakdown.
Keep in mind that the results are estimates. Recipes and pour sizes vary from bar to bar, so treat the numbers as a practical guide rather than a laboratory measurement.

How to Use This Calculator
- Select a cocktail from the preset dropdown, or choose 'Custom ingredient builder' if your drink isn't listed.
- For a custom estimate, pick the protein source (whole milk, half and half, heavy cream, coconut cream, Greek yogurt, or egg white) and enter the amount in fluid ounces or whole egg whites.
- Enter the number of drinks you plan to have. The default is 1.
- Choose a drink size factor. Standard is based on typical published recipes; use 'Larger' or 'Double' for generous bar pours and 'Smaller' for a short or half-recipe drink.
- Click 'Calculate Protein' to see total protein, protein per drink, and the exact calculation breakdown.
Where Cocktail Protein Actually Comes From
Spirits — vodka, gin, rum, tequila, whiskey — are distilled and contain essentially no protein. The same is true for most liqueurs. In a cocktail, protein comes almost entirely from the non-alcoholic ingredients: milk, cream, coconut cream, yogurt, egg whites, and occasionally nut milks or fruit juices.
The table below lists approximate values for common cocktail protein sources.
| Ingredient | Protein per serving |
|---|---|
| Whole milk | 1.0 g per 1 fl oz |
| Half and half | 0.8 g per 1 fl oz |
| Heavy cream | 0.6 g per 1 fl oz |
| Coconut cream | 0.6 g per 1 fl oz |
| Greek yogurt | 2.9 g per 1 fl oz |
| Large egg white | 3.6 g per egg white |
Values are based on USDA FoodData Central entries for common dairy and egg products. Bar recipes can use different brands or fat percentages, so actual numbers vary by a small amount. You can browse the official database at USDA FoodData Central for more detailed nutrient profiles.
How the Estimate Is Calculated
For the custom builder, the calculation is simple: protein per drink equals ingredient protein-per-serving multiplied by the number of servings, multiplied by the drink size factor. Then multiply by the number of drinks to get the total.
For presets, each drink has a typical protein value based on common published recipes. The value reflects the dairy, egg, or coconut component in that standard recipe, not the alcohol itself.
Sample Results for Popular Cocktails
| Cocktail | Approximate protein per standard drink |
|---|---|
| White Russian | 3.2 g |
| Whiskey Sour (with egg white) | 3.6 g |
| Brandy Alexander | 2.5 g |
| Piña Colada | 1.8 g |
| Mudslide | 6.0 g |
| Eggnog | 8.5 g |
| Bloody Mary | 1.2 g |
| Espresso Martini | 0.4 g |
| Margarita | 0.2 g |
| Gin and Tonic | 0.1 g |
These are rough averages. A 'skinny' White Russian made with almond milk will have far less protein, while a heavy-pour mudslide served in a tall glass can have more.
Tips for Raising or Lowering Protein in Cocktails
- Boost protein: Swap cream for Greek yogurt in creamy drinks. One ounce adds about 2.9 g protein, and it blends well in frozen cocktails.
- Use egg whites: A classic whiskey sour or gin fizz with one egg white adds about 3.6 g protein and creates a lovely foam.
- Choose milk over juice: In tiki-style drinks, replacing part of the fruit juice with milk or coconut cream changes the protein slightly. Coconut cream adds around 0.6 g per ounce.
- Keep it low: If you want almost no protein, stick with spirits and zero-calorie mixers, or a simple gin and tonic. These drinks typically contain under 0.5 g.
- Watch portions: The single biggest variable in bar nutrition is how much is poured. A 12 oz cocktail with double cream delivers roughly double the protein estimate.
Frequently Asked Questions
Q: Does alcohol itself contain protein? A: No. Distilled spirits contain virtually zero protein, fat, and carbohydrates. The calories come from ethanol.
Q: Why does the same cocktail have different protein at different bars? A: Recipes, brands, cream fat content, egg sizes, and pour sizes all differ. A bar using half-and-half instead of heavy cream, or a larger egg white, will change the result by a gram or more.
Q: Can I use this calculator for non-alcoholic mocktails? A: Yes. Just use the custom ingredient builder or select a preset and note that the alcohol does not affect the protein calculation. The estimate will still be accurate for the dairy or egg component.
Q: Should I log the protein from cocktails? A: If you track macros for weight management or athletic performance, yes. Every gram counts, and creamy drinks can add 5–10 g to your daily intake without you noticing.
Q: Where do the reference values come from? A: Ingredient values are based on USDA FoodData Central, and cocktail averages are compiled from standard published recipes. Use them as reasonable approximations.
