Nutrition values are calculated estimates for the listed ingredients, preparation, and serving size. Ingredient brands, substitutions, preparation, and serving size can change the result.
Calculation assumptionsTwo fluid ounces of 40% ABV gin and four ounces Fever-Tree Premium Indian Tonic Water are counted. Its UK label supplies tonic carbohydrate and sugar; ice and garnish are excluded.
Serving basis: The calculated batch is divided into 1 equal serving.
Finished yield: 6 fl oz liquid before ice dilution.
Estimated alcohol: about 1.3 U.S. standard drinks. Approximately 130 calories come from ethanol at 7 kcal per gram.
Method: Nutrition is estimated from listed mass quantities or the stated label-volume basis, preparation, and cited composition data. A label-volume equivalent is not a measured gram weight. Actual values vary by brand, produce size, preparation method, and serving yield.
Quality check: database or declared-label energy is checked against macro-derived energy. Variances above 8% are blocked for review unless a documented food-specific or rounding explanation has been approved.
