Tasting Notes

The Blue Grapefruit Cosmopolitan is a refreshing and vibrant cocktail with a perfect balance of sweet, tart, and citrus flavors. Vodka creates a clean base, while Blue Curaçao adds a subtle orange sweetness and a brilliant blue color. A touch of grenadine not only brings a hint of pomegranate sweetness but also creates a beautiful layered color effect. Grapefruit juice adds a refreshing citrus bite that balances the sweetness, and simple syrup smooths everything out for an easy-drinking cocktail. Bright, bold, and refreshing, this drink is as fun to look at as it is to sip.

Equipment and Glassware

Use a cocktail shaker to mix and chill the ingredients thoroughly. A jigger ensures accurate measurements for a balanced flavor. Strain the drink into a chilled martini or coupe glass to showcase the bright color and smooth presentation. Have a bar spoon on hand if you want to create a layered effect with the grenadine. A citrus press or reamer will help you get the freshest grapefruit juice for the best flavor.
