Add the Belvedere organic vodka, freshly squeezed lime juice, freshly squeezed grapefruit juice, simple syrup, elderflower liqueur, and orange bitters into a cocktail shaker.

Fill the shaker with ice (about 1 cup) and shake vigorously for 12–15 seconds, until the shaker is very cold to the touch and the exterior shows condensation.

Discard ice or water from the chilled glass. Fine-strain the shaken cocktail into the chilled coupe or Nick & Nora glass to remove small ice chips and any pulp.

If you prefer a slightly effervescent finish, gently top with about 1 oz club soda and stir once with a bar spoon to combine; otherwise serve neat.

Garnish & Finish

Express the grapefruit twist over the drink by holding it skin-side down and giving it a firm twist to spray oils onto the surface, then rub the rim with the twist and drop it into the glass.

Optionally slap the mint sprig between your palms once to release aromatics and place it on the drink as a finishing aromatic garnish.

Serve immediately.
