Bitter Grapefruit

Chill a martini glass in advance to ensure optimal serving temperature.

Prepare a twist of grapefruit zest to use as a garnish.

Combine Ketel One Vodka, Aperitivo Luxardo, Strucchi Rosso Vermouth, and freshly squeezed pink grapefruit juice in a cocktail shaker.

Add ice to the shaker and shake vigorously until well chilled.

Fine strain the mixture into the pre-chilled martini glass.

Express the grapefruit zest over the cocktail to release its oils, then garnish the drink with the zest twist.
