First Whistle
About
First Whistle is a refreshing tequila cocktail created for the excitement of tournament season. Bright, citrus-forward, and incredibly easy to drink, it captures the energy of those moments just before the action begins.
Tequila provides the foundation with its crisp agave character and clean finish. Unlike heavier spirit-forward cocktails, First Whistle keeps things light and refreshing, making it a great choice for daytime celebrations, watch parties, and outdoor gatherings.
Fresh grapefruit juice brings a vibrant citrus flavor with a balance of sweetness and gentle bitterness. It delivers the bright, lively character that defines the cocktail while adding a refreshing edge that keeps each sip interesting.
Agave syrup rounds out the drink by softening the grapefruit's sharper notes and enhancing the natural agave flavors already present in the tequila. The result is a cocktail that feels balanced, approachable, and refreshing from start to finish.
Simple ingredients, clean flavors, and a bright finish make First Whistle the perfect way to kick off game day celebrations.
Shaken or Stirred? Shaken. Grapefruit juice and agave syrup need a proper shake to blend seamlessly with the tequila. Shaking also chills the cocktail quickly and creates a smoother, more refreshing finish.
