Shake all ingredients except Champagne with ice in a cocktail shaker. Strain into a coupe glass and top with 3 Parts of Champagne. Garnish with a Demerara sugar rim and twist of orange zest.
*To create allspice-infused demerara syrup, add 1/2 tsp of ground allspice to a saucepan for every 3 cups of demerara rich syrup. Simmer over medium heat for 10 minutes, and rest for 5 minutes. Strain mixture through a cheesecloth to remove excess.
Bring bright and vibrant flavor to your favorite tequila cocktails at home.
