Le Nouveau Moureaux

Use 2:1 demerara sugar syrup for its listed portion.

Chill a cocktail coupe in advance to ensure optimal serving temperature.

Fill a mixing glass with ice cubes to prepare for stirring.

Add the bourbon, Suze, and demerara syrup into the mixing glass, allowing the ingredients to meld over the ice.

Incorporate the grapefruit bitters, adding a complex aromatic dimension to the mix.

Stir the concoction gently yet thoroughly until the mixture is well-chilled and balanced.

Strain the mixture carefully into the pre-chilled cocktail coupe, ensuring a clean pour without ice shards.
