Chill a coupe glass in the freezer for about 10 minutes or fill it with ice water while preparing the drink.
Add the brandy, sweet vermouth, and Angostura bitters to a mixing glass.
Fill the mixing glass with fresh large ice cubes until nearly full.
Stir gently for 20–25 seconds until the outside of the glass feels very cold and slightly frosty.
Empty the chilled serving glass if you used ice water, then strain the cocktail into the glass. The drink should look clear and glossy.
Garnish with a Luxardo cherry. For extra aroma, twist an orange peel over the drink before serving, then discard or place it in the glass.
