Place the bourbon, sweet vermouth, honey and sage leaves in the bottom of a cocktail shaker. Muddle with a muddler or back of a spoon to mix ingredients.

Add the orange juice to the shaker. Fill with ice halfway. Shake for 30 seconds until well combined.

Fill a rocks glass with fresh ice and strain mixture into the glass (either through the top of the cocktail shaker or a small strainer).

Garnish with a sage leaf.
