Let’s make a Revolver! 🔫 The Revolver is a caffeinated variation on the Manhattan, swapping the Sweet Vermouth for coffee liqueur. First introduced by Jon Santer in the early 2000s (in San Francisco at the famous Bourbob & Branch), the cocktail has risen to stardom in recent years. Famously made with Bulleit bourbon, you can easily swap for the Bourbon of your choice—though the Bulleit/Bullet homophone is a great reason to stick with the classic whiskey. It’s a delicious spirit-forward cocktail
