Bourbon smashes are delicious on a hot summer day, but this cocktail isn't a smash cocktail in large part because of its lack of fresh herbs. Similar to a mint julep, a blackberry bourbon smash contains a lot of mint leaves. Crushing that fresh mint gives the cocktail an entirely different flavor than what this recipe has. Which is also why this drink doesn't have a mint sprig for garnish. This delicious recipe is the perfect way to enjoy a cozy (or spooky!) fall night. A whiskey smash or bourbon smash is better for a warmer time of year.
