On The Rocks (OTR) Spiced Pear Whiskey Sour is a limited-release cocktail that combines Old Overholt rye whiskey, pear, citrus, and cinnamon. It’s a modern take on the classic whiskey sour, with a balance of sweet and spicy flavors. The 375 ml bottle contains 20% alcohol by volume and is shelf stable, so it can be enjoyed anywhere without needing to be chilled. OTR recommends pouring the cocktail over ice and garnishing with a pear slice and cinnamon sticks.
