Tasting Notes
The Rhubarb Bourbon Sour brings together the tart edge of rhubarb with the warmth of bourbon for a cocktail that’s bold but balanced. The lemon juice brightens the drink and accentuates the tang of rhubarb, while the simple syrup smooths out any sharpness. The bourbon provides a deep, oaky backbone with subtle vanilla and spice notes. This drink leans into the contrast between sweet and sour, offering a crisp, citrusy opening that rounds out into a mellow finish. It’s refreshing yet sturdy, perfect for fans of both classic sours and seasonal flavors.
Equipment and Glassware
To make a Rhubarb Bourbon Sour, you’ll need a cocktail shaker, a jigger for measuring, and a strainer. A citrus squeezer is helpful for fresh lemon juice. Use a coupe glass or a small rocks glass depending on whether you prefer it served up or on ice. If garnishing with a rhubarb ribbon or twist, a vegetable peeler or sharp knife will help. For best results, chill your glass before pouring to maintain the drink’s ideal temperature. This setup allows for efficient mixing and a clean, smooth pour.
