Rhubarb Old Fashioned​ Ingredients

For the Rhubarb Syrup

  • 1 cup rhubarb, chopped (fresh or frozen) – This tart vegetable adds a delightful zing to your cocktail.
  • 1 cup sugar (granulated) – Sweetens the syrup and balances the tartness of rhubarb beautifully.
  • 1 cup water – Necessary for dissolving the sugar and extracting flavor from the rhubarb.

For the Cocktail

  • 4 oz bourbon – Choose a good quality bourbon for a rich, smooth flavor in your Rhubarb Old Fashioned​.
  • 1 oz rhubarb syrup (homemade or store-bought) – This adds a unique twist to the classic drink, enhancing its complexity.

  • 4 twists orange peel (for garnish) – Adds a fragrant citrus note and visual appeal to your finished drink.

Step-by-Step Rhubarb Old Fashioned​

1. Combine the chopped rhubarb, sugar, and water in a saucepan. Bring to a boil over medium heat, watching for bubbles to form, then reduce to a simmer for about 10 minutes until the rhubarb softens.

2. Strain the mixture through a fine mesh sieve into a bowl or jar to remove the solids. Let the syrup cool completely; it should have a lovely pink hue and sweet-tart aroma.

For the Cocktail:

3. Mix in a cocktail shaker filled with ice, combine 4 oz of bourbon, 1 oz of your freshly made rhubarb syrup (or store-bought if you’re short on time), and 4 dashes of bitters.

4. Shake well for about 15 seconds until chilled and combined, feeling the cold through the shaker as you go.

5. Strain into a rocks glass filled with ice, pouring gently to keep things smooth and inviting.

Tips for the Best Rhubarb Old Fashioned​

  • Fresh vs. Frozen: Use fresh rhubarb whenever possible for a brighter flavor, but frozen works well if fresh isn’t available.
  • Straining is Key: Ensure you strain the syrup thoroughly; any solids can cloud your cocktail and affect its texture.
  • Adjust Sweetness: If you prefer a less sweet drink, reduce the sugar in the syrup or add more bitters to balance flavors in your Rhubarb Old Fashioned​.
  • Ice Matters: Use larger ice cubes in your rocks glass to keep your drink cold longer without excessive dilution.
  • Garnish Wisely: Twist the orange peel over the drink before adding it as a garnish to release essential oils that enhance aroma and taste.

How to Store and Freeze Rhubarb Old Fashioned​

  • Fridge: Store your Rhubarb Old Fashioned in an airtight container for up to 3 days. Keep it chilled to maintain its refreshing flavor and vibrant color.
  • Rhubarb Syrup: Homemade rhubarb syrup can be refrigerated in a sealed jar for about 2 weeks. Ensure it’s cooled completely before sealing.
  • Freezer: If you have leftover rhubarb syrup, pour it into ice cube trays and freeze for easy use later. It will last up to 6 months in the freezer.
  • Garnishes: Orange peels should be used fresh, but if stored in the fridge, they can stay good for about 1 day when wrapped tightly to prevent drying out.

Rhubarb Old Fashioned​ Your Way

Feel free to get creative and make this delightful cocktail truly your own with these fun variations!

  • Spicy Kick: Add a splash of ginger liqueur for a zesty twist. The warmth of ginger complements the tartness of rhubarb beautifully, creating a lively contrast that dances on your palate.
  • Citrus Burst: Swap orange peel for lemon peel to enhance brightness. The sharpness of lemon adds a refreshing zing that elevates the classic flavors, making each sip feel like summer.
  • Smoky Flavor: Use smoked bourbon to introduce a rich depth. This unexpected element transforms the drink, bringing an alluring complexity that pairs wonderfully with the rhubarb’s tartness.
  • Herb Infusion: Muddle fresh basil or mint leaves into the cocktail. These herbs infuse a fragrant note that harmonizes perfectly with the sweetness of the syrup, offering an aromatic experience with every sip.
  • Sweet Alternative: Substitute honey or agave syrup for granulated sugar in the rhubarb syrup. This natural sweetness lends a unique flavor profile while maintaining the cocktail’s delightful balance.
  • Berry Blend: Incorporate muddled strawberries or raspberries alongside the rhubarb syrup. This fruity addition introduces extra layers of flavor and a beautiful pop of color, perfect for special occasions.
  • Non-Alcoholic Version: Replace bourbon with non-alcoholic whiskey or your favorite sparkling water mixed with rhubarb syrup. You can still enjoy all those refreshing flavors without the alcohol, making it great for everyone!

Make Ahead Options

Preparing a Rhubarb Old Fashioned​ in advance is a delightful way to elevate your cocktail game while saving time for your next gathering. The rhubarb syrup, made from 1 cup of chopped rhubarb, 1 cup of sugar, and 1 cup of water, can be prepared up to 3 days ahead. Simply combine the ingredients in a saucepan, bring to a boil, then simmer for 10 minutes before straining out the solids and allowing it to cool. You can also measure out 4 oz of bourbon and have your bitters ready, ensuring everything is set for mixing. When you’re ready to serve, just shake the bourbon with the chilled rhubarb syrup and bitters in an ice-filled shaker, strain into a rocks glass filled with ice, and finish with orange peel twists for that fresh aroma. This way, you can enjoy a refreshing Rhubarb Old Fashioned​ without the last-minute rush!
