Ingredients
- 3 cups rhubarb, chopped into 2″ pieces
- 4 cups water
- 4 cups granulated sugar
- 1.5 oz vodka or gin, per serving (optional)
- 6 tbsp simple syrup, divided per glass

Tips & Variations
- Use fresh lemon juice to add brightness and balance the sweetness of the syrup for a more vibrant flavor.
- Try adding fresh mint leaves for a refreshing twist.
- Adjust the amount of simple syrup to taste, depending on how sweet you like your drinks.
- For a non-alcoholic option, skip the vodka or gin and increase the sparkling water slightly.
- Rhubarb ribbons can be made by peeling long strips with a vegetable peeler, adding an elegant touch to your drinks.
Storage
Store the rhubarb syrup in a sealed glass container in the refrigerator for up to 2 weeks. When ready to serve, mix the syrup with sparkling water and ice. The finished mocktail is best served fresh, as the sparkling water will lose its fizz if stored. Leftover cocktail or mocktail should be consumed soon after preparation for best taste.
