The tart rhubarb shrub and hints of rhubarb flavor in the Aperol play off each other really nicely in this drink. I used Four Roses Yellow Label Bourbon here, but plug in your favorite bourbon for mixing if you don't have Four Roses on hand.
Note: To make simple syrup, combine 1 cup water with 1 cup sugar in a small saucepan and heat over medium heat, stirring constantly, until sugar is dissolved. Cool before using. Simple syrup will keep in a sealed container in the refrigerator for up to 5 days.
- 3 ounces Four Roses Yellow Label Bourbon
- 1 1/2 ounces Rhurbarb Shrub
- 1 ounce Aperol
- 1 ounce simple syrup (see note)
- 1/2 ounce dry vermouth (such as Dolin)
Add bourbon, rhubarb shrub, Aperol, simple syrup, and vermouth to a cocktail shaker and fill with ice. Shake until well chilled, about 20 seconds. Strain into two coupe glasses and serve immediately.
