Rhubarb Old-Fashioned

Makes 1 cocktail


For the rhubarb simple syrup:

1 cup water

1 cup sugar

1 cup chopped rhubarb stalk

For the cocktail:

2 ounces bourbon

1 ounce rhubarb simple syrup

2-4 dashes angostura bitters (depending on your taste)

Additional rhubarb stalk for garnish (optional)


  1. First, make the simple syrup. Combine all syrup ingredients in a small saucepan and bring to a heavy simmer. Turn down to a low simmer and let cook until rhubarb has broken down and mixture has reduced by half (about 10-15 minutes.)

  2. Strain the syrup through a sieve and into a resealable bottle or container to get rid of chunks, and allow to cool to at least room temperature.

  3. Once simple syrup is cool, make the cocktail. In a cocktail shaker filled halfway with ice, combine the bourbon, simple syrup and angostura bitters. Shake vigorously for about 15 second and then strain into a rocks glass filled to the brim with ice.

  4. Garnish with a long piece of rhubarb stalk, if desired.
