At the first sight of fresh spring rhubarb, I start craving this Rhubarb Cocktail. It’s gently spiked with rum, a little bit tart, a little bit sweet and herbaceous, and entirely refreshing.

As a rule, we’re red wine people. But it’s fun to have an occasional cocktail, usually of the gin variety in our house: a good martini with olives or a gin and tonic (with homemade tonic water). So I’m not sure why this drink caught my eye in a long ago issue of Bon Appétit magazine. Maybe it was that pretty sprig of rosemary poking out of the top. Whatever it was, I made it, and we’ve had it every year since when the scarlet stalks of rhubarb appear at the grocery store or farmer’s market.

Ingredients You Need for this Rhubarb Cocktail

  • Fresh Rhubarb: Look for the reddest stalks you can find.
  • Fresh Rosemary: Dried rosemary is not a good substitute here.
  • Lemons: Look for brightly colored, firm lemons that are heavy for their size.
  • Sugar: Granulated white sugar, superfine if you have it.
  • Water: Ideally filtered for making rosemary infused simple syrup.
  • Rum: White rum for its mild (not spiced) flavor profile and clear color. Vodka or a London dry gin or Plymouth gin would also be excellent.

It’s not just the raw rhubarb with its floral notes and pleasantly sour flavor or the perky, earthy hint of rosemary that I love in this delicious cocktail. It’s also lively, not too sweet, and one recipe makes the perfect amount for a party. Fill a pitcher to share with friends. Serve it over ice or stir in cocktail shaker with ice to serve up in a martini glass.

Look for the reddest stalks of rhubarb you can find so you’ll end up with cocktails that are a pretty pink color instead of murky green ones (though they’d still be tasty). And make sure to start this recipe at least 4 hours or up to a day before you plan to serve.

  • Add diced rhubarb, 1 tablespoon lemon juice, 1 1/4 cups water, and 1/4 cup sugar to a blender. Blend into a coarse puree.

    I have made this cocktail and love it. I like to cook the rhubarb, sugar and water together creating a base syrup. I then freeze it in small containers. I do the same with the rosemary simple syrup. When you want a cocktail, just thaw slightly, blend or put it in a shaker with the rum and lemon juice and voila! Beautiful cocktail!

      Glad you’re enjoying this recipe, Shelley!

    Hi Marissa.Remember me from BFC?..I love love love the drink. Finally did the round up on my blog.. Thanks so much! Can’t wait to make it 🙂 although I might have to really look for rhubarb…any alternative??

    1. Marissa says:

      Hi there, I’ve seen fresh cranberries suggested as a substitute. Thanks so much for including me in your cocktail roundup!

  3. Sophie-Lee says:

    Wow, this looks amazing! Have you tried storing the syrup for a longer time, or does it pretty much need to consumed within 2 days? Seems to have enough sugar that it would preserve well.

    1. Marissa says:

      Honestly, I’ve wondered the same thing. I see no reason why it wouldn’t last a bit longer – maybe a week?

  4. Lorraine @ Not Quite Nigella says:

    What a gorgeous looking cocktail! Love the little sprig of rosemary and also a nice idea to use pink rhubarb if you’re doing a pink themed party too 🙂

  5. Paula @ Vintage Kitchen Notes says:

    I really hate that I don´t find rhubarb here, not even in the asian market that has every thing needed for every type of cuisine. Maybe next spring luck will be on my side.
    I love daiquiris, even though the frozen version gave them a bad rep. Not for me! And I never used rosemary in one. Very interesting flavors Marissa! No wonder you love it.
