Rosemary Grapefruit Mocktail with a Sumac Salt Rim

When I stopped drinking alcohol, I realized how much I missed having something interesting to sip on during celebrations. I didn’t want juice or soda—I wanted layers of flavor, something that felt both sophisticated and thoughtful. Searching for that complexity, I found inspiration in a cherished childhood memory.

The scent of fresh grapefruit instantly transports me back to cozy holiday mornings of my childhood, when a family friend in Florida would ship a wooden crate of the most beautiful, fragrant pink grapefruits to our family on the East Coast — the whole house would smell like sunshine and citrus for weeks. Reflecting on that memory led me to create what is now my signature holiday drink.

This rosemary-grapefruit mocktail combines the bright flavors of fresh grapefruit and the refined complexity of a premium tonic. The rosemary adds an herbal, almost piney note that makes it feel extra festive, and the sumac rim isn’t just gorgeous to look at—it adds this tangy, citrusy punch that makes every sip more interesting.

Whether you’re taking a break from alcohol or simply want a refreshing, elevated drink that doesn’t leave you with a headache, this mocktail proves that complexity and elegance have nothing to do with what’s in your liquor cabinet.

Ingredients for Rosemary-Grapefruit Mocktails

This sophisticated mocktail combines simple, fresh ingredients to create something truly special. Here’s what you’ll need:

• Honey balances the tartness of the grapefruit juice and the bitterness of the tonic water, while its floral quality complements the rosemary. Look for a good-quality honey; orange blossom or wildflower varieties work especially well.
• Fresh rosemary infuses the honey syrup with an earthy, pine-like flavor that adds an herbal, sophisticated note to the mocktail, and sprigs are used in the final garnish.
• Fine sea salt: Just a pinch in the syrup enhances all the other flavors and helps balance the sweetness.
• Ground sumac: This beautiful burgundy-red spice has a tangy, lemony flavor that’s commonly used in Middle Eastern cooking. It adds a gorgeous color to the rim of the glass and a pleasant tartness that complements the grapefruit.

• Flaky sea salt: I love using Maldon or another flaky sea salt for the rim because the larger crystals add texture and a pleasant crunch. The salt balances the sweetness of the honey syrup and enhances the citrus flavors.
• Pink grapefruit: A wedge moistens the rim of the glass so the sumac-salt mixture sticks, a wheel is used for garnish, and the freshly squeezed juice gives the drink its beautiful rosy color.
• Tonic water: I recommend using a premium tonic water like Fever-Tree or Q Tonic. They have a clean, botanical flavor and are less sweet than mainstream brands, which lets the other ingredients shine.

How to Make Rosemary-Grapefruit Tonic

This elegant mocktail is easier to make than it looks. Here’s how:

• Make the rosemary-honey syrup: In a small saucepan, combine the water, honey, fresh rosemary sprigs, and a pinch of fine sea salt. Set over medium heat and stir until the honey dissolves completely. Bring to a gentle simmer, then reduce the heat to low and simmer, stirring occasionally. Remove from the heat and let the syrup cool to room temperature. The rosemary will continue to infuse as it cools, so don’t skip this step. Once cooled, strain the syrup through a fine-mesh strainer into a jar or bowl, pressing on the rosemary with the back of a spoon to extract maximum flavor. Discard the rosemary.
• Prepare the sumac rim: On a small plate, combine the ground sumac and flaky sea salt, stirring to mix evenly. Run a grapefruit wedge around the rim of each glass to moisten it, then dip the rim into the sumac-salt mixture, rotating to coat evenly. Set the rimmed glasses aside.
• Mix the mocktails: Fill each rimmed glass with ice cubes. Add the rosemary-honey syrup to each glass. Start with less and taste—you can always add more if you prefer it sweeter. Pour the fresh pink grapefruit juice into each glass, then top with tonic water per glass. Stir gently to combine, being careful not to disturb the sumac rim.
• Garnish and serve: Garnish each glass with a fresh rosemary sprig and a pink grapefruit wheel. Serve immediately while the tonic is still fizzy and refreshing.

To Make a Big Batch

To make a pitcher for a crowd, combine all the rosemary-honey syrup (about 3/4 cup) with the 2 cups of grapefruit juice in a pitcher and refrigerate.

When ready to serve, rim the glasses, fill with ice, pour in the grapefruit-syrup mixture (about 1/2 cup per glass), and top with tonic water (about 1/3 cup per glass).

What is Tonic Water?

Tonic water is carbonated water flavored with quinine, a bitter compound that gives it a distinctive taste. This, along with sugar, sets it apart from club soda or seltzer, which are just fizzy water.

The bitterness of tonic water is essential in this mocktail—it balances the sweetness of the honey syrup and complements the tart grapefruit. If you substitute plain sparkling water, you’ll lose that sophisticated, bitter-sweet flavor that makes this so cocktail-like.

Make It Your Own

This recipe is quite flexible and easy to customize. Here are some variations:

• Adjust the sweetness: Start with less syrup and add more to taste. Grapefruit sweetness varies, so you may need more or less depending on your fruit.
• Use different citrus: If you can’t find pink grapefruit, regular white grapefruit works fine—just be aware it will be more tart. You can also try a mix of grapefruit and orange juice for a sweeter, more approachable flavor.
• Change the herbs: If rosemary isn’t your favorite, try fresh thyme or lavender instead. Both pair beautifully with grapefruit.
• Skip the sumac rim: If you don’t have sumac, you can rim the glasses with just flaky sea salt, or skip the rim entirely. The drink will still be delicious.
• To make it a Cocktail: Add 1 1/2 ounces of gin or vodka to each glass along with the rosemary-honey syrup and grapefruit juice. Stir well before topping with tonic water and garnishing.
