Add 1/2 cup water, 1/4 cup honey or sugar, and 3–4 rosemary sprigs to a small saucepan. Warm over medium heat, stirring gently, just until the sweetener is fully dissolved and the mixture is steaming but not boiling. Turn off the heat and let the rosemary steep for 15–20 minutes; the longer it sits, the stronger the herbal flavor.
1 cup water, 1/4 cup honey or granulated sugar, 3-4 sprigs fresh rosemary
Remove the rosemary sprigs and strain the syrup through a fine-mesh sieve into a jar or heatproof bowl. Let it cool to room temperature, then chill briefly in the refrigerator so it is cool before mixing the drink.
1/4 cup honey or granulated sugar, 3-4 sprigs fresh rosemary
While the syrup steeps and cools, cut the oranges in half and juice them using a citrus juicer or by hand. Measure out 1 cup of orange juice. Strain out most of the pulp if you prefer a smoother drink, or leave it in for more texture.
1 cup freshly squeezed orange juice
In a medium pitcher, combine 1 cup orange juice, the cooled rosemary syrup, the remaining 1/2 cup water, and 1/2–1 tablespoon fresh lemon juice. Add a tiny pinch of salt if using. Stir well and taste, adjusting sweetness with a bit more honey or sugar if desired, or diluting with a splash more water if it tastes too strong.

Cover the pitcher and chill in the refrigerator for 20–30 minutes to allow the flavors to meld and ensure the drink is very cold. If you are short on time, you can skip this step and use extra ice when serving.
Just before serving, pour 1–1 1/2 cups chilled sparkling water or club soda into the pitcher. Stir gently to combine without knocking out all of the bubbles. Start with 1 cup and add more for a lighter, less sweet drink.

Fill glasses with ice. Pour the orange rosemary drink over the ice, leaving a little room at the top. Garnish each glass with an orange slice and a fresh rosemary sprig. Lightly clap the rosemary sprig between your hands before adding it to release its aroma. For a cocktail, add 1–1 1/2 ounces of your chosen spirit to each glass before topping with the drink.

For a large gathering, mix the orange juice, rosemary syrup, water, and lemon juice in a dispenser and keep chilled. Let guests top off their glasses with sparkling water (and optional spirits) so each serving stays fresh and fizzy.
