In a small saucepan, combine 1 cup water, 1 cup granulated sugar, and 4–5 fresh rosemary sprigs. Gently crush the rosemary with your fingers to help release the oils.
1 cup water, 1 cup granulated sugar, 4-5 sprigs fresh rosemary
Set the pan over medium heat and cook, stirring occasionally, until the sugar has completely dissolved and the mixture is just starting to steam. Do not boil vigorously.

Turn off the heat and let the rosemary steep in the hot syrup for 15–20 minutes. Taste at around 10 minutes and continue steeping if you prefer a stronger herbal note, but avoid letting it become bitter.
4-5 sprigs fresh rosemary
Strain the syrup into a jar, discarding the rosemary sprigs. Let it cool to room temperature, then cover and refrigerate until well chilled.
Roll the oranges and lemons on the counter to loosen the juice. Cut them in half and juice using a citrus juicer or reamer. Strain if you prefer a smoother drink with no pulp, then measure 1 1/2 cups orange juice and 1/4 cup lemon juice.
1 1/2 cups freshly squeezed orange juice, 1/4 cup fresh lemon juice
In a large pitcher, combine the orange juice, lemon juice, and 1/2 cup of the cooled rosemary syrup. Stir well.
1 1/2 cups freshly squeezed orange juice, 1/4 cup fresh lemon juice, 1/2-3/4 cup cooled rosemary syrup
Taste the mixture. If you prefer it sweeter, add more rosemary syrup a tablespoon at a time, up to about 3/4 cup total. Add 1–2 cups cold still water to adjust the intensity: less water for a stronger, juice-like drink and more water for a lighter, infused-water style drink.
1/2-3/4 cup cooled rosemary syrup, 1-2 cups cold water
Cover the pitcher and refrigerate for at least 1 hour so the flavors can meld and the base is thoroughly chilled.
When ready to serve, fill each glass with ice. For a cocktail version, add 1–1 1/2 oz vodka, gin, or tequila blanco to each glass, plus a splash of Cointreau or triple sec if desired.

Pour the chilled orange rosemary base into each glass until 2/3 to 3/4 full.
Top each glass with chilled sparkling water or club soda. Stir gently once so you don’t lose too much fizz.
2-3 cups sparkling water or club soda
Garnish each glass with an orange slice and a fresh rosemary sprig. Lightly clap the rosemary between your hands before adding it to release its aroma. Serve immediately.
