Steps to Prepare Your Rosemary Drink

Prepare the Rosemary: Rinse a few sprigs of fresh rosemary under cold water and pat them dry. Lightly bruise the leaves to release the essential oils, which will intensify the flavor in your drink.
Infuse the Base: In a pitcher, combine your chosen drink base with the rosemary sprigs. If you prefer a sweetened beverage, add your desired amount of sweetener to blend the flavors well.
Let It Sit: Allow the mixture to infuse for at least an hour in the refrigerator. The longer it sits, the more pronounced the rosemary flavor will be.
Serve: Remove the rosemary sprigs and pour the infused beverage into glasses. For an extra refreshing twist, add fresh slices of citrus like lemon, lime, or orange.
