We were at a bar in Boston and were brought a cocktail with grapefruit and rosemary simple syrup. We were in love and pledged that we would bring this flavor combination to others. We use a healthy amount of rosemary so that lovely flavor comes through and helps to perfectly complement the tart, ruby-red grapefruit. Your customers will buy one bottle and then come back for 5 or 6 more. All-natural, with a long shelf life. We love this mixer with gin, vodka, rum, or, especially, sparkling wine (yay prosecco). Each 16 fl oz glass bottle makes 11+ drinks. Note: We use only glass bottles, and our shipping materials are made out of molded fiber pulp which is both highly effective at preventing damage and which can be either re-used, recycled, or even composted.
