Fresh Rosemary Syrup

Store in a sealed glass bottle in the refrigerator for up to one month. Keep refrigerated.

Monitor the steeping time closely — rosemary releases its aromatic oils quickly but also releases bitter, camphor-like compounds from the stems and resinous parts of the leaves if steeped too long. A steeping time of ten to fifteen minutes off the heat after simmering is the sweet spot; taste at ten minutes and strain immediately if the flavor is right. Fresh rosemary with vibrant, fragrant needles produces a far superior syrup to old, dried rosemary from a spice jar — the volatile oils that create rosemary's distinctive character degrade significantly with age and drying. Avoid including large amounts of rosemary stems; the needles carry the best flavor.

Rosemary (Salvia rosmarinus) is native to the Mediterranean region and has been used in both cooking and as an aromatic herb since ancient times — it was regarded in ancient Greece and Rome as a symbol of memory and was used in ceremonial garlands and medicinal preparations. The herb has been a staple of European cooking for centuries, particularly in Italian, Spanish, and Provençal cuisines where it pairs naturally with lamb, roasted vegetables, and olive oil. Rosemary's entry into the craft cocktail canon came through the broader herb garden movement of the 2000s, when bartenders began systematically translating culinary herbs into cocktail syrups and garnishes. Rosemary's piney, resinous character proved particularly complementary to gin's botanical profile and to grapefruit, leading to its frequent appearance in gin-and-tonic variations, White Lady riffs, and the Rosemary Gimlet that became a fixture on craft menus.

A rosemary-grapefruit syrup can be made by adding the zest of one Ruby Red grapefruit to the warm syrup after straining and steeping for ten minutes — this creates a citrus-herbal syrup that is outstanding in gin and tequila cocktails. A rosemary-honey syrup, using honey in place of white sugar, produces a warmer, more aromatic sweetener excellent in whiskey drinks and Bee's Knees variations. For a smoked rosemary syrup, briefly torch a sprig of fresh rosemary until it begins to smoke, then add it to the sugar-water mixture before heating — the smoke binds to the syrup and creates a campfire-like herbal character.
