Spearmint syrup is a cool, emerald-toned infusion made by simmering fresh spearmint leaves with sugar and water until it clarifies into a crisp, aromatic sweetener. Thanks to the high concentration of carvone—the compound responsible for its signature sweetness—and the absence of heavy menthol, it delivers bright, mellow, and garden-sweet notes—often stabilized with a touch of citric acid to maintain its clarity—making iced juleps, green teas, and sparkling lemonades taste cleaner, more uplifting, and more "meadow-fresh" than regular simple syrup.
