The Rum Sour highlights how lemon interacts with rum’s molasses, vanilla, and tropical fruit notes. Light rums produce crisp versions while aged rums yield richer, rounder sours. Shaken hard, it pours slightly opaque with a tart, juicy finish. Its structure predates modern tiki, tracing back to early rum punches distilled into simpler sours.
