The note bursts forth with an immediate, dazzling effervescence, a truly invigorating sensation that is simultaneously crisp, juicy, and slightly tart. It's not merely 'lime'; it possesses a distinct luminosity, a sun-drenched quality that is brighter and less intensely acidic than a typical lemon, yet more nuanced and complex than a generic green lime. There's a delicate interplay of sharp, sparkling zest and a soft, green, almost floral undertone that speaks of the fruit's ripened rind and verdant flesh. Its texture in the air is light and airy, almost gaseous in its initial lift, projecting widely before gracefully receding. As a quintessential top note, its longevity is fleeting but impactful, designed to make a vibrant first impression, often drying down to a softer, almost powdery whisper of citrus, or harmonizing with mid-notes to lend a persistent freshness.
