The note bursts forth with an initial sensation that is intensely bright, sharply zesty, and refreshingly tart, yet distinct from the common lemon or lime. It possesses a sophisticated bitterness, reminiscent of a crisp, green rind and the slightly pithy interior of the fruit, rather than a sugary pulp. There's an invigorating, almost effervescent quality to its projection, a sparkling clarity that cleanses the olfactive palate. As a quintessential top note, its initial intensity is profound but relatively fleeting, designed to provide an immediate, uplifting introduction. It carries a subtle, almost metallic nuance, lending it a polished, refined edge. While primarily a top note, its greener, more aromatic facets can linger briefly into the heart, offering a sophisticated bridge to deeper notes, maintaining a buoyant freshness without becoming overly sweet or cloying. It is crisp, linear, and remarkably transparent, lacking the juiciness of orange or the floral undertones of bergamot.
