The note bursts forth with an immediate, radiant luminosity, a dazzling flash of pure sunshine. It is intensely juicy and succulent, with a vibrant, sparkling effervescence that tickles the olfactory senses. There's an initial sharp, zesty tang from the peel, swiftly followed by a profound, honeyed sweetness that is rich but never cloying. Beneath the primary sweetness, one can discern subtle, clean citrus undertones and perhaps the faintest hint of warm, sun-baked earth from its Mediterranean origins. Its texture is smooth, almost oily in its natural expression, yet it feels simultaneously airy and uplifting. As a quintessential top note, its projection is expansive and immediate, a glorious fanfare that quickly but gracefully recedes. Its longevity is characteristic of a citrus, offering a brilliant initial flash, then softening into a delicate, lingering warmth in the heart of a composition, perhaps mingling with florals or woods.
