The note unfolds with an immediate, bracing burst of brilliant, effervescent citrus, sharper and more complex than a lemon, yet less overtly sweet than a mandarin. It presents a sophisticated tartness, interwoven with a distinctive green, almost herbal undertone, and a subtle, elusive floral whisper that elevates it beyond mere fruit. There's a delicate bitterness, akin to grapefruit pith but more refined, providing a crucial depth. Its texture is crisp and airy, almost sparkling, conveying a sense of pristine cleanliness. As a quintessential top note, its projection is initially vibrant and far-reaching, a luminous halo, but it gradually recedes, leaving a clean, refreshing impression rather than a heavy trail. Its longevity is characteristic of a citrus, fleeting but impactful, intended to introduce a composition with clarity and verve.
