The note presents a vibrant, often sharp and zesty initial impression, immediately awakening the senses. It possesses an inherent brightness, sometimes with an underlying bitterness or a slightly green, almost astringent quality that distinguishes it from the sweet pulp of the fruit. Texturally, it can evoke a waxy sheen, an oily residue, or a crisp, almost crackling sensation. Depending on the fruit, it might lean towards the effervescent tartness of citrus, the subtle woody-green dryness of an apple skin, or the slightly more resinous, almost candied warmth of certain tropical peels. Its intensity is typically high upon application, offering an immediate burst that projects widely as a classic top note. It tends to dissipate or soften gracefully, often leaving behind a clean, airy transparency, though its tenacious underlying nuances can linger, informing the heart notes with a subtle lift. While primarily a top note, certain more complex or exotic peels can weave into the heart, contributing a sparkling longevity.
