The note of Fucus, specifically referring to Fucus vesiculosus or bladderwrack, unfurls as a deeply complex and evocative marine accord. It is not merely salty, but rather embodies the full spectrum of the ocean's edge: a rich, briny salinity that is both mineralic and slightly iodinic, reminiscent of sea-kissed stones and sun-baked tidal pools. There's a verdant, almost mossy greenness that hints at its algal nature, sometimes with a damp, earthy undertone as if you've just overturned a rock on the shoreline. The texture is perceived as wet, cool, and somewhat rough, yet paradoxically clean. Its intensity can range from a subtle, ethereal whisper of sea breeze to a powerful, almost animalic surge of low tide. It typically emerges as a robust heart note, often extending into the base, providing exceptional longevity and a unique, diffusive projection that carries the authentic scent of the wild coast. It evolves from a sharper, more immediate salinity to a warmer, more integrated marine depth over time, softening its initial raw edge into a serene, meditative oceanic embrace.
