The Story
Why it exists.
The beginning
Track 01 opens Aerse's catalog the way an album's first song does: setting a register before the listener knows what they're hearing. As a new Korean fragrance house, the brand treats each release as a verse in an ongoing composition, a numbered sequence rather than a mythology. Track 01 is the threshold, the entry point, the opening measure. Perfumer Maxime Exler built it around a tension that runs through the whole house: cool and warm held in the same hand. The name doesn't reach for geography or narrative. It numbers. Verse one. What sits in the bottle is a study in restraint, a fragrance that asks the wearer to lean in rather than be approached. It's crisp at the surface and warmed underneath, and that dual temperature is what the rest of the catalog keeps circling back to.
What makes Track 01 structurally interesting is the absence of traditional citrus up top. Instead of bergamot or lemon doing the bright work, Exler reaches for birch wood, ginger, and mint, a trio that feels crisp and energetic without becoming sharp. The birch gives the opening a faintly smoky, paper-like dryness. Ginger brings heat. Mint cools it back down. It's a three-note chord that behaves like an accord, each element leaning into the others rather than standing alone, and the effect is immediate without ever feeling loud.
The evolution
The first fifteen minutes belong to the top trio, and they move quickly. Birch and mint fade first, leaving ginger's warmth to thread into the saffron. That transition is where Track 01 finds its identity: the saffron doesn't sit flat. It wavers between medicinal and plush, pulled upward by jasmine, pulled downward by cedarwood's dry grain. There's a flickering quality to the midphase, a kind of breath between heat and haze that keeps the composition from settling into any single mood. Then the base registers come forward. Labdanum arrives with a low amber sweetness that reads more incense than syrup, dense and almost ecclesiastical. Myrrh adds a cool resinous edge, the kind that smells like cold stone and candle smoke, and vetiver grounds everything with that green-earth bitterness that keeps amber compositions honest.
Cultural impact
Track 01 manages to feel like a quiet statement in a category crowded with louder options. By leading with birch, ginger, and mint instead of the usual citrus sparkle, the fragrance offers a colder, more aromatic opening that rewards the wearer who leans in. The heart of saffron and cedar continues that thread, building a woody-amber core that avoids the sweetness many releases default to. Labdanum, myrrh, and vetiver close the composition with a resinous, earthy register that feels meditative rather than heavy.
