We bottle the weather

Isobar is a perfume house in Bergen, often called the rainiest city in Europe. We chase weather, capture the air it leaves behind, and recompose it into fragrance.

Five weathers so far. Synoptic Nº1, out now.

Forecast discussion · issued by the house

Every scent you remember is tied to a sky. The first rain on hot stone. A warm wind that makes the mountains look close enough to touch. Fog that tastes faintly of iron.

Forecasters read the sky as numbers. Perfumers read it as memory. We do both — then we wait, sometimes for years, for the right weather to arrive.

/ˈpɛtrɪkɔː/ n. The smell of first rain on dry ground.

Nineteen dry days, then rain at dawn on warm granite. We had the pumps running within four minutes of the first drop. The scent lasted eleven.

Føhn

/føːn/ n. A warm, dry wind that falls down the lee side of mountains.

The føhn brings headaches, avalanches and impossibly clear views. That afternoon it smelled of hot stone and last summer's hay, lifted out of the barns by the wind.

Brume

/bʁym/ n. Sea mist; fog that rises from cold water.

Summer fog in Nazaré arrives like a wall from the sea. Visibility eighty metres. Everything tasted faintly of salt and iron, and the sun was a small white coin. — move to clear the fog

Grésil

/ɡʁe.zil/ n. Graupel; soft snow pellets that bounce when they land.

At minus fourteen the air smells of almost nothing — which made it the hardest weather we have ever tried to bottle. Three winters, two failed captures, one perfect morning.

Method

How to catch a weather

  1. 01 — Watch

    We wait for the sky

    Our weather desk runs ensemble forecasts every six hours, looking for rare events. Most never arrive. Some take three winters.

  2. 02 — Chase

    We go to it

    When a forecast hits, a team leaves within the hour with portable pumps and adsorbent tubes. The good part of a weather often lasts minutes.

  3. 03 — Read

    We take it apart

    Back in the lab, gas chromatography–mass spectrometry separates each capture into hundreds of molecules, peak by peak.

  4. 04 — Recompose

    We build it back

    The perfumer rebuilds the air from safe, stable materials — not a photograph of the weather, but the memory of standing in it.

    A forecaster
    and a perfumer

    “A forecast is a promise about the air. So is a perfume. We just make ours keep.”

    Ingrid Solvang, co-founder

    Isobar began in 2019 with a phone call. Théo Marchetti, a perfumer trained in Grasse, rang a coastal forecasting office to ask a strange question: when would it next rain on warm stone? Ingrid Solvang, eleven years into night shifts, answered.

    Today Ingrid runs the weather desk, deciding when to chase. Théo turns captures into formulas in a former boathouse on the Bergen waterfront, where it rains about two hundred days a year. Neither of them owns an umbrella.
