SILLAGE

sillage (n.) — the trail a perfume leaves behind a person who has left the room.

Grasse, 1954. One room: a perfumer's atelier with a shuttered window, a marble bench, copper stills, and a wall of thirty-six amber vials. You have four thousand francs and six commissions ahead of you. The sixth is worth the whole career.

The one idea

A perfume is not a recipe. It is a structure in time.

Every material has a volatility. Citruses and aldehydes flash off in ten minutes; florals and spices hold the afternoon; resins and animalics are still on the skin at midnight. So your formula is never judged as a list — it is judged as a shape that rises, turns and falls.

Your clients write about that shape, never about ingredients:

"I want the first ten minutes and very little after them. Something to open a window with. It should be gone by the time I reach the market, and I should not be able to smell it on my coat tomorrow."

You can use every material a client loves and still be refused, because the shape was wrong. That is the game.

How to play

Enter	turn the page — start, read the notice, take the commission, go to the organ
Click a vial	add one drop of that material to the formula
Click a −	take a drop back off
Tremper la mouillette	strike the blotter and start the twenty-four hours
R	open the stock ledger — le registre
A	open the still — l'alambic
Escape	interrupt the session

The round

1. A commission arrives on the bench: a client, a brief in their own words, the shape they want as three bands, a fee, and a budget for materials.
2. Compose at the organ. Six tiers, thirty-six vials, volatile at the top and heavy at the bottom. Every drop appears on a hand-written formula card, with the perfumer's own corrections struck through in red.
3. Strike the blotter. Twenty-four hours pass in about twenty seconds.
4. Watch the drydown. Your accord draws itself as a wet ink line down the page — time runs downward, so the first ten minutes get a third of the sheet — over the client's requested shape, printed in ghost ink beneath it. The families in your formula stack in colour under the line.
5. Take the verdict. A score for each phase, the client's reply written across the sheet, and a stamp: chef-d'œuvre, accepté, or refusé.
6. Between commissions. Buy stock at prices that move with the season, or distil and tincture your own from whatever the fields sent in.

What makes it hard

• Volatility. A formula's curve is the sum of its materials' curves, which is why changing a proportion changes the object, not just its strength.
• Interaction. Materials do not merely stack. Some fix others and hold them for hours; some smother a note entirely; some are lovely alone and sour in company. The card tells you when it happens, in the margin.
• Overdose. Past a material's ceiling it flattens everything around it.
• Scarcity. Francs and stock are finite. Ambergris and civet are not sold at any price in Grasse — distil them, or do without.

Reading the drydown page

• Time runs down. 1 min at the top, 24 h at the foot, on a log axis.
• Intensity runs right. The further right the line, the louder the accord.
• The hatched band is what the client asked for. Stay inside it.
• Tête / cœur / fond are ruled across the page: the first twenty minutes, the afternoon, and what is left at midnight.
• On the verdict page a red dashed leader points from where your accord actually stood back to the edge of the band it missed. That is the whole explanation of a refusal, drawn.

Worth seeing

• The organ from the composing station: six tiers of amber and green glass with hand-written apothecary labels, ordered by volatility, so the wall of vials is the drydown curve stood upright.
• The morning light through the shutters, with the dust turning in the beam.
• Le livre de magasin — the stock ledger, set as a French pharmacy printing of 1954, with lines that read épuisé — plus rien when you have run a material out.
• A refusal you deserved: the curve visibly outside the band, and the client telling you so in one sentence.
