Rose Oil: Four Tonnes of Petals for a Single Kilo
Why the most famous flower in perfumery does not deserve its reputation as a grandmother's scent.
3 min read
No flower is so closely linked to perfume as the rose, and none is so underestimated. Many people have categorised "rose" as old-fashioned because they once smelled a heavy, soapy version of it. In reality, rose oil is one of the most complex and expensive natural ingredients in existence, capable of being anything from green and citrusy to jammy and wine-like. The figure that explains the price is easily told.
The calculation behind the price
For a single kilogramme of rose oil, depending on the variety and the year, around three to five tonnes of petals are required. They are picked by hand, in the few hours between dawn and sunrise, because the oil content drops rapidly thereafter. The season lasts for just three to four weeks a year. Anyone who does the maths will understand why genuine rose oil is among the most expensive liquids in the world.
Two varieties, two characters
- Rosa damascena, primarily from Bulgaria and Turkey: rich, honey-like, slightly wine-like. The classic "rose scent".
- Rosa centifolia, traditionally from Grasse: lighter, honey-sweet, with a green, almost fresh facet.
Distillation or extraction
Steam distillation yields rose oil, which appears cooler and clearer. Solvent extraction yields rose absolute, which is darker, denser, and closer to the fresh blossom. Both smell distinctly different, yet both are simply called "rose" in marketing copy.
Why rose oil does not smell like a grandmother
The old-fashioned impression usually stems from a specific era of soap perfumery, not from the raw material itself. Modern compositions contrast rose with pepper, leather, wood, or earth, bringing out its darker side. Anyone who has smelled such a rose quickly revises their judgement.
In brief
How many roses are needed for a kilo of oil?
Around three to five tonnes of petals, picked by hand in the hours before sunrise.
What is the difference between rose oil and rose absolute?
Oil is distilled and appears cooler and clearer. Absolute is extracted and is closer to the fresh blossom.
The upshot
Rose is not a note for beginners, and certainly not an old-fashioned one. It is the most versatile floral raw material known to perfumery, and depending on its surroundings, it can be fresh, dark, spicy, or wine-like. You can see where it plays a part in our range in the floral family, often combined with spicy notes, as in Scent No. 82 · Tropea or Scent No. 139 · Sestri Levante.
