Ah, amber. It’s one of the most essential notes in perfumery, yet it’s totally imaginary – a fantasy note. Amber is named after the semi-precious natural amber, or fossilized tree sap, because they share the same rich honey-molasses hue.

There’s something about the feeling tone of amber: its warmth and richness, that makes many of us go all weak in the knees and grabby-hands. Ancient peoples revered the fossilized sap as a precious gem for its rich luster – and occasionally went baroquely insane with it, as seen above in the reconstruction of the 18th Century Amber Room (yes, constructed of real amber!) at the Catherine Palace of Tsarskoye Selo near Saint Petersburg.

But there is no amber in perfume “amber.”

Instead, amber is usually constructed around deliciously soft balsamic notes: rum-like and boozy sweet vanilla, leathery labdanum, and occasionally another resin, such as the creamy soft benzoin. The overall effect is rich and comforting, and the foundation of most oriental perfumes and some rich florals to help “fix” the more volatile flower notes.

Amber has many variations. I’m beginning with the accord in Mandy Aftel’s book, Essence & Alchemy. Her ratio:

• Benzoin absolute 20
• Labdanum absolute 5
• Vanilla absolute 1

How does it smell? Rich, dark, and sticky sweet – mouth-watering like a piece of dark toffee or caramel, yet not quite edible due to the faint leathery note in the labdanum. It’s used as a component of the perfume Alchemy in the same book, and I look forward to trying it in other compositions (and variations) too.
