Ambergris

Ambergris is a rare natural material formed in the digestive system of sperm whales and weathered for years at sea. Once aged, it has a soft, sweet, earthy and marine scent with a skin-like warmth, and for centuries it was one of perfumery's most prized fixatives. Today it is used only in tiny amounts, mostly replaced by synthetic molecules.

What does Ambergris smell like?

Fresh ambergris is dark and smells strongly faecal and marine. After long exposure to sun, salt water and air it lightens in colour and develops a completely different character: sweet, earthy and slightly musky, with notes often compared to tobacco, damp wood, seaweed and warm skin. Its smell is quite unlike the amber accord, which is a sweet resinous blend, and more complex than ambroxan, the single molecule that captures its dry, woody-salty backbone.

Where Ambergris comes from

Only a small proportion of sperm whales produce ambergris, which is thought to form around indigestible squid beaks. Lumps are expelled into the sea and may float for years before washing up on beaches, most famously in New Zealand, Australia, the Atlantic coast of Europe and the Indian Ocean. For perfumery, pieces are ground and steeped in alcohol for months to make a tincture.

Ambergris in perfume history

Ambergris was valued across the Arab world, China and medieval Europe as perfume, incense, medicine and even a flavouring. Chinese sources called it dragon's spittle fragrance, and Charles II of England was reputed to eat it with eggs. The odourless compound ambrein was identified as its main component in 1946, and later work showed that its breakdown products, including ambroxide, create the characteristic smell.

Ambergris in modern perfumery

Mainstream perfumery relies almost entirely on synthetic ambergris materials such as Ambrox, Cetalox and ambrinol. Real ambergris tincture survives in a handful of luxury and artisan perfumes. Because sperm whales are protected, trading ambergris is illegal in some countries, including the United States, Australia and India, while others permit the sale of pieces found washed ashore.

How Ambergris wears and what it pairs with

As a base note ambergris is diffusive and extremely long lasting, adding radiance and a skin-like depth rather than a distinct smell of its own. It flatters florals, citrus and woods alike, especially rose, jasmine, bergamot, sandalwood, iris, musk and labdanum.
