What Is Amber Grease and Where Does It Come From?

Ambergris, often referred to as “floating gold,” has captivated human imagination for centuries. It washes ashore on beaches around the world, hinting at its unique origins from the depths of the ocean. Its enigmatic quality and the allure surrounding its discovery have made it a highly sought-after commodity throughout history.

The Origin and Nature of Ambergris

Ambergris originates from the digestive system of the sperm whale (Physeter macrocephalus), a deep-diving marine mammal. While the exact process of its formation is not fully understood, scientists believe it is a byproduct of the whale’s diet, primarily consisting of cephalopods like squid and cuttlefish. The indigestible parts of these prey, such as sharp beaks, are thought to irritate the whale’s intestinal lining. In response, a waxy substance forms around these irritants to protect the whale’s internal organs.

This waxy mass, which can take years to grow, is eventually expelled naturally by the whale, either through regurgitation or passing through the digestive tract. Once in the ocean, freshly expelled ambergris is typically soft, dark, and possesses a strong, unpleasant fecal odor. However, as it floats on ocean currents, exposed to sunlight and saltwater for years or even decades, it undergoes a transformative aging process.

During this maturation, the ambergris hardens, becomes lighter in color, ranging from gray to white, and develops a unique, complex aroma. This aged substance is often described as having a sweet, earthy, musky scent with notes of tobacco, vanilla, and the ocean. Beachcombers or those traversing the open seas typically discover ambergris as waxy clumps floating on the surface or washed up along coastlines.

Historical and Modern Applications

Throughout history, ambergris has found diverse applications across various cultures. Ancient civilizations, such as the Egyptians, used it as incense, believing its sweet, earthy scent could purify the air. In medieval Europe, during the Black Death, people carried pomanders containing ambergris, hoping it would offer protection from the plague. It was also incorporated into traditional medicine and consumed as a food flavoring.

Historical accounts suggest its use as an aphrodisiac; King Charles II of England reportedly enjoyed it mixed with eggs, and Casanova added it to his chocolate mousse. However, its most significant and enduring application has been in high-end perfumery.

In perfumery, ambergris functions as a fixative, a substance that helps other volatile fragrance compounds last longer on the skin. It does not merely impart its own scent but rather enhances and stabilizes the entire fragrance composition. Ambergris has a unique ability to mellow and round out other perfume notes, adding depth and complexity while preventing them from evaporating too quickly. This property made it a valuable ingredient in luxury fragrances for centuries, contributing to the richness and longevity of perfumes.

Rarity and Economic Value

The value of ambergris stems directly from its rarity. Only a small percentage of sperm whales, estimated to be between 1% and 5%, are thought to produce this substance. Its formation within the whale and lengthy natural aging in the ocean contribute to its scarcity, making its collection an infrequent and unpredictable event.

This scarcity drives its high market price. The value per gram of high-quality ambergris can be substantial, with prices reaching up to $120,000 per kilogram for the finest specimens. The quality, age, and purity of the ambergris significantly influence its market price. Fresh, dark ambergris is considered less valuable than the aged, lighter-colored varieties, with pure white ambergris commanding the highest prices due to its refined scent profile.

Legal and Conservation Status

The legal status of ambergris is complex and varies significantly across different countries. Since it is naturally expelled by sperm whales and collected after washing ashore, its retrieval does not directly harm the animals. However, the trade of products derived from endangered species is subject to strict regulations globally.

International agreements, such as the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), play a role in governing its trade. CITES generally considers naturally occurring ambergris, found floating or on beaches, as a waste product, which can make its collection legal in some regions. Conversely, national laws, such as the U.S. Endangered Species Act, prohibit the trade of all whale products, including ambergris, regardless of how it was obtained. This disparity creates a patchwork of regulations worldwide. Due to these legal concerns, as well as its rarity and cost, the perfume industry has increasingly relied on the development and use of synthetic alternatives to replicate the unique fixative properties and scent profiles of natural ambergris.
