How Sri Lankan Cinnamon Became the World's Most Prized Spice

The Bark That Launched a Thousand Ships

Somewhere in the lush, rain-soaked lowlands of southwestern Sri Lanka, a man is doing something his family has done for generations uncountable. He holds a slim branch of the cinnamon tree, scores its thin bark with a curved knife, and begins to peel. The bark separates in translucent sheets — almost tissue-thin — which he rolls by hand into tight quills, layering sheet upon delicate sheet. When dried, these quills will become what the spice world calls true cinnamon: Cinnamomum verum, the real thing, as opposed to the cassia bark that fills ninety percent of the world’s cinnamon jars without apology or disclosure.

The difference between Ceylon cinnamon and cassia is not subtle. It is the difference between a whisper and a shout. Cassia hits you with a blunt, sweet intensity — pleasant enough, but one-dimensional. Ceylon cinnamon unfolds. It starts warm and sweet, then reveals layers of citrus, clove, and an almost floral delicacy that makes you understand why ancient civilizations valued this bark above silver.

An Island Defined by a Tree

Sri Lanka’s relationship with cinnamon is so deep that the spice essentially shaped the island’s history. Arab traders brought Ceylon cinnamon to Egypt as early as 2000 BCE, where it was used in embalming rituals and religious ceremonies. The Romans prized it extravagantly — Emperor Nero reportedly burned a year’s supply of cinnamon at his wife Poppaea’s funeral as a gesture of remorse and excess.

For centuries, the source of this miraculous bark remained a closely guarded secret. Arab middlemen invented elaborate origin stories to protect their monopoly, just as they did with other eastern spices. But Sri Lanka’s cinnamon coast — the strip of coastline south of Colombo where wild cinnamon forests grew in abundance — was eventually discovered by the Portuguese in 1505.

What followed was three centuries of colonial domination driven almost entirely by cinnamon. The Portuguese controlled the trade first, then the Dutch seized it in the 1600s, and finally the British took over in 1796. Each colonial power understood the same thing: whoever controlled Sri Lanka’s cinnamon controlled one of the most profitable commodities in the world. The Dutch, in their characteristically methodical fashion, established the first cinnamon plantations, transitioning from wild harvest to systematic cultivation.

The Art of the Cinnamon Peeler

The craft of cinnamon peeling is one of the most underappreciated artisan skills in the food world. In Sri Lanka, peelers belong to the Salagama caste, whose traditional hereditary occupation is cinnamon processing. While caste-based labor restrictions have loosened considerably, the skill itself remains concentrated among families who have passed it down for generations.

The process begins with harvesting branches from cinnamon trees that are typically two to three years old — old enough to have developed aromatic bark, young enough that the bark peels cleanly. The outer bark is scraped away, and then the inner bark is carefully loosened using a brass rod rubbed along the branch. This step requires a precise touch: too much pressure damages the delicate inner bark, too little leaves it stuck to the wood.

The peeler then rolls strips of inner bark into quills, fitting smaller pieces inside larger ones to create the characteristic layered structure of Ceylon cinnamon sticks. A skilled peeler can process approximately thirty to forty kilograms of quills per day, and the quality of the curl, the uniformity of the layers, and the thinness of the bark all affect the grade — and therefore the price — of the final product.

There are grades of Ceylon cinnamon as specific as wine classifications: Alba, the finest, uses only the innermost bark and commands the highest price. Continental and Mexican grades are progressively less refined. The grading system rewards the peeler’s skill directly; better technique produces higher-grade quills, and the best peelers are quietly famous within the industry.

Chemistry: Why Ceylon Wins

The flavor difference between Ceylon cinnamon and cassia is not just qualitative — it is chemical. Ceylon cinnamon gets its delicate character from cinnamaldehyde (the compound responsible for the “cinnamon” flavor everyone recognizes) present at lower concentrations than in cassia, combined with eugenol (the clove-like compound), linalool (floral), and a suite of other volatile aromatics that cassia largely lacks.

But the most significant chemical difference involves coumarin, a naturally occurring compound that can cause liver damage in high doses. Cassia cinnamon contains coumarin at levels between 1 and 18 milligrams per gram. Ceylon cinnamon contains only trace amounts — roughly 0.004 milligrams per gram. This thousandfold difference has real health implications for people who consume cinnamon regularly, whether in supplements, daily tea, or frequent baking. Several European countries have established maximum coumarin limits in food products, regulations that effectively favor Ceylon cinnamon.

A Spice With a Future

Today, Sri Lanka produces approximately 90 percent of the world’s true cinnamon, much of it still grown in the same lowland coastal belt where wild cinnamon forests once captivated Portuguese explorers. The industry employs tens of thousands of people and remains a critical component of the national economy.

Yet Ceylon cinnamon faces challenges. Cassia’s lower price and more aggressive flavor have made it the global default — most consumers have never tasted true cinnamon and do not know to ask for it. Climate change threatens the consistent growing conditions that cinnamon requires. And a generational shift means fewer young Sri Lankans are learning the peeling craft, drawn instead to less physically demanding work.

Still, there are reasons for optimism. The global appetite for premium, single-origin ingredients continues to grow. Health-conscious consumers increasingly seek Ceylon cinnamon for its low coumarin content. And the Sri Lankan government has invested in geographic indication protections to ensure that “Ceylon cinnamon” retains its meaning as a mark of origin and quality.

The next time you reach for the cinnamon in your pantry, pause and check the label. If it says simply “cinnamon,” it is almost certainly cassia. Seek out the real thing — the delicate, layered quill from Sri Lanka — and you will understand immediately why people sailed across oceans and fought wars over the bark of an unassuming tropical tree.
