Profile

Cinnamomum cassia, called Chinese cassia, cassia cinnamon, or Chinese cinnamon, is an evergreen tree originating in southern China and widely cultivated there and elsewhere in South and Southeast Asia. It is one of several species of Cinnamomum used primarily for its aromatic bark, which is used as a spice. The buds are also used as a spice, especially in India, and were used by the ancient Romans.

Cassia is the cinnamon most of the world actually eats. Harvested from the thick bark of Cinnamomum cassia trees grown across southern China, northern Vietnam and the Indonesian island of Sumatra, it carries a cinnamaldehyde load of 80% or more, giving that familiar candy-shop kick behind American cinnamon rolls, Chinese five-spice and Mexican pan dulce. The bark rolls into hard, single-curl quills the colour of dried blood, denser and woodier than its Ceylon cousin. It also carries coumarin, a compound flagged by European food authorities, which is why Saigon cassia is both loved for its intensity and treated with care in daily baking.

Process

01Apr–May

Wet-season felling

Branches cut when the sap is rising — the bark lifts cleanly from the wood. Only trees 10+ years old yield the deep-red inner bark.

02Same day

Bark stripping

Workers score and peel long ribbons of inner bark with curved knives, working in the shade to slow oxidation.

0324–48 h

Fermentation

Ribbons stacked under damp cloth. Enzymes develop the brick-red color and deepen the sweet-woody aroma.

043–5 days

Sun-curling

Laid on bamboo racks. As moisture leaves, the bark curls into thick single-quill scrolls — the cassia signature.

05Grading

Sort by thickness

Tubes graded by wall thickness and oil content. Vietnamese Saigon tops the range at 4–5% cinnamaldehyde by mass.

06Your jar

Sticks or ground

Whole sticks hold aroma 3+ years. Ground cassia fades in 6 months — grate on a microplane as needed.

Story

Frequent questions

They're different species. Cassia (Cinnamomum cassia/loureiroi/burmannii) is bold, hot, candy-red — driven by 80–90% cinnamaldehyde and backed by 0.4–0.8% coumarin. Ceylon (Cinnamomum verum) is delicate, floral, citrusy — only 50–65% cinnamaldehyde and virtually no coumarin. If your supermarket cinnamon is dark, thick-walled, and rolled into a single tube, it's cassia. If it's paler, thinner, and made of many soft layers, it's Ceylon.
