CINNAMON COMPARISON

Ceylon cinnamon vs cassia: how to tell the difference

Ceylon cinnamon and cassia come from different Cinnamomum species and form visibly different bark products. Ceylon cinnamon usually forms a light, fragile quill made from many thin layers of inner bark. Cassia generally forms a darker, thicker and harder curl of bark.

Key points

  • Ceylon cinnamon: Cinnamomum verum.
  • Native range of Cinnamomum verum: Sri Lanka.
  • Ceylon quill: multiple thin layers.
  • Cassia stick: usually one or a few thick, hard layers.
  • Ceylon cinnamon generally contains considerably less coumarin than common cassia varieties.
  • A precise coumarin value must not be stated without testing the relevant product lot.

The quickest visual difference

Ceylon cinnamon generally has thin, paper-like bark layers rolled together. Its cross-section resembles a tightly packed cigar with many delicate layers.

Cassia commonly forms one thick inward curl or a small number of hard layers. Ceylon quills are usually easier to break or crumble than thick cassia sticks.

Colour is useful but not decisive because crops, processing, age, lighting and storage affect appearance. Use typically, commonly and generally because natural products vary.

Botanical names matter

Ceylon cinnamon is Cinnamomum verum. Cinnamomum zeylanicum is an older synonym still seen in trade and literature.

Cassia is a commercial umbrella term rather than one single product. Chinese cassia is commonly referred to as Cinnamomum aromaticum; Cinnamomum cassia also appears widely in trade and literature.

Indonesian or Korintje cinnamon is Cinnamomum burmanni. Vietnamese or Saigon cinnamon is Cinnamomum loureiroi. Powder cannot reliably be identified by shape, so suitable testing may be required for commercial verification.

How flavour differs

Ceylon cinnamon is generally described as milder, sweeter and more delicate. Cassia varieties are usually stronger and more forceful.

Indonesian Korintje is commonly associated with the familiar warm cinnamon profile used in North American baking, while Saigon cinnamon is known for an especially intense aroma and flavour. Suitability depends on the food, market and buyer preference.

Coumarin: the careful explanation

Coumarin is a naturally occurring flavouring substance found in several plants. It is generally present at higher concentrations in cassia cinnamon than in Ceylon cinnamon.

Regulatory and scientific authorities advise moderation with high, repeated cassia intake, particularly for people consuming large quantities regularly. Ceylon cinnamon is commonly selected when lower coumarin exposure is a priority.

Coumarin content still varies naturally. CeyQuills must not state a fixed percentage or make a lot-specific safety claim unless the relevant lot has been tested.

This page is general food information, not medical advice. Anyone using cinnamon in concentrated preparations, supplements or large repeated quantities should consult an appropriately qualified healthcare professional.

Which should a buyer choose?

Choose Ceylon cinnamon when the buyer wantsChoose a cassia type when the buyer wants
Sri Lankan originA stronger cinnamon impact
A layered, delicate quillA harder, thicker stick
A lighter flavour profileA familiar baking or beverage profile
Whole-quill presentationA particular regional specification
Lower coumarin as a general species characteristicA market that specifically requests cassia

How to verify a product

  • Ask for the botanical species.
  • Ask for the country of origin.
  • Inspect the cross-section of whole sticks.
  • Ask whether the product is whole, cut, quillings or powder.
  • Request actual-lot images.
  • For powder or high-assurance procurement, request appropriate species-authentication testing.
