If you've always bought cinnamon from the usual supermarket shelf, it's very likely that you've never actually tasted cinnamon at all — not the genuine article, at any rate. The discussion about Ceylon cinnamon and cassia cinnamon isn't merely a minor argument among food enthusiasts. It centres on two different plants, two distinct safety records, and two very different experiences in the kitchen. One is sweet, delicate, and safe to consume every day. The other is the kind found in about 90% of the spice jars in grocery stores worldwide and is often labelled simply as "cinnamon" without indicating which type it is.
The guide shows you how to tell the difference by looking, smelling, and tasting; explains why coumarin levels matter for your health; and tells you how to make sure the cinnamon in your cupboard is the real thing.
Ceylon Cinnamon and Cassia Are Not the Same Spice
They are cousins in botanical terms, not twins. Ceylon cinnamon comes from Cinnamomum verum, a tree native to Sri Lanka (and grown commercially on a small scale nowhere else). Cassia, by contrast, refers to a number of closely related species—Cinnamomum cassia from China, Cinnamomum burmannii from Indonesia (it is often sold as Korintje), and Cinnamomum loureiroi from Vietnam, which is known as Saigon cinnamon.
Both are obtained from the inner bark of trees and have a scent similar to cinnamon. However, the similarities end there. Ceylon cinnamon has a mild, citrusy sweetness and is very low in heat, while cassia is stronger and spicier, almost peppery by comparison—this is why it is used in most mass-market baking and why so many people think that must be how cinnamon tastes.
Sri Lanka has been growing and exporting true cinnamon since at least the 15th century, and the Cinnamon Coast, which extends through Galle, Matara, and Ambalangoda, still provides most of the world's Ceylon cinnamon today. Cassia, on the other hand, is produced in much larger quantities in China, Indonesia, and Vietnam, which is the reason it is cheaper and easier to find.
The Coumarin Issue: Why It Actually Matters
This is the section that most buying guides omit, and it may well be the most important distinction between genuine cinnamon and ordinary cinnamon on your spice shelf.
Both types of cinnamon contain coumarin as a natural compound, but the amounts differ greatly. Ceylon cinnamon has only trace amounts—usually about 0.004% to 0.02% by weight. Cassia, on the other hand, can contain as much as 1% coumarin, a figure which seems small when you calculate it in relation to normal usage.
The European Food Safety Authority has set the tolerable daily intake of coumarin at 0.1 mg per kilogram of body weight; for an average adult this amounts to about 5 to 7 mg each day. A single teaspoon of cassia cinnamon can contain between 7 and 18 mg of coumarin, depending on the source—so one heaping teaspoon in your morning oatmeal could easily exceed the recommended daily limit. Ceylon cinnamon, however, provides only a fraction of a milligram at the same doses.
Cassia cinnamon supplements, since they are often taken regularly (a common way of managing blood sugar), can lead to liver stress, and so the people who take them in this way are the ones most at risk of ending up with a high intake over time. This is why nutritionists increasingly advise using Ceylon cinnamon rather than cassia cinnamon for anyone who uses cinnamon every day, not just occasionally when baking.
How to Identify Real Ceylon Cinnamon
The good thing is that you won't need a laboratory to tell them apart; it's quite quick once you know what to look for.
Observe the stick. Ceylon cinnamon quills consist of several thin layers of bark rolled together, so that in cross-section they look like a cigar—soft, papery layers packed loosely, almost like a scroll made from several sheets. Cassia sticks are generally a single thick piece of bark curled into a tube, with a hard, hollow centre and no layered structure.
Look at the colour. Ceylon cinnamon is light tan to medium brown and fairly uniform, while cassia is darker—ranging from reddish-brown to deep rust—and usually has a more rugged, textured bark surface.
Try breaking it. The quills from Ceylon are brittle and will crumble or snap between your fingers. Cassia bark is dense and woody and usually requires a knife or a grinder to go through it.
Take a small amount and smell it. Ceylon has a soft, slightly sweet, almost floral scent with a citrusy note. Cassia, on the other hand, has a sharper and hotter smell and taste, something similar to the flavour of cinnamon candy.
Here's a quick way to remember the difference: Ceylon cinnamon is delicate and layered, while cassia is thick and solid; if the cinnamon stick you have looks more like a single rolled-up scroll than a bundle of thin curls, you are almost certainly holding cassia.
Is the cinnamon in the supermarket cassia or Ceylon?
It is very likely to be cassia, provided that the label does not state "Ceylon cinnamon" or "true cinnamon". In the United States, food labelling regulations do not require manufacturers to distinguish between the various types of cinnamon—legally, both kinds can be marketed using just the word "cinnamon". That isn't exactly deceit, but it does put the onus on the customer to look more closely.
Because it is ground cinnamon, the situation is even more difficult: you no longer have any visual clues from the stick. Ground powdered cassia and ground powdered Ceylon look very similar when stored in a jar. The best option for ground cinnamon is to choose a supplier that states the species on the label, preferably one that also gives some information about the origin—such as Sri Lanka for Ceylon, or China, Indonesia, or Vietnam for the various common cassia types.
If a product is priced in a way that suggests it's a good deal and doesn't state either Ceylon, Sri Lanka, or Cinnamomum verum on the packaging, then it can be assumed to be cassia and it usually is.
How Ceylon Cinnamon Is Grown and Graded in Sri Lanka
Understanding how the product is made helps explain both price differences and quality gaps. In Sri Lanka, peeling cinnamon is a specialised skill generally passed down from one generation to the next in areas where cinnamon is grown, such as Kosgoda, Matara, and Kurunegala. The peelers collect young shoots, typically two or three years old, during the rainy season because the bark separates more easily from the wood. The outer bark is scraped off, and the thin inner bark is carefully loosened and then peeled off in long strips by hand—an ability that takes many years to acquire, as tearing the bark damages the piece.
The strips are then placed one inside another and rolled into the usual quill shape before drying slowly in the shade to retain both the colour and the volatile oils that give the flavour; if sun-drying is too rapid, the bark may crack, or the aroma may become dulled.
The grading of cinnamon in Sri Lanka is based on the diameter of the quill and on its quality, the names of the grades sounding almost ceremonial: Alba is the best and thinnest grade, then come the Continental grades from C5 down to C1, followed by the Mexican grades M5 and M4, and finally the Hamburg grades which are used for coarser export. The Alba grade and the higher C grades are generally kept for premium retail and speciality export markets, while the lower grades, along with quillings (broken pieces) and featherings, are used for bulk grinding and industrial purposes. If you look at the grades listed on Ceylon spice products, the grade reflects true quality, not just a marketing term.
Buying Tips to Avoid Mislabeled Cinnamon
A few habits will keep you from accidentally ending up with cassia when you wanted the real thing:
- It is better to buy quills in whole form than to buy them as pre-ground powder since it is much easier to check their authenticity by looking at them.
- Make sure that the label explicitly lists 'Cinnamomum verum', 'Ceylon cinnamon', or 'true cinnamon', not just 'cinnamon'.
- Look to see where the cinnamon comes from; genuine Ceylon cinnamon originates in Sri Lanka and is not produced in any other place in significant amounts.
- One should be suspicious of any price that is unusually low for cinnamon marked as Ceylon since genuine cinnamon is more expensive to produce due to the need for hand-peeling, and prices below the normal market level should serve as a warning sign.
- When you are obtaining supplies for a business or a restaurant, don't just believe the labels; ask the suppliers for their grading documentation instead.
You don't need to become an expert in spices all at once, and after you've touched a real Ceylon quill once or twice, you'll quickly be able to tell the difference between cassia.
Getting It Right Matters More Than It Seems
The difference between Ceylon cinnamon and cassia cinnamon isn't merely a matter of interest for people who are keen on spices; it has an effect on the way your food tastes, on the amount of coumarin that you're actually ingesting, and on whether you're paying for a premium product or simply getting cassia with Ceylon-related marketing applied to it. After you've tried genuine Ceylon cinnamon in a simple dish, such as a cup of tea or a portion of rice pudding, you find it difficult to forget the difference.

Frequently Asked Questions
Is Ceylon cinnamon healthier than cassia cinnamon?
Yes, for ordinary, day-to-day use—mainly because of the difference in coumarin content. Since Ceylon cinnamon has only trace amounts of coumarin, frequent use will still keep you well below the tolerable daily intake, whereas cassia can surprisingly exceed that limit rather quickly. Although both types provide similar antioxidant benefits when used in moderate quantities, Ceylon is the safer option for regular use.
Why is Ceylon cinnamon more expensive than cassia?
Ceylon cinnamon is entirely peeled and rolled by skilled workers by hand, a method that is slower and more labour-intensive than harvesting cassia. Because Sri Lanka produces much smaller quantities worldwide than the main cassia-producing areas, supply remains limited. The price you're paying reflects the craftsmanship and scarcity, not just branding.
How can I work out whether the cinnamon in question is of the Ceylon or cassia type?
Start by looking at the label—true Ceylon powder must indicate the species or its origin. If the label doesn't say, do a simple visual check:e Ceylon powder is usually lighter ta, while cassia powder is darker and more reddish-brown. If you still aren't sure, the most dependable approach is to buy the quills whole and grind them yourself.
Does Ceylon cinnamon taste different when used in cooking?
Certainly. It is softer, sweeter, and has a citrus-like note instead of the sharp bitterness of cassia. Because its flavour is milder and doesn't dominate the other ingredients, many bakers use a little more Ceylon cinnamon than a cassia recipe calls for.
Can I get Ceylon cinnamon in bulk for my business?
Certainly — we provide services to cafés, bakeries, and spice retailers for bulk and wholesale orders. If you'd like to send your requirements, you can do so via our wholesale inquiry page, and we'll reply with grading options and pricing based on the volume you need.
What is the correct way of storing Ceylon cinnamon sticks in order to keep them fresh?
Store the quills in a tight container, away from light and heat, and keep them in a cool pantry rather than above the stove. When stored correctly, whole quills can retain their aroma for as long as two to three years, whereas ground cinnamon begins to lose its potency within a few months.
Do you ship Ceylon cinnamon internationally?
We supply products to customers and businesses worldwide, keeping quality and grading standards consistent from harvesting through packaging. Should you have any particular questions regarding shipping or importing into your country, please get in touch with us via our contact page, and our team will be able to go over it with you.
What is the difference between cinnamon sticks and cinnamon quills?
It's all the same thing, just with different names — "quill" is the more accurate term in the spice trade and refers to the rolled cylindrical form. The key difference is the name and structure: true Ceylon quills are made of several thin, rolled, layered strips, whereas a single thick rolled piece is almost always cassia.
