Walk into any grocery store in the United States and pick up a jar of cinnamon. The label almost certainly says "cinnamon" — species unspecified, origin unlisted. What's inside is almost certainly not Ceylon (Cinnamomum verum), the variety historically known as true cinnamon and the only one indigenous to Sri Lanka.
The four main types of cinnamon sold commercially — Ceylon, Chinese cassia, Saigon (Vietnamese), and Korintje (Indonesian) — come from different species of the Cinnamomum genus. They differ in flavor intensity, bark structure, chemical composition, coumarin content, and the applications they suit. Understanding the difference matters whether you're using cinnamon daily for health reasons, selecting the right variety for a specific recipe, or simply trying to know what's actually in the jar.
This guide covers all four types in full, with a comparison table, coumarin data, and a plain-language guide to which type to use for what.
The Botanical Framework: One Species vs. Three
Before covering each type, the most important structural point: "cinnamon" is not one thing botanically.
Ceylon cinnamon (Cinnamomum verum, also written C. zeylanicum) is a single species — grown primarily in Sri Lanka, with smaller production in Madagascar and the Seychelles. Its botanical name, verum, means "true" in Latin — a name assigned by early European botanists.
Cassia cinnamon is a commonly used label for three separate species that share similar appearances and chemical profiles but are botanically distinct:
- Chinese cassia — Cinnamomum cassia (also C. aromaticum) — the original, from southern China
- Saigon cinnamon — Cinnamomum loureiroi — from Vietnam
- Korintje cinnamon — Cinnamomum burmannii — from Indonesia
This two-tier structure — one true species, three cassia varieties — is the clearest mental model for understanding why these cinnamons behave and taste differently. All three cassia types are harder, darker, and more coumarin-heavy than Ceylon. But they differ meaningfully from each other too — particularly in coumarin content and flavor intensity.
Ceylon Cinnamon (Cinnamomum verum)
Origin: Sri Lanka primarily (80%+ of global supply), with minor production in Madagascar, Seychelles, and southern India
Bark appearance: Light golden-tan. Multiple thin, papery inner bark layers — typically 7–10 — hand-rolled into quills. The rolled structure resembles a tightly wrapped cigar or a scroll of fine paper. Pencil-thin diameter, usually under 6mm for Alba grade.
Texture: Fragile. Ceylon quills crumble between fingers. The bark is brittle because each layer is genuinely thin inner bark, not thick outer bark. This fragility is a quality indicator, not a defect.
Flavor profile: Delicate, naturally sweet, with distinct floral and faintly citrusy undertones. The flavor comes from a balanced volatile oil composition: approximately 50–63% cinnamaldehyde (warm spice), plus meaningful proportions of eugenol (clove-like depth) and linalool (floral, citrusy lift). This three-compound balance produces a layered flavor that cassia — cinnamaldehyde-dominant — cannot replicate.
Coumarin content: Approximately 0.004% — the lowest of all commercial cinnamon types. This is roughly 250–400 times less than typical cassia varieties.
Where it grows: Sri Lanka's cinnamon cultivation is concentrated in the southern wet zone around Matara, Galle, and Negombo. The humid tropical climate, red laterite soil, and generations of cultivating knowledge produce a bark profile specific to this geography. Our Alba-grade Ceylon cinnamon quills are sourced directly from Sri Lanka — the only country whose cinnamon carries the "Ceylon" designation by geographic origin.
What it's best for:
- Daily tea and coffee additions (low coumarin makes it safe at regular quantities)
- Delicate baked goods where cinnamon should accent rather than dominate: custards, panna cotta, shortbread, rice pudding, apple tarts
- Traditional Mexican and Sri Lankan cooking — both cuisines historically built on Ceylon, not cassia
- Cinnamon supplements and high-dose culinary use
Chinese Cassia (Cinnamomum cassia)
Origin: Southern China — Guangxi and Guangdong provinces primarily
Bark appearance: Dark reddish-brown. Single-scroll structure — the bark curls in one layer from both edges toward the center, creating a thick, hollow tube. Hard and dense. Significantly thicker than Ceylon, typically 8–15mm diameter.
Texture: Hard and woody. Requires a grinder to break down; not crumbleable by hand.
Flavor profile: Bold, spicy, and assertive. The high cinnamaldehyde concentration (approximately 69% of volatile oil content) produces the sharp, pungent "cinnamon heat" most Americans associate with the spice. Less sweet than Ceylon, with a slightly bitter finish at longer cooking durations. Think of cinnamon chewing gum — that's Chinese cassia flavor.
Coumarin content: Approximately 1–2% — significantly higher than Ceylon, somewhat lower than Saigon.
What it's best for:
- Strong-flavored baking where cinnamon is the headline ingredient: cinnamon rolls, snickerdoodles, speculoos, cinnamon bread
- Short cooking applications where the bitterness doesn't have time to develop
- Recipes that specifically want "classic American cinnamon" flavor
What to know: Most generic grocery store cinnamon labeled only "cinnamon" is either Chinese cassia or Korintje. Read our cassia vs. true cinnamon deep-dive for the full picture on labeling and identification.
Saigon Cinnamon (Cinnamomum loureiroi)
Origin: Vietnam — particularly Yên Bái and Quảng Ngãi provinces
Bark appearance: The darkest of the four types. Deep reddish-brown, sometimes with orange undertones. Thick, single-scroll bark, densest of all commercial cinnamon varieties.
Texture: Rock hard. More resistant to breaking than Chinese cassia. Significant force required to break a stick.
Flavor profile: The most intense of all four types. Saigon cinnamon contains the highest essential oil content of any commercial cinnamon variety — approximately 3–5% cinnamaldehyde versus cassia's 1–2% (per the Journal of Agricultural and Food Chemistry). The result is an almost peppery, fiery heat that is significantly more aggressive than Chinese cassia. Sweetness is present but overwhelmed by the spice intensity. The warmth lingers.
Coumarin content: The highest of all four types — approximately 4–8%, and in some samples measuring higher. The University of Mississippi study quantifying coumarin levels across cinnamon species confirmed Saigon consistently at the top of the coumarin range. For daily use, the EFSA's Tolerable Daily Intake of 0.1 mg coumarin per kg bodyweight can be approached with a small amount of Saigon cinnamon.
What it's best for:
- Bold, high-impact recipes where cinnamon needs to cut through other strong flavors: holiday gingerbread, heavily spiced mulled wine, dark chocolate desserts
- Pho broth — the traditional Vietnamese application (used in small amounts with star anise and cloves)
- Cinnamon rolls where maximum cinnamon punch is the goal — this is what commercial chains (including Cinnabon) use for flavor intensity
What to watch: Saigon is the most commercially marketed "premium" cinnamon in the US (often sold at price premiums over generic cassia). However, its high coumarin content means it is the least suitable for daily use or supplementation. If you see "Vietnamese cinnamon" or "Saigon cinnamon" marketed as a health supplement, the coumarin argument runs against that framing.
Is Saigon cinnamon the same as Ceylon? No. They are completely different botanical species from different countries with different flavor profiles, bark structures, and coumarin levels. Saigon (C. loureiroi) is significantly more potent and significantly higher in coumarin than Ceylon (C. verum).
Korintje Cinnamon (Cinnamomum burmannii)
Origin: Indonesia — primarily Sumatra and Sulawesi
Bark appearance: Medium brown. Single-scroll structure, thicker than Ceylon but not as dense as Chinese cassia or Saigon. The color is typically warmer and less red than Chinese cassia.
Texture: Hard but slightly less dense than Saigon. Requires a grinder.
Flavor profile: The most moderate of the cassia varieties. Smooth, warm, and familiar — described by food writers as "classic American baking cinnamon." Less aggressive than Chinese cassia, far less intense than Saigon. If Chinese cassia is a strong espresso, Korintje is a medium roast drip coffee — broadly accessible, crowd-pleasing, not challenging.
Coumarin content: Approximately 2–6%, placing it above Chinese cassia (1–2%) and below Saigon (4–8%). Still considerably higher than Ceylon (0.004%).
What it's best for:
- Everyday household cooking where cinnamon plays a supporting role: oatmeal, pancakes, French toast, pumpkin spice blends
- Spice blends (pumpkin pie spice, apple pie spice, chai spice mix) where cinnamon needs to blend in
- Baked goods where you want accessible cinnamon warmth without overwhelming heat
Important context: If you've bought a generic $3 jar of ground cinnamon at a US grocery store, it's almost certainly Korintje — not Chinese cassia and almost certainly not Ceylon. Korintje is the cheapest to produce at volume and the most commonly imported variety for US retail. The smooth, familiar flavor is why it's so widely used as the "default."

The Coumarin Reality — Why It Matters for Regular Users
Coumarin is a naturally occurring compound present in varying concentrations across cinnamon species. At high doses, it can cause liver stress — particularly in individuals with existing liver sensitivity. The EFSA's Tolerable Daily Intake of 0.1 mg coumarin per kg bodyweight is the established safe daily limit.
What this means in practice for a 150lb (68kg) adult:
| Type | Coumarin % | Safe daily amount (approx.) | Context |
|---|---|---|---|
| Ceylon | 0.004% | Several teaspoons — no practical concern | Daily use at any culinary amount is fine |
| Korintje | ~3% avg | ~½ tsp before approaching TDI | Occasional large amounts fine; daily supplement use requires care |
| Chinese Cassia | ~1.5% avg | ~1 tsp per day approaches TDI | Same caution |
| Saigon | ~6% avg | ~¼ tsp reaches TDI | Most caution required — least suitable for daily supplement use |
The numbers differ considerably by source and sample — the University of Mississippi study quantifying coumarin levels across cinnamon species provides the most rigorous published data. The key takeaway: the gap between Ceylon and all cassia types is substantial. The gap between different cassia types is also meaningful, and Saigon is consistently at the top.
For anyone using cinnamon as a daily supplement or in significant daily culinary amounts, these numbers are the argument for Ceylon. For occasional baking, none of this presents a practical concern at normal recipe quantities.

Which Type of Cinnamon Should You Use?
This is the decision most articles avoid making directly. Here's a clear guide:
Daily tea, coffee, or smoothies: Ceylon (C. verum). Every day at culinary amounts — no coumarin concern. Flavor is delicate enough not to overpower drinks.
Daily supplement or high-dose use: Ceylon only. The coumarin math is unambiguous at therapeutic amounts.
Delicate baked goods (custard, apple tart, shortbread, panna cotta, rice pudding): Ceylon. Its subtle sweetness complements without dominating. Most European and Middle Eastern recipes that call for cinnamon historically used Ceylon.
Traditional Mexican cooking (canela in atole, champurrado, Mexican hot chocolate): Ceylon. Mexico is the world's largest importer of Ceylon cinnamon — traditional canela is C. verum, and the flavor profile of these dishes was built around it. American substitutions with cassia or Saigon alter the intended taste significantly.
Everyday household cooking (oatmeal, pancakes, apple crisp, breakfast baking): Korintje works well — it's likely what you grew up tasting. Ceylon also works and is milder.
Bold cinnamon-forward baking (cinnamon rolls, snickerdoodles, gingerbread, spiced cider): Saigon or Chinese cassia. Their high cinnamaldehyde content provides the assertive heat these recipes are designed around.
Pho broth and Vietnamese cooking: Saigon (C. loureiroi) — this is the traditional variety, used with star anise, cloves, and black cardamom. The intensity is appropriate at the small amounts used in broth.
What does Cinnabon use? A Saigon/Korintje blend — the specific recipe is proprietary, but the flavor profile targets high-intensity cinnamon heat achievable only with high-cinnamaldehyde cassia varieties. It is not Ceylon.
How to Tell Which Type You Have
If you have whole cinnamon sticks, layer-count is the most reliable test — Ceylon shows 7–10 thin separable layers; all cassia types show 1–2 thick fused layers. For ground powder, label reading is the only reliable method: look for "Cinnamomum verum," "Ceylon cinnamon," or "Product of Sri Lanka."

Frequently Asked Questions
What are the four main types of cinnamon? Ceylon (Cinnamomum verum), Chinese cassia (C. cassia), Saigon/Vietnamese (C. loureiroi), and Korintje/Indonesian (C. burmannii). Ceylon is a distinct species; the other three are all classified as cassia-type cinnamons, sharing similar bark structures and higher coumarin content, but differing in flavor intensity and coumarin levels.
What is Saigon cinnamon and is it good for you? Saigon cinnamon (Cinnamomum loureiroi) is from Vietnam. It has the highest essential oil content and most intense flavor of all commercial cinnamon types — excellent for bold baking. However, it also contains the highest coumarin levels (approximately 4–8%), making it the least suitable for daily supplementation or high-dose regular use.
Is Saigon cinnamon the same as Ceylon cinnamon? No — completely different species from different countries. Saigon is from Vietnam (C. loureiroi), is dark and intensely spicy, and contains very high coumarin. Ceylon is from Sri Lanka (C. verum), is light and delicate, and contains negligible coumarin. They share the word "cinnamon" but differ in species, flavor, bark structure, and safety profile.
What is Korintje cinnamon? Korintje cinnamon (Cinnamomum burmannii) is Indonesian cinnamon — the most widely available commercial cinnamon in the United States. Most generic, unlabeled ground cinnamon in US grocery stores is Korintje. It has a smooth, familiar, moderate flavor and is higher in coumarin than Ceylon but slightly less than Saigon.
Which type of cinnamon is the healthiest? For regular and daily use, Ceylon (Cinnamomum verum) has the most favorable safety profile due to its dramatically lower coumarin content — approximately 0.004% versus 1–8% in cassia varieties. For occasional baking use at normal recipe amounts, coumarin levels across all types present no practical concern.
What cinnamon is best for baking cinnamon rolls? Saigon or Chinese cassia. Their high cinnamaldehyde content (up to 90% in Saigon) produces the assertive, heat-forward cinnamon punch that cinnamon rolls are designed around. Ceylon is too delicate for recipes where cinnamon is the primary flavor driver.
Does it matter which type of cinnamon you use? For occasional cooking — generally not significantly. For daily use at meaningful quantities, daily supplementation, tea habits, or high-dose culinary use — yes, the type matters. Ceylon's coumarin level is low enough to be a non-issue at any reasonable culinary amount. Cassia varieties require more consideration for daily heavy use.
The Transparent Answer
WeeSpice sells Ceylon cinnamon (Cinnamomum verum), so we have a clear interest in explaining why it matters. We've tried to give you the full, honest comparison — including where cassia types are the better choice (bold baking, pho, cinnamon rolls) — because the decision should be based on actual use, not brand positioning.
If you use cinnamon daily in tea, coffee, oatmeal, or supplementally, the coumarin differential makes Ceylon the more sensible choice. If you bake aggressively spiced cinnamon rolls on weekends, Saigon is what the recipe calls for. Those aren't competing facts — they're different use cases.
For daily use, our Alba-grade Ceylon cinnamon quills and Ceylon cinnamon powder are Cinnamomum verum, single-origin Sri Lanka, small-batch packed — with the species and origin stated clearly because that's information you should have.
