If you’ve ever looked closely at a bag of real Ceylon cinnamon, you may have noticed a small code printed on the label — something like “C5” or “C4,” sometimes written together as “C5/C4.” That code isn’t a batch number or a shipping stamp. It’s part of a real, long-established cinnamon grading system, and it tells you something concrete about the quality of what’s inside the bag. Here’s what it actually means, and why it matters for the cinnamon you cook with.
Cinnamon grading is about the quill, not the flavor claim
True Ceylon cinnamon (Cinnamomum zeylanicum, sometimes written Cinnamomum verum) is harvested by peeling thin layers of inner bark from the cinnamon tree. Those layers are dried and rolled by hand into the thin, papery, multi-layered sticks known as quills — the ones that look almost like a rolled cigar, very different from the single thick curl of a cassia cinnamon stick.
Because the bark is hand-peeled and hand-rolled, no two batches come out identical. Some quills roll thinner and more uniform; others come out thicker or less even. The Sri Lankan cinnamon trade has used a grading system for generations to sort finished quills by exactly that: diameter and uniformity. The thinner and more consistent the quill, the higher the grade — and generally, the more of the finest, innermost bark went into it.
What the grades actually mean
The full grading scale runs from the most prized grade down to lower grades used mostly for grinding into powder or for commercial/industrial use. The broad groups you’ll see referenced in the trade are Alba, Continental (C), Mexican (M), and Hamburg (H), each split into sub-grades by quill diameter:
- Alba — the thinnest, most delicate quills, and the most prized grade. Reserved almost entirely for whole-stick sale and specialty use.
- C5 and C5 Special — Continental-grade quills, still quite thin, sold as a premium whole-stick product.
- C4 — a slightly thicker Continental grade than C5, still genuine quill-rolled bark, not scrap.
- Lower grades and by-products — thicker M- and H-grade quills, plus quillings (broken pieces), featherings (inner bark of twigs), and chips, which are typically sold for powder or industrial extraction rather than as whole sticks.
A note on precision: you’ll find slightly different exact millimeter cutoffs for each grade depending on the source — exporters, the Sri Lanka Export Development Board, and individual retailers don’t all publish identical numbers, and we’d rather tell you that honestly than hand you a precise-looking figure we can’t fully stand behind. What’s consistent across every source is the ranking itself: Alba is thinner and more prized than C5, C5 is thinner and more prized than C4, and both C5 and C4 are genuine, good-quality whole-quill grades — a meaningfully different product from cassia cinnamon or ground cinnamon of unknown origin.
Why our cinnamon sticks are graded C5/C4
Our Ceylon Cinnamon Sticks (Quills) carry the C5/C4 grade mark on the package because that’s an honest reflection of what’s inside: genuine hand-rolled Ceylon cinnamon quills, not the broken bits, chips, or powder-grade material that gets sold at a lower price under a vaguer label. We’d rather print the real grade than an inflated one.
Does the grade affect flavor?
Within genuine Ceylon cinnamon, the grade mostly reflects the physical form and uniformity of the quill rather than a dramatic flavor difference — a C5 and a C4 quill come from the same tree, the same region, and the same inner-bark harvesting process. The much bigger flavor and quality gap is the one between any grade of real Ceylon cinnamon and cassia cinnamon, which is a different species entirely, with a stronger, more one-note heat and a noticeably higher coumarin content. We cover that comparison in detail in Ceylon Cinnamon vs. Cassia: Why “Real” Cinnamon Matters.

Frequently asked questions
What does the C5/C4 code on my cinnamon package mean?
It’s a Sri Lankan cinnamon trade grading code describing the quill’s diameter and quality tier. C5 and C4 are both genuine Continental-grade whole-quill cinnamon, with C5 slightly thinner than C4. It’s a mark of real, hand-rolled quality, not a defect code.
Is C5 better than C4?
C5 is a thinner, slightly more refined grade than C4, but both are legitimate, good-quality whole cinnamon quills — not scraps or powder-grade material. The flavor difference between the two is minor compared to the difference between genuine Ceylon cinnamon and cassia.
Is Alba cinnamon better than C5?
Alba is the thinnest and most prized grade, generally considered the top of the Ceylon cinnamon scale, above C5 and C5 Special.
Does a higher grade mean more health benefits?
No — grade is about physical form (quill thickness and uniformity), not nutrient or coumarin content. What matters most for safety and quality is that it’s genuine Ceylon cinnamon (Cinnamomum zeylanicum) rather than cassia, regardless of which Ceylon grade you’re using.
