Discover the Secrets Behind Vietnam’s Cassia Cinnamon

Cassia Cinnamon often hides in plain sight, taken for granted, yet it’s the superstar seasoning in your favorite dish. Surprisingly, not all cinnamon is created equal. In fact, the distinct aroma and flavor of cassia cinnamon set it apart from its sibling, Ceylon. But let’s dive deeper into what makes Vietnamese cassia cinnamon so special, shall we?

What Makes Cassia Cinnamon Unique?

Honestly, I won’t pretend I knew all this when I started. Cassia cinnamon, also known as “cay vang xanh” or “green gold tree,” is not just a spice; it’s a part of our cultural identity in Xuan Ai Commune. With over 6,000 hectares of cinnamon forest, of which 2,000 hectares are certified organic, our region has perfected the art of cultivating this aromatic wonder. Our cool mountain climate, perched between 200 to 1,000 meters altitude, coupled with rich soil, makes it the perfect home for cassia cinnamon to thrive.

Quick Facts

How Do We Cultivate Cassia Cinnamon? Step by Step

The lifecycle of cassia cinnamon trees is a patient one. Years 1 through 5 are all about laying the groundwork; we plant and nurture. Come years 3 to 5, we harvest the leaves for essential oils. And by years 8 to 10, the bark is finally ready for its first harvest. The peak quality hits between years 15 to 25, where the bark boasts a rich oil content of 3-5%. Harvest involves peeling the bark with a curved knife and sun-drying it for 3 to 7 days on bamboo racks. Every part of the tree finds a purpose: trunk bark becomes sticks, branch bark is split, and scraps are powdered. Even the leaves yield essential oils.

Cassia vs Ceylon: What’s the Difference?

In a market flooded with choices, understanding distinctions is crucial. Cassia cinnamon is known for its robust, spicier flavor, while Ceylon offers a sweeter, more delicate taste. The higher oil content in cassia contributes to its potent aroma. In contrast, Ceylon, or “true cinnamon”, offers a milder profile. Both have their places in the culinary world, but for a kick in your dish, cassia is your go-to. Curious to experience it firsthand? Check out our Vietnamese cinnamon.

6,000 Hectares of Tradition: A Brief History

Long before the world craved its zesty spice, cassia cinnamon was cherished by the Dao ethnic people, the first planters of Xuan Ai Commune. Known locally as “cay hanh phuc” or “happiness tree,” these trees were not just economic assets but held a deeper cultural significance. We’ve maintained this tradition, ensuring our farmers receive fair prices by selling directly, without middlemen. You can learn more about our story here.

Practical Takeaways for Cassia Enthusiasts

If cassia cinnamon has piqued your interest, here’s what to remember: it thrives in cool, mountainous regions like ours, which lend it its unique kick. The peak seasons of autumn (August-September) yield a higher oil content, ideal for those who crave intensity. For a gentler touch, spring (February-March) harvested bark will be your best bet. Next time you’re seasoning your dish, consider the journey this spice made—from tree to table, it’s a testament to time-honored practices.
