True cinnamon has been grown commercially in Sri Lanka for centuries, and despite attempts to cultivate it elsewhere, the island still produces the vast majority of the world's genuine Ceylon cinnamon. That's not coincidence — it comes down to history, geography, and soil that are genuinely difficult to replicate.
Cinnamon was among the very first spices traded in the ancient world, carried out of Sri Lanka by Arab traders along routes that eventually reached Europe. Control of the Ceylon cinnamon trade was valuable enough that it helped motivate the great age of maritime exploration, and colonial powers — the Portuguese, the Dutch, and later the British — fought at length over monopoly rights to it. Long before Ceylon tea existed, cinnamon was Sri Lanka's signature export to the world.
The finest cinnamon comes from a specific stretch of Sri Lanka's south-west coast — running through Galle, Matara and Kalutara, and inland to Ratnapura. This belt sees temperatures of roughly 25–32°C year-round and annual rainfall of 1,750–3,500mm across two monsoon seasons, conditions the cinnamon tree has adapted to over centuries. The soil is a slightly acidic sandy loam, rich in iron and manganese — soft enough for young roots to establish quickly, but mineral-rich enough to feed the tree's essential oil development.
Climate and soil explain why cinnamon grows well here — but the thin, multi-layered quill that defines Ceylon cinnamon is the result of generations of hand-peeling technique passed down through families of "cinnamon peelers" (salli karayo), a skill that still can't be fully replicated by machine at scale. That craftsmanship, combined with the growing conditions, is what produces the delicate sweetness and low coumarin profile that set Ceylon cinnamon apart from cassia grown elsewhere.
This isn't just marketing language — Ceylon Cinnamon became the first Sri Lankan product to receive Geographical Indication (GI) certification from the European Union, legally protecting the name for cinnamon genuinely grown and processed in Sri Lanka. Today Sri Lanka accounts for roughly 90% of the world's pure cinnamon exports, with the USA and Mexico as the largest single markets, alongside strong demand across Latin America and Europe.
