Kerinci Cinnamon: Mountain Spice of Jambi and Its Uses
Kerinci cinnamon is a bark spice grown on the slopes of Mount Kerinci in Jambi province, Sumatra. The bark comes from the Korintje tree, Cinnamomum burmannii, and the valley below the volcano supplies the largest share of Indonesia’s cinnamon. The bark is peeled in strips, scraped, rolled and dried into hard, dark quills that smell sweet and woody. Cooks use it in savoury dishes, drinks and desserts, and it tastes quite different from the thin cinnamon most people buy in a jar. This page covers where the spice grows, how the bark is cut and dried, what it tastes like, and how to use and store it. For the wider province, start with the Jambi guide.
Kerinci cinnamon: the species, the name and its registered origin
The tree behind this spice is Cinnamomum burmannii. In the valley it is known as Korintje, and older trade names spell it Koerintji. It belongs to the cassia group of cinnamons rather than the Ceylon group, so its bark is thicker, darker and more assertive than the bark sold as true cinnamon in many countries. The name has been protected since 2016, when the spice received a geographical indication under the name Kayumanis Koerintji. That status ties the name to the Kerinci area and gives buyers a way to recognise the real product, but it does not by itself change what a farmer earns. That gap comes up again later on this page.
The highland valley and the volcano above it
Kerinci is a highland valley in western Jambi, ringed by mountains and dominated by Mount Kerinci. At 3,805 metres, the volcano is the highest in Indonesia and the highest peak on Sumatra, and its slopes hold farms, villages and forest. Ash from past eruptions has enriched the soil on the lower slopes, and the cool, damp air of the highlands suits a tree that prefers steady moisture to heat. The valley is one of the few places where cinnamon of this type is grown in large volumes, which is why the name of the valley and the name of the spice have become so closely linked.
Walk through the lower villages and the pattern is clear. Cinnamon grows beside coffee, vegetables and fruit trees, and many families keep it as a long-term store of value rather than a crop they cut every year. A mature tree can stand for decades, so it works like a savings reserve: it is cut when money is needed and left alone when it is not. The villages at the foot of the volcano, such as Kersik Tua, show this mixed-garden pattern clearly, with cinnamon trees rising between house plots and forest edges.
The cinnamon tree and the long wait before harvest
The tree is evergreen and can grow tall in the forest, often more than ten metres. It is a slow crop. Seedlings need several years before they are large enough for their bark to be taken, and a tree grown for its thickest bark needs far longer than that. The exact timing depends on the site, the tree and the grower, so anyone planting cinnamon should expect a long wait before a meaningful return.
That delay shapes behaviour across the whole valley. A family that plants cinnamon today will see little income for years, which is why many growers combine it with faster crops such as coffee and why new planting has at times pushed onto land that was not farmed before. Understanding the time lag explains a great deal about the choices people make on the mountain’s lower slopes.
How the bark is cut, dried and rolled into quills
Choosing and felling trees
Harvesters choose trees that have reached a suitable size and carry bark thick enough to be worth the effort. The common practice is to fell the selected tree, then cut the trunk and main branches into lengths that can be worked by hand. Felling is the method that does the most harm to the forest, and it is the approach the forest section below returns to.
Stripping, scraping and drying
The bark is peeled in long strips while it is still moist, because it lifts most easily soon after cutting. Each strip is scraped to remove the thin outer skin and the rough layer beneath it. The strips are then rolled, with each one tucked inside the next, and laid out to dry in open air. As the bark dries it curls into the familiar quill, which hardens, darkens and becomes fragrant. A well-dried quill breaks cleanly and smells sweet even before it is ground. A quill that bends rather than snaps still holds too much water.
Much of the bark leaves the valley before this stage is finished. Kerinci has mostly sent its cinnamon out as raw bark that still holds a large share of its moisture, because local producers have limited facilities and limited processing know-how. Rolled bark is typically sold to collectors, who grade it and carry it down the chain to buyers who handle the drying, grinding and packing. The farmer who did the hard work of felling and peeling often receives the smallest part of the final price.
Why the way the bark is cut matters for the forest
Stripping the bark from a standing tree leaves the tree alive. Felling it removes a means of income and a stand of forest in one step. Where bark is taken by clear cutting, the ground loses its canopy, and the wildlife that depends on the forest loses cover and food. The problem is sharpest at the edges of the protected forest, where new cinnamon plots have been planted by farmers looking for land.
Cinnamon is the main reason land is cleared near Kerinci Seblat National Park, which surrounds the valley and borders the slopes of the volcano. Park managers have tried enforcement and programmes that offer farmers other ways to make a living, but the boundary remains contested. Many of the families working the edges say the lines are unclear, and pressure on land is real. Keeping cinnamon inside mixed gardens rather than in cleared blocks is the practical alternative, and many growers already use it because it spreads the risk and keeps the soil covered.
From the valley to the market: value and certification
Most of the money in this spice is made after the bark leaves the highlands. Raw bark is bulky and wet, and finished quills and powder fetch a higher price per kilogram. Some local producers make cinnamon syrup in small home workshops, which adds value and gives families a product they can sell directly to shops and cafes. Ground powder adds further value, though it needs a drier product and a better processing setup than most village households have.
The geographical indication helped establish the name, but meeting export quality standards and the certification demands of foreign buyers is still hard for individual farmers. Farmer groups that take on drying, grading and selling are the most likely route to a better return. For a grower, the lesson is that care at the drying stage matters as much as the tree itself, because a poorly dried quill loses value quickly and cannot be rescued later.
What makes the flavour different from shop cinnamon
The spice is sharp and sweet at once, with a woody depth that carries through a long simmer. It has a slightly bitter edge and less of the delicate, citrus-like lift associated with the thinner Ceylon type. That difference comes from the species. Cassia-type cinnamons are stronger and spicier, and the Korintje tree sits in that group, so the flavour is bolder and a small amount goes a long way.
There is also a practical point about health. Cassia-type bark contains much more coumarin than Ceylon bark. Coumarin is a natural compound that becomes a concern when intake is high over time, so cooks who use this spice every day should treat it as a strong flavouring rather than a bulk ingredient. A few quills in a pot of food for a family is a normal use. Scooping large daily spoonfuls of ground bark into drinks is not.
The strength of the spice also explains why it suits certain dishes better than others. Its bite holds up to slow cooking and to fatty meats, while it can overwhelm a light fruit salad or a delicate custard. Thinking about the dish first, and then the amount of spice, is the simplest way to get a good result.
Cooking with the spice in savoury dishes, drinks and desserts
In savoury cooking, a whole quill goes into stews, braises and rice dishes early in the cooking and comes out before the food is served. The spice pairs well with beef, chicken and coconut-based dishes, and its sweetness rounds off chilli heat. Ground bark appears in spice mixes and rubs, where it should be blended with other spices so that it supports them rather than dominating.
In drinks, a quill steeped in hot water makes a warming tea, and a few pieces can go into a pot of ginger drink or a spiced coffee. Sweet uses include syrups, puddings and cakes. Palm sugar and coconut are natural partners, and the bark’s warmth suits baked fruit, particularly apples, bananas and pumpkin.
Amounts and timing
Because the flavour is strong, start small. A short piece in a large pot is usually enough, and it is better to taste as the dish cooks and add more only if it needs it. The spice gives its best flavour when it has time to infuse, so add it early in a long simmer rather than at the end. For syrups, break the quill into pieces so the bark releases its oils into the liquid, then strain it before bottling.
Buying and storing the quills
Look for quills that are dark brown, hard and fragrant. Break a piece: it should snap cleanly and smell sweet. Dull, dusty or musty quills have either been stored too long or dried poorly. Quills that are thin, pale and papery are a different kind of cinnamon, which is worth knowing if you are paying for the Korintje character.
Store whole quills in a sealed container, away from light and heat, and keep them dry, because moisture is the fastest way to lose flavour and invite mould. Ground spice loses its aroma faster than whole bark, so grinding a small amount just before use gives the most flavour. Whole quills keep their character for a long time when they are stored properly, which makes them a sensible thing to buy in quantity for a household that cooks with them regularly.
Visiting the highlands and the wider region
Visitors to the valley usually come for the volcano, the forest and the local way of life. The Mount Kerinci guide covers the peak and the routes up its slopes. The customs and village life of the highlands are set out in the Kerinci people page, and the regency’s festival of culture and food is a good occasion to taste dishes made with local spices. For the valley’s coffee, see the Kerinci coffee page, which pairs well with a cup of spiced drink after a day among the trees.
Common questions about the spice
Can supermarket cinnamon replace this? It can stand in for a recipe, but the result will taste different. The Korintje bark is more intense, and its woody notes are sweeter and deeper, so reduce the amount when you switch and expect a bolder finish.
How do you tell a good quill from a poor one? Smell and weight. A good quill is fragrant when broken and feels dense in the hand. A light, hollow or dusty quill is usually old or badly dried.
How long does the spice keep? Whole quills keep their flavour well when sealed and kept dry. Ground spice fades sooner, usually well before the quills do, which is why grinding in small batches pays off.
