There are trades where timing matters more than technique. Peeling cinnamon bark is one of them. The same worker, the same tree: in season the bark comes away in whole sheets; out of season it clings and breaks into pieces.
The reason lies in the tree. Bark separates easily from the wood only when the tree is moving sap strongly. In Vietnam, people in the trade usually speak of two seasons in a year, one around the beginning of the year and one around the end of summer, and the exact timing shifts with the region and with each year's weather.
The steps, put briefly
- Choosing the tree: by age and by bark thickness, not taking trees that are still too young.
- Scoring: cutting along and across to divide the bark into sheets of a usable size.
- Lifting: using a thin tool between bark and wood to take off a whole sheet.
- Working the inner face: cleaning off what still clings, depending on the intended use.
- Drying: in shade with air movement, turning the sheets so they curve evenly into one shape.
The curl is part of the craft
As it dries, the sheet rolls up along its own direction, and how much it rolls depends on the thickness, on the diameter of the trunk and on how it was dried. This is why lengths of cinnamon bark are never alike, and why the sorting has to happen after drying rather than while the bark is still fresh.
In our workshop, only lengths whose curves match can be joined into a vessel that closes properly. This cannot be chosen in advance; the bark has to be fully dry and rested before pairs can be matched. This is how we work in our workshop.
Why out of season is a poor decision
Three common consequences: a high breakage rate so the usable share drops, an inner face left fibrous with wood still attached so it needs extra work, and a thinner smell because the tree is not in a favourable state. For someone buying raw material, an out-of-season batch may cost less, but the loss usually eats up the saving.
A few questions you often send us
Does peeling the bark kill the tree
It depends on the method. There is harvesting that takes the whole tree, and there is partial peeling that lets the tree go on living. This is a question to ask the material supplier, because it relates to how the planted forest is managed.
How many times a year can bark be taken
Usually by season rather than by wish. Peeling intensively adds no yield and only harms the tree and lowers the quality of the bark.
How do thick and thin bark end up being used differently
Thick bark holds its shape well so it goes to pieces that need form; thin bark breaks more easily so it usually goes into the grinding, oil distillation or spice group.
