Where coffee wood dog chews come from: the tree and the farm

Auf Deutsch: Woher Kaffeeholz für Hundekausnacks kommt: der Baum und der Hof

Almost every supplier of this product says the same sentence: made from old coffee trees, a by-product, sustainable. It is a sentence that costs nothing to write and tells a buyer nothing they can check. This page sets out the part that is checkable — who decides when a coffee tree comes down, how much wood that releases in a year, and why stems from young trees are thrown away. Those three facts explain most of what a buyer actually wants to know: whether the supply will still be there next season, and whether the sustainability line survives contact with a compliance officer.

1. Who decides when the tree comes down

A coffee tree is a farm's income. Nobody removes one that is still yielding well, and no chew order is large enough to change that arithmetic. The decision belongs entirely to the farmer, and it is made on one basis: the tree has aged past the point where its cherry yield justifies the space, the fertiliser and the labour it consumes.

When it does, the farmer takes the tree out and puts a young one in its place. The stems are then a problem to be cleared rather than a product to be sold — which is where WINVN INT comes in, after the decision, not before it.

Whether this counts as a forest product in law is a separate question with a separate answer, and it is the one an EU buyer has to satisfy their own compliance team on. It is worked through on the EUDR page.

2. The arithmetic of a coffee farm

This is the section that explains why supply behaves the way it does.

Put together, those figures describe a supply that is collected rather than harvested. Buying volume means visiting many plots across a season and taking what each one releases, which is slower and more expensive per tonne than cutting a stand, and it is the reason a serious quantity of this material cannot be assembled in a hurry at any price.

It also sets a practical test a buyer can apply to any supplier, including this one. Ask how the material is accumulated and how far ahead stock is committed. A supplier working from real plots will describe a collection season and a holding period. A supplier who answers that volume is unlimited and available immediately is either selling someone else's stock or describing a different material.

3. Why stems from young trees are rejected

Not all coffee wood is usable, and the age of the tree it came from is the single biggest predictor. WINVN INT does not take stems from trees under 20 years old, for two reasons that all end up in the same place — a complaint from the buyer's customer several months later.

• The wood is not hard enough. Density builds with age. A stem from a young tree gives a chew that goes down far faster than the same size cut from an old one, and the end user reads that as a product that does not last.
• Young stems attract borers. Softer wood is more prone to insect damage, and damage that is invisible at packing is very visible after five weeks in a container.

Age is not a claim a buyer has to take on trust, either. A coffee stem lays down one growth ring a year, so the rings on a cut face are a rough count of the tree's life. It is not laboratory evidence, but it is more than most suppliers will let you check with your own eyes on a sample.

4. What the wood would otherwise have been

The honest baseline for anything sold as a by-product is what happened to it before there was a buyer. For coffee stems on most Central Highlands farms, the answer is firewood, or clearing and burning at the edge of the plot.

That is the whole of the environmental claim WINVN INT is prepared to put in writing, and it is deliberately narrow: this is material that already exists, that had an established low-value use, and that now returns a second payment to the farmer from a tree that has stopped paying. Everything past that point — carbon figures, offset arithmetic, net-zero language — WINVN INT has not measured and therefore does not publish.

Buyers who need a sustainability story that survives a compliance review generally prefer this shape of answer to a longer one. A narrow claim you can evidence beats a broad claim you cannot.

5. From standing stem to sorted billet

Between the plot and the workshop there is a short sequence that decides how much of the material survives.

1. Cut to billet in the plot. Stems are cut to billets where they fell. Forks are trimmed off at this stage, because carrying them wastes truck space that has to be paid for either way.
2. Sorted by diameter on arrival. Billets are separated into size classes before storage, not after. Thin material and thick material dry at different rates, so they are stacked apart; mixing them is how a batch ends up with some pieces over-dry and cracked and others still wet in the core.
3. Stacked in ventilated shade. Out of direct sun, under cover, with air able to reach the stack. Sun on a stack of green billets is the fastest way to split them, which is the reason this step looks unhurried and expensive and is neither.

Machining happens against orders, not into stock — the surface finish of a piece degrades in storage far faster than the billet it was cut from does.

6. Between the farm and the factory

The single most important thing about this material is also the least visible: after it is cut and sorted, it sits. Wood that has not come down to a stable moisture content in its own time will do it later, in a sealed steel box, on somebody else's ocean freight.

Two consequences follow, and both matter commercially.

• Lead time and supply are different clocks. The underlying supply moves at the speed of replanting. A buyer planning a Q4 range is negotiating against stock that already exists; a buyer asking for a step change in annual volume is negotiating against next year's collection.
• Stock is what a supplier can honestly commit against. Anyone quoting large volumes against a season that has not happened is passing you a risk rather than a price.

WINVN INT publishes the outcome of the drying and conditioning work rather than its recipe — the temperatures, durations and stage order are treated as proprietary and are not on this site. What is available to a buyer is the result: moisture measured below 14% at the factory. The mechanics of why that number decides whether a shipment arrives clean are on the moisture and mold page.

7. Why the region is part of the specification

Vietnam's Robusta belt sits in the Central Highlands — Dak Lak and Gia Lai. Two features of it are relevant to a chew rather than to a cup of coffee.

• Basalt soil and plantation age. These are established coffee provinces on their second and third replanting cycles, which is what makes a steady flow of genuinely old stems available at all. A young coffee region does not have this material to sell yet.
• A defined dry season. Ambient conditions do a large part of the work that a kiln would otherwise have to do fast and badly. Wood brought down in air over months behaves differently in a container from wood pushed down in hours with heat.

WINVN INT identifies the region and names the provinces. Individual farms and plot locations are not published, for the ordinary reason that a supply relationship built over years is not something to hand to a competitor with a screenshot.
