f a Laotian coffee has ever crossed your cup, there is a good chance it was robusta, full-bodied and bitter, the kind of bean that goes into blends and instant coffee by the ton. That is one story Laos tells. It is not the only one.
High on the Bolaven Plateau in the cool, volcanic south, a second story is taking shape. Arabica planted at altitude is being picked, washed, and sold as specialty, with a softer, sweeter, chocolate-and-caramel cup that has little in common with the bulk robusta below it. Same country, same plateau, two completely different drinks.
Once you know that Laos is split this way, a bag stops being a guess. The word arabica, the name Bolaven, an altitude figure, all of these tell you which of the two coffees you are about to brew before you ever grind it.
Two stories on one plateau
Almost all of Laos coffee grows in one place: the Bolaven Plateau in the south, spread across the Champasak, Salavan, and Sekong provinces. It is a high, cool plateau with volcanic soil, and both robusta and arabica are grown on it, separated mostly by elevation. The structure is largely smallholders and cooperatives, with a few estates.
The single most useful thing to know about Laos is that it is not a single-profile origin. Most of the volume is robusta, a hardy species grown for body and price, much of it heading into blends and instant coffee. The specialty story is the smaller, higher-grown arabica. When people talk about Laos as a specialty origin, they almost always mean the Bolaven Plateau washed arabica, not the robusta bulk below it.
Where it grows
The Bolaven Plateau does the work here. Sitting high in the south, it pairs cool plateau air with volcanic soil, the kind of combination that tends to slow cherry ripening and build a denser, cleaner bean. The plateau is why Laos has a specialty story at all: the same height and climate that suit arabica also give the cup its rounded, clean character.
Height splits the two crops. Robusta grows lower, roughly 600 to 1000 meters, where it is hardy and productive. Arabica climbs higher, roughly 1000 to 1350 meters on the plateau, where the cool air and slow ripening favor the sweeter, more delicate cup that specialty buyers look for. Harvest runs roughly November to February, with the peak around December and January.
Robusta and arabica
Two species share the plateau, and they are genuinely different coffees. Robusta is the volume crop, the hardy lower-grown species behind most of the country output. Arabica is the smaller, higher-grown crop that carries the specialty story.
| Crop | Where on the plateau | Typically known for |
|---|---|---|
| Robusta | Lower, about 600 to 1000 m | The volume crop; full body, low acidity, woody, earthy, bitter |
| Arabica | Higher, about 1000 to 1350 m | The specialty crop; medium body, soft acidity, chocolate, caramel, nut |
On the arabica side, the plantings you are likely to meet are Typica, Bourbon, and Catimor. The quality-focused lots that drive the specialty story tend to be the Typica and Bourbon, the older, more refined varieties, while Catimor is a more productive, disease-resistant choice. When a Bolaven Plateau bag leans into its variety, a Typica or Bourbon is usually the one being celebrated.
What it tastes like
Laos robusta tastes the way good robusta tends to taste: full-bodied and low in acidity, with woody and earthy notes and a frank bitterness. It is built for body and strength, the backbone of a blend more than a coffee you sip black to study. That is its job, and it does it well.
The specialty Bolaven Plateau arabica is a different drink. It tends toward a medium body and a soft-to-moderate acidity, with chocolate, caramel, and nut leading, and a mild citrus or stone-fruit lift underneath. The volcanic soil and cool plateau climate show up as a clean, rounded cup rather than a loud or wild one. It is approachable and balanced, easy to like.
How it is processed
Processing tracks the split too. The commodity robusta is mostly handled as natural, dried whole, or washed at scale, the volume-friendly routes. The specialty arabica is increasingly washed, with a growing number of honey and natural lots as producers reach for the quality and the cup that specialty buyers reward.
Washed
fruit removed, seed fermented and rinsed clean
or Honey
some sticky fruit left on during drying
or Natural
whole cherry dried in the sun
Dried and hulled
then graded and exported
For the specialty arabica, washed is the route most associated with the clean, chocolatey, rounded cup the plateau is building its name on. The fruit is stripped off and the seed is fermented and rinsed before drying, which keeps the cup clear and lets the sweetness sit underneath. Honey and natural lots, where some or all of the fruit stays on through drying, add more fruit and body, and they are growing as producers experiment toward specialty markets.

Reading a Laos bag
Because Laos is split, the label matters more than usual. The first thing to find is the species. The word arabica points you at the specialty story; without it, especially on cheaper or blend-bound coffee, you are most likely looking at robusta. An altitude figure helps confirm it, since the specialty arabica sits higher on the plateau.
Next, look for the place and the process. A bag that names the Bolaven Plateau, or a cooperative on it, and that says washed, is signalling the high-grown specialty cup, the soft, chocolatey, clean one. A named variety like Typica or Bourbon is another good sign that the lot is quality-focused rather than bulk.
Common questions
- Where does coffee grow in Laos?
- Almost all of it grows on the Bolaven Plateau in the south, across the Champasak, Salavan, and Sekong provinces. It is a high, cool plateau with volcanic soil. Both robusta and arabica grow there, separated mainly by altitude, with a structure of smallholders, cooperatives, and a few estates.
- Is Laos coffee robusta or arabica?
- Both, and the difference is the whole point. Robusta is the volume crop, grown lower at roughly 600 to 1000 meters for body and price. Arabica is the smaller, higher-grown crop at roughly 1000 to 1350 meters on the Bolaven Plateau, and it carries the specialty story. When people talk about specialty Laos coffee, they mean the high-grown arabica.
- What does specialty Laos coffee taste like?
- The specialty Bolaven Plateau arabica tends toward a medium body and a soft-to-moderate acidity, with chocolate, caramel, and nut leading, plus a mild citrus or stone-fruit lift. The volcanic soil and cool plateau climate show up as a clean, rounded cup. Laos robusta is a different drink: full-bodied, low in acidity, woody, earthy, and bitter.
- How is Laos coffee processed?
- Commodity robusta is mostly natural, dried whole, or washed at scale. The specialty arabica is increasingly washed, with a growing number of honey and natural lots as producers target specialty buyers. Washed is the route most associated with the clean, chocolatey cup the plateau is becoming known for.
