Vietnamese Coffee: Robusta, Arabica and the Central Highlands
Quick answer: Vietnam is the world's second-largest coffee producer and, by a wide margin, a robusta country: of the 31.7 million 60 kg bags harvested in 2025/26, about 30.5 million were robusta and 1.2 million arabica (USDA, May 2026). Five Central Highlands provinces hold 92% of the planted area. Arabica is a niche, grown around Da Lat in Lam Dong and in the north-western provinces of Son La and Dien Bien, almost entirely as Catimor.
- Output: 31.7 million bags in 2025/26, with 32.5 million forecast for 2026/27 (USDA, May 2026)
- Arabica is roughly 3 to 4% of the crop; robusta covers about 644,000 harvested hectares
- Dak Lak, Lam Dong, Dak Nong, Gia Lai and Kon Tum hold 92% of coffee area and 90% of output
- Nearly 99% of Vietnamese arabica is Catimor (ICO country profile)
- Fine robusta means 80 points or more on the Coffee Quality Institute's robusta protocol
- TR4, a Dak Lak clone approved in 2006, is the best-documented robusta variety
- About 30% of the coffee area is 20 years old or more and needs replanting
How big is Vietnamese coffee, and how much of it is arabica?
Start with the arithmetic. Output rose from 29 million bags in 2024/25 to 31.7 million in 2025/26, and the USDA forecasts 32.5 million for 2026/27, split into 31.4 million robusta and 1.1 million arabica. That puts arabica at roughly 3 to 4% of the crop. Robusta alone covers about 644,000 harvested hectares, out of some 730,000 hectares of coffee overall.
Most of it leaves the country: 28.5 million bags were exported in 2025/26, while about 5 million bags a year stay home (2026/27 forecast). The ICO's profile for its 124th Council session adds a productivity footnote: at around 2.3 tonnes per hectare, Vietnam's yield was higher than any other producer's.
Where in the Central Highlands is the coffee?
The USDA names five provinces, Dak Lak, Lam Dong, Dak Nong, Gia Lai and Kon Tum, and credits the region with 92% of coffee area and 90% of national output. The ICO's 2017 acreage shows how lopsided even that group is: Dak Lak 190,000 hectares, Lam Dong 162,000, Dak Nong 135,000, Gia Lai 82,000 and Kon Tum 13,500. Buon Ma Thuot is Dak Lak's coffee capital; Pleiku plays the same role in Gia Lai.
The setting does a lot of the work: volcanic soils, moderate elevation, and a wet season followed by a pronounced dry one. That last feature is both an asset and a liability, as the water section below explains.
Robusta gets its own grading system
Robusta was long sold on volume and price. The Coffee Quality Institute (CQI) now runs a separate evaluation protocol and a Q Robusta Grader certification, and labels any lot scoring 80 points or more as fine robusta. The score sheet differs from the arabica one mainly in how it handles saltiness and the bitter-sweet balance, since robusta carries more chlorogenic acids; low saltiness is rewarded.
Producers in Dak Lak, Dak Nong, Gia Lai and Lam Dong now offer lots picked ripe and processed washed, honey or natural, a few with anaerobic fermentation. Natural drying is the traditional route; the other methods followed specialty demand. Expect cocoa, nuts, spice and a heavy body. Sweetness rather than harshness is the signal that a lot deserves the label.
TR4 and the clones behind the yield
World Coffee Research profiles TR4 as a robusta clone whose mother tree came from a farm in Dak Lak. The Western Highlands Agroforestry Science Institute (WASI) developed it, and Vietnam's agriculture ministry approved it in 2006. Potential yield is 5,000 to 7,000 kg of green coffee per hectare, beans are medium (screen 15 to 16), and the best altitude is 500 to 800 m. Robusta needs cross-pollination, so TR4 is planted with other clones; WCR lists TR9, TR11 and TRS1 among related selections.
Replanting is a project in itself. About 30% of the coffee area is 20 years old or more (USDA, 2026), and WASI supplies roughly 4 to 5 million plants a year (USDA, 2025).
Water is the bottleneck
Robusta in the Highlands does not get through the dry season without irrigation. The ICO profile calls traditional irrigation largely obsolete and a cause of serious groundwater loss. A field study reported by World Agroforestry (ICRAF, 2022) found farmers applying 700 litres per tree per round, against the 400 to 500 litres WASI recommends in harvest years. The 2016 drought hit more than 165,000 hectares badly.
Costs add pressure: the USDA reports fertiliser and fuel up about 30% and labour up 33%, with rainfall below normal from January to March 2026. A projection cited in the ICO profile suggests Vietnam could lose half of its current robusta-growing area by 2050 if temperature and rainfall shift as modelled.
Arabica in Da Lat, Cau Dat and the north-west
Arabica came first. French missionaries introduced it in 1857; robusta and excelsa followed in 1908. In Lam Dong, the Da Lat uplands kept the tradition, and Cau Dat, about 25 km south-east of the city and above 1,450 m, is the name most often cited for quality arabica, with Bourbon, Typica and Catimor in the ground. In the cooler air, ripening is slower and the cup brighter and lighter than a plateau robusta.
North-west Vietnam, around Son La and Dien Bien, is the main mountain arabica zone outside Da Lat, and Khe Sanh in Quang Tri sits much lower, at 350 to 500 m (VietCoffee). Catimor, descended from the Timor Hybrid and Caturra, accounts for nearly all of it. It brings rust resistance, but a cup often judged plainer than Bourbon or Typica, so picking ripe cherries and careful processing decide the result.
Regions at a glance
These cup notes are tendencies rather than rules.
| Zone | Species and varieties | Indicative altitude | Cup tendency |
|---|---|---|---|
| Dak Lak, Dak Nong, Gia Lai, Kon Tum | Robusta (clones such as TR4) | plateaus, roughly 500 to 800 m | heavy body, cocoa, nuts, restrained bitterness |
| Lam Dong (Da Lat, Cau Dat) | Arabica (Bourbon, Typica, Catimor) | above 1,450 m | brighter acidity, lighter body, fruit |
| Son La, Dien Bien | Arabica (Catimor) | north-western mountains | soft cup, moderate acidity, process-dependent |
| Quang Tri (Khe Sanh) | Arabica (Catimor) | 350 to 500 m | round, low acidity |
What to look for on the bag
Check the species, province, process, harvest year and, where given, the CQI score. A fine robusta works as a short espresso or a filter brew; Da Lat arabica can be dialled in like any high-grown arabica. For the species comparison, see our arabica versus robusta guide, and for the traditional serve, the phin iced coffee recipe.
Frequently asked questions
Is Vietnamese coffee only robusta?
No, but almost: arabica was 1.2 million of 31.7 million bags in 2025/26, under 4%. It comes from Da Lat in Lam Dong and from Son La and Dien Bien, and about 99% of it is Catimor.
What makes a robusta fine?
A score of 80 points or more on the Coffee Quality Institute's robusta protocol, which has its own treatment of saltiness and bitterness. Ripe picking and careful washed, honey or natural processing are the usual route.
Which Vietnamese province grows the most coffee?
Dak Lak, around Buon Ma Thuot, with 190,000 hectares in 2017 (ICO), ahead of Lam Dong at 162,000. The Central Highlands as a whole hold 92% of coffee area.
Is TR4 an arabica variety?
No. TR4 is a robusta clone from Dak Lak, developed by WASI and approved in 2006, with a potential yield of 5,000 to 7,000 kg of green coffee per hectare.
