Vietnamese coffee origins, from Dak Lak to Son La
Vietnam grows roughly 95% Robusta and 5% Arabica, but "Vietnam" on a bag says little about the cup. Region, altitude, picking and processing decide it. Ask for the region, district or farm in your spec and we match you with suppliers who can trace the lot.
Growing regions
| Region | Coffee | Altitude | Notes |
|---|---|---|---|
| Dak Lak (Buon Ma Thuot) | Robusta, some fine Robusta | About 500-800 m | Historical capital of Vietnamese coffee. Basalt red soil, heavy body, low acidity. |
| Gia Lai | Robusta | About 600-800 m | Large Robusta volumes with a profile close to Dak Lak. |
| Dak Nong | Robusta | About 500-800 m | Similar to Dak Lak; mainly natural-processed commercial grades. |
| Lam Dong: Di Linh, Bao Loc | Robusta, fine Robusta | About 800-1,000 m | Higher-grown Robusta, a common source of honey and washed Robusta lots. |
| Lam Dong: Cau Dat, Da Lat | Arabica (Catimor, Bourbon, Typica) | 1,400-1,600 m | Highest commercial coffee terrain in Vietnam. Specialty lots 80-84 SCA, micro-lots 85+. |
| Son La (northwest) | Arabica (mostly Catimor) | Varies by district | The largest Arabica volumes in Vietnam; washed lots traceable to the commune. |

Robusta
Buon Ma Thuot in Dak Lak sits on basalt-rich red soil at 500-800 m. Standard Robusta here delivers a heavy body, low acidity and the bitter-chocolate backbone that espresso blends in Italy, Spain and Eastern Europe rely on. Natural processing dominates; honey and washed lots come from selected mills.
Fine Robusta
Selective red-cherry picking, controlled drying and careful storage turn Robusta into a coffee that is sold by cup score. Volumes are small and lots are traceable to a farm or group of farms, which suits independent roasters.
Arabica
Cau Dat's Catimor, Bourbon and Typica cup brown sugar, stone fruit and citrus. Second-generation specialty farmers produce washed, natural and honey micro-lots. Son La supplies larger volumes of washed Catimor for blends.
Harvest and shipment calendar
| Coffee | Harvest | New-crop shipment |
|---|---|---|
| Robusta, Central Highlands | Roughly November to January | New-crop lots usually ship from late December to April |
| Arabica, Cau Dat and Da Lat | Roughly October to January | Washed and natural lots usually offered from January |
| Arabica, Son La | Roughly October to December | Washed lots usually offered from December to March |
Timing shifts with weather each year. Put the crop year and shipment month in your spec.
Processing methods
| Process | How it is done | Effect on the cup |
|---|---|---|
| Natural (dry) | Whole cherry dried on patios, raised beds or mechanical dryers, then hulled | Heavy body, chocolate and earthy notes; the default for Vietnamese Robusta |
| Honey | Skin removed, cherry dried with some mucilage on the parchment | Sweeter and rounder than natural; used for fine Robusta and some Arabica |
| Washed | Pulped, fermented or mechanically demucilaged, washed, dried in parchment | Cleaner, brighter cup; standard for Cau Dat and Son La Arabica |
| Wet polished | A finishing step after hulling that removes silver skin | Visual quality and cleaner appearance; limited effect on flavor |
| Anaerobic / experimental | Controlled fermentation in sealed tanks or with selected yeasts | Distinct fruit and wine notes; small specialty lots only |

Origin questions
Which Vietnamese region has the best Robusta?
It depends on the cup you want. Dak Lak and Gia Lai supply the classic heavy, chocolate-leaning Robusta in volume. Higher-grown Lam Dong (Di Linh, Bao Loc) and selectively picked farms in Dak Lak are the usual sources of fine Robusta with more sweetness and cleaner acidity.
Where does Vietnamese Arabica come from?
Mainly from Lam Dong (Cau Dat and Da Lat, 1,400-1,600 m) in the south and Son La in the northwest. Cau Dat is the source of most specialty lots; Son La supplies larger volumes of washed Catimor.
Can I buy a single-farm lot from Vietnam?
Yes, especially for Arabica from Cau Dat and fine Robusta. Single-farm lots are small, often a few hundred kilograms to a few tonnes, and are usually sold vacuum-packed or in lined jute bags. Mention the farm or district in your spec.
When should I request new-crop samples?
For Robusta, from late December once the first new-crop lots are dried and graded. For Cau Dat Arabica, from January. Pre-shipment samples should always come from the lot that will be loaded.
