Cau Dat: where Vietnam grows its best Arabica
1. Where Cau Dat is, and why it matters
Cau Dat is a small commune about 24 kilometers east of Da Lat city in Vietnam’s Lam Dong province. It sits at roughly 1,500 meters above sea level on the southern edge of the Central Highlands. By land area, it’s tiny. By reputation, it’s the most important Arabica-growing region in a country famous for Robusta — and the only place in Vietnam that produces Arabica at consistent specialty-grade quality.
Vietnam grows roughly 40% of the world’s Robusta. Cau Dat is the exception that proves the rule: a small island of high-altitude Arabica land, surrounded by hundreds of thousands of hectares of lower-altitude Robusta country. Almost every memorable Vietnamese Arabica you’ve ever tasted came from here.
We work directly with cooperative partners in Cau Dat to source the Arabica behind two of our coffees — our single-origin Arabica from Cau Dat Lam Dong, and the 30% Certified Organic Moka component of our Hippie Trail Blend.
2. The terroir
What makes Cau Dat work is three things stacking on top of each other.
The altitude is right. Arabica wants 1,200-2,000 meters of elevation; Cau Dat sits comfortably in the middle of that window at around 1,500 m. At that altitude, daytime temperatures peak in the low-to-mid 20s Celsius and nighttime temperatures drop into the low teens. That diurnal swing slows the maturation of the coffee cherry, which concentrates sugars and develops more complex acid structure in the bean. It’s the same mechanism that makes Ethiopian and Colombian Arabica grow well at altitude.
The soil is volcanic basalt — deep, well-drained, rich in minerals — left behind by the geological history of the Central Highlands. Coffee farmers in the region describe the soil as “red earth,” and you can see it everywhere in the landscape. Basalt soil is one of the great correlates of specialty coffee, from the Brazilian cerrado to the Costa Rican mountains to the slopes of Mount Elgon in Uganda.
The climate adds the third ingredient: about 1,500 mm of annual rainfall, high humidity (often around 80%), and a clear dry season that aligns with harvest. The combination of consistent rain through the growing season and dry weather at harvest time is unusually favorable — many Arabica regions have to fight one or the other.
Few places in Southeast Asia put all three of these together. Cau Dat does, and the cup shows it.
3. The four cultivars grown in Cau Dat
Cau Dat farmers grow four Arabica cultivars, each with a different history and a different cup.
Bourbon is one of the original heirloom Arabica varieties, named for the French island where it was first cultivated centuries ago. It’s prized for sweetness and complexity — caramel, red fruit, balanced acidity. Bourbon is also vulnerable to disease and yields less per tree than newer hybrids, so growing it is a deliberate choice toward quality over volume. Yellow Bourbon, which we offer in smaller-format bags, is a mutation of the classic red Bourbon with a slightly different cup — more honey, more stone fruit.
Typica is the other classic heirloom — the variety from which most modern Arabica cultivars descend. Typica tends toward elegance and clean cup character, with a softer body than Bourbon and a delicate floral aroma. Like Bourbon, it’s lower-yielding and disease-prone.
Mocha (sometimes written “Moka”) is a small-bean Arabica variety with a long history in Yemen and Ethiopia. In Cau Dat, Mocha produces some of the most distinctive cups in Vietnam — concentrated sweetness, dried fruit, sometimes a wine-like character. The Certified Organic Moka in our Hippie Trail Blend comes from these plantings.
Catimor is a hybrid bred for disease resistance and yield. It’s the most-planted Arabica cultivar in Cau Dat by area because farmers can rely on it. Catimor’s cup is honest but less distinguished than Bourbon, Typica, or Mocha — typically lower acidity, lower complexity, and serviceable but not exciting. The best Cau Dat farms reserve their Catimor for blends and keep their heirloom plantings for single-origin lots.
When you see “Arabica from Cau Dat” on a label, the cultivar mix matters. Our Arabica from Cau Dat Lam Dong is a Bourbon-Typica selection chosen for cup character rather than yield.
4. Processing in Cau Dat
Most Cau Dat Arabica is wet-processed (washed). Cherries are depulped on the same day they’re picked, fermented in tanks for 18-36 hours depending on temperature, then washed and dried on raised beds or patios. The wet process suits the region’s clear dry season at harvest and produces clean, structured cups that let the cultivar character come through.
A small but growing share of Cau Dat coffee is honey-processed or naturally processed. Honey processing — depulping but leaving the mucilage on the bean for drying — adds sweetness and body to the cup without the heavier ferment notes of full natural processing. Natural-processed Cau Dat is the experimental edge of the region; lots are small but the cups can be remarkable.
Quality-focused cooperatives also use density-sorting, screen-size grading, and hand-picking of defects to lift the green coffee to specialty-grade standards. The presence of this kind of post-harvest infrastructure — and the trained labor to operate it — is part of what separates Cau Dat from other Arabica-curious regions in Vietnam.
5. The cup — what Cau Dat Arabica tastes like
Well-processed Cau Dat Arabica has a recognizable profile.
Acidity is medium and clean — apple-and-pear bright, sometimes citrus — without the high-toned tartness of an Ethiopian washed. Body is medium to medium-full. Sweetness is consistent and lingering, often described as caramel, honey, or brown sugar. Aromatic notes regularly include fresh avocado, walnut, fresh bread, and caramel — a comforting, breakfast-table profile.
Heirloom Bourbon and Typica lots add complexity on top of this base: red fruit, dark chocolate, a longer finish. Mocha lots can layer in dried apricot, fig, and a deeper sweetness. Catimor-heavy lots taste like a clean, simple, reliable coffee — pleasant rather than memorable.
Compared with other origins: a good Cau Dat sits somewhere between a Colombian Huila and a washed Sumatran. It has the cleanliness and structure of a Latin American Arabica with a touch more body and a slightly heavier mouthfeel.
6. The Starbucks recognition — and what it means
In 2016, Starbucks accepted Cau Dat Arabica into its global supply chain under the Coffee and Farmer Equity (C.A.F.E.) Practices program, making it one of only a handful of regional coffees Starbucks sources globally under that designation. The recognition matters less for the brand association than for what it signals: a major buyer with rigorous green-coffee standards has validated, at scale, that Cau Dat can produce Arabica meeting international specialty benchmarks.
That validation has accelerated investment in the region — more cooperatives, more processing infrastructure, more agronomy support, more farmers willing to plant heirloom cultivars rather than yield-optimized hybrids. The Cau Dat available today is meaningfully better than the Cau Dat available a decade ago, and the trajectory is still up.
7. How Megawatt sources from Cau Dat
We are a Canadian-Vietnamese team based in Vietnam, which means our relationship with Cau Dat cooperatives is direct and on-the-ground rather than mediated through international green-coffee traders.
In practice, that means we visit the farms during harvest. We participate in cupping the new lots before we commit. We pay above market rates for the cultivar mix and processing standards we want, and we buy in quantities small enough that the cooperative can invest selectively rather than chasing volume. Roasting happens in Vietnam, close to the green coffee, in small batches — which keeps the supply chain short and the coffee fresh.
This direct sourcing is also why we can offer Cau Dat Arabica at sensible prices. Most Cau Dat Arabica that reaches international buyers has passed through two or three intermediaries before it gets there. Ours hasn’t.
The Arabica from Cau Dat Lam Dong we sell — in 250 g, 500 g, and 1 kg bags — is the same coffee we’d serve at our own table. Our Hippie Trail Blend uses Certified Organic Moka from a smaller cooperative in the same growing area, blended 30/70 with our medium-dark roasted Fine Robusta.
8. How to brew Megawatt’s Cau Dat Arabica
This is an Arabica that rewards classic brewing methods.
Pour-over is probably the best showcase for the cultivar character. Use 15 g coffee to 250 g water, water at 94-95°C, a medium grind, and a 3-minute total brew time. The cup will be balanced, clean, and let the Bourbon-Typica notes come through.
French press brings out body and sweetness. 30 g coffee to 500 g water, coarse grind, 4 minutes, then plunge.
Phin (Vietnamese drip) is a traditional choice and produces a more concentrated, intense cup — works particularly well with the Hippie Trail Blend, where the Robusta adds body.
Espresso is possible but ask for a slightly coarser grind than your usual Arabica and pull a slightly longer ratio (1:2.2 or 1:2.5) to avoid thin, sour shots.
9. Frequently asked questions
Is Cau Dat coffee Arabica or Robusta? Cau Dat grows almost exclusively Arabica. It is, in fact, the only region in Vietnam producing specialty-grade Arabica at scale. The rest of Vietnam — including most of Lam Dong province — grows Robusta.
What’s the elevation of Cau Dat? Roughly 1,500 meters above sea level. That elevation is what makes Arabica viable here when most of Vietnam is too low and too hot.
What cultivars are grown in Cau Dat? Four main cultivars: Bourbon, Typica, Mocha, and Catimor. The first three are heirloom varieties prized for cup quality. Catimor is a higher-yielding hybrid.
Is Cau Dat Arabica organic? Some lots are certified organic, including the Moka component of our Hippie Trail Blend. Others are not formally certified but are grown with low-input methods. Certification is a separate question from cup quality.
Why was Cau Dat selected by Starbucks? In 2016, Cau Dat Arabica was accepted into Starbucks’s C.A.F.E. Practices supply chain — a recognition of consistent specialty-grade quality. The acceptance helped accelerate investment in the region.
How is Megawatt’s Cau Dat Arabica different from generic Vietnamese Arabica? We work directly with specific cooperatives, select the cultivar mix, pay above market for the quality standards we want, and roast in Vietnam. Most Vietnamese Arabica sold abroad passes through multiple intermediaries and arrives months after roasting.
