The Short Version
Forget the Robusta stereotypes; Vietnam’s high-altitude Lam Dong highlands are producing world-class specialty Arabica. By mastering precise processing and technical light roasts, growers are transforming misunderstood varieties like Catimor into sophisticated, fruit-forward highlights of the Vietnamese terroir.

Most international drinkers associate Vietnamese coffee exclusively with Robusta served through a phin with condensed milk. While Robusta remains the country’s agricultural backbone, a different story is unfolding in the high-altitude forests of Cau Dat. Above 1,600 meters in the Lam Dong highlands, growers are producing specialty Arabica that challenges these monolithic perceptions of Vietnamese coffee.
Washed lots tend to show cleaner acidity, naturals lean fruitier and heavier, and honey sits in between with more sweetness and body.
High Altitude Varieties and Processing
The Siori Coffee family has been cultivating these trees since 1995, managing small gardens in Cau Dat and Ta Nung commune. Under a forest canopy, they manage several distinct varieties including Typica, Bourbon, and the aromatically unique Moka. The processing methods—natural, honey, and fully washed—dictate much of the final cup profile. In this region, washed lots typically present a bright, fruit-like acidity and light bitterness, whereas honey processed lots offer more sweetness and a rounder body.
Washed lots tend to show cleaner acidity, naturals lean fruitier and heavier, and honey sits in between with more sweetness and body. This technical precision allows producers like Công Hoàng, who spent a decade in quality control at Mercafe, to approach their own harvest with a rigorous, analytical eye.
The Catimor Challenge
Despite the success of heirloom varieties, Catimor remains a dominant presence in the region. Due to its Timor Hybrid parentage, the variety often carries a so-so reputation within specialty circles. When roasted lightly, Catimor is frequently criticized for being thinner or less sweet than its Typica or Bourbon counterparts. Rather than masking these characteristics in dark blends, there is a growing movement to treat Catimor with the respect of a specialty light roast.
The difficulty lies in managing the coffee’s specific density and sugar profile during extraction. For those working with lower-density beans, the technical variables of brew temperature, grind size, and water-to-coffee ratios become critical to avoiding a flat or underwhelming cup. Mastering these nuances could turn a misunderstood variety into a legitimate highlight of the Vietnamese high-altitude terroir.
If you are brewing a thin-bodied light roast, do you prefer adjusting your grind fineness or your water temperature first?
Questions & Answers
What are the main differences between washed, natural, and honey processed coffee?
The main differences between these processing methods lie in their acidity, sweetness, and body. Washed lots typically present a bright, fruit-like acidity accompanied by a light bitterness. Natural processing results in a fruitier and heavier cup profile, while honey processing sits in between the two. Specifically, honey processed lots offer more sweetness and a rounder body compared to the cleaner acidity found in washed varieties.
Why is Catimor coffee often criticized in specialty coffee circles?
Catimor is frequently criticized because it can be thinner or less sweet than heirloom varieties like Typica or Bourbon when roasted lightly. This reputation stems from its Timor Hybrid parentage, which affects its specific density and sugar profile. While many traditional roasters mask these traits in dark blends, specialty producers are now attempting to treat the variety with more respect through precise light roasting techniques.
How does altitude affect coffee production in the Lam Dong highlands?
High altitudes allow growers to produce specialty Arabica that differs significantly from the country's standard Robusta. In the Lam Dong highlands, coffee is grown above 1,600 meters in high-altitude forests such as Cau Dat. This specific environment and elevation support the cultivation of distinct varieties including Typica, Bourbon, and the aromatically unique Moka, which challenge the monolithic perception of Vietnamese coffee as being exclusively Robusta.
What technical variables are important when brewing lower-density coffee beans?
Managing brew temperature, grind size, and water-to-coffee ratios is critical when brewing lower-density beans like Catimor. Because these beans have specific density and sugar profiles, precise technical control is necessary to avoid a flat or underwhelming cup. Mastering these specific variables allows brewers to successfully extract the nuances of the bean, potentially turning a misunderstood variety into a legitimate highlight of the high-altitude terroir.
