The beans

Two species, and only one of them is really Vietnam’s

About 97% of Vietnam’s crop is robusta, and that is a fact about altitude rather than preference. The Central Highlands sit between 400 and 800 metres — too low and too warm for good arabica, close to ideal for robusta.

What actually separates them

Ranges across many studies and varieties. A particular lot can sit outside them; the direction of every difference is consistent.

 ArabicaRobusta
Caffeine, % dry weight~0.8–1.6%~1.5–2.7%
Chlorogenic acids~5.5–8%~7–10%
Sucrose~6–9%~3–5%
LipidsHigher~40% lower
Altitude1,200–2,000 m0–800 m
Disease resistancePoorGood
Share of Vietnam’s crop~3%~97%

Two of these do most of the work. Sugar drives roast flavour — most of the sweetness people associate with good coffee comes from caramelisation during roasting, and robusta has roughly half as much to work with. Caffeine is a pesticide — it and the chlorogenic acids are the plant’s defence against insects and fungus, which is why robusta needs less chemical protection in the field and tastes more bitter in the cup.

What Is Vietnamese Robusta?

Robusta is about 97% of Vietnam's crop and the reason Vietnamese coffee tastes the way it does. What the species is, why it grows here, and what fine robusta changes.

Vietnamese Arabica: The 3% Nobody Talks About

Vietnam grows arabica in Lâm Đồng, Sơn La and Quảng Trị — about 1.1 million bags a year. Where it comes from, what it tastes like, and how to brew it.

How Much Caffeine Is in Vietnamese Coffee?

A 20 g phin of Vietnamese robusta works out at roughly 350–450 mg of caffeine — two to four times a normal cup. Here is the arithmetic, and what is estimated in it.
