ROBUSTA COFFEE
1.Plant and bean characteristics
- Species: Coffea canephora, commonly called Robusta. It is generally hardier, more disease-resistant, and more productive than Coffea arabica. Robusta usually grows well at lower to mid elevations.
- Bean appearance: Robusta beans are typically rounder and thicker than Arabica beans. They contain less oil and sugar on average.
- Caffeine content: Robusta contains significantly more caffeine than Arabica, which contributes to its stronger, more bitter sensation (commonly cited ranges: Robusta about 2–3% caffeine vs Arabica about 1–1.5%).
2.Flavor and cup profile
- Typical flavor: Robusta is often described as more full-bodied and robust — with pronounced bitterness and woody, nutty, or chocolatey notes. It can also present earthy or smoky tones.
- Acidity and body: Acidity (brightness) is generally lower than in Arabica, while body is heavier.
- Espresso characteristics: Robusta tends to produce a thicker crema and is frequently used in espresso blends to add body, crema, and a stronger flavour punch.
