Specifications for Indonesian Robusta Coffee Beans

Grown throughout the Indonesian archipelago, but especially in Java, Sumatra, Sulawesi, and portions of Bali.
Elevation: In Indonesia, robusta beans are usually grown between 600 and 1,400 meters above sea level.
2. Type of Bean:
Variety Coffee canephora, or robusta
Processing Method: Wet Processed (Washed): To produce a cleaner cup with less earthiness, the beans are washed to remove the cherry layer.
Dry Processed (Natural): When beans are dried while the cherry is still present, the flavor becomes more nuanced.
Defects: High-quality Indonesian Robusta beans usually have fewer than 5% flaws.
3. Size of Beans:
Screen Size: Usually 16/18 or 18/20, this indicates medium-sized to large beans.
Robusta beans are round and dense, with a slightly smaller size than Arabica beans.
4. Profile of Flavor:
Taste: Robusta beans from Indonesia are renowned for having a strong, earthy flavor that is distinctly bitter. They typically produce a strong cup of coffee with a full-bodied flavor.
Notes: The flavor is frequently characterized as spicy, woodsy, and with undertones of chocolate, nutty, and tobacco. Additionally, some Robusta beans from Indonesia have a faint herbal or smoky flavor.
Acidity: Robusta beans have a low acidity, which makes them taste fuller and smoother.
5. Caffeine Content: The caffeine content of robusta beans is typically 2.2% to 2.7% by weight, which is roughly twice that of Arabica beans. This increases the coffee’s intensity and kick.
6. Look:

Shape: Compared to Arabica beans, beans are typically rounder and smaller.
Surface: Because Indonesian Robusta beans contain less oil than Arabica, they appear matte and lifeless.
