Robusta

Raw Robusta coffee beans, or green Robusta beans, come from the Coffea canephora plant and have distinct characteristics compared to Arabica beans. Here are some key points about raw Robusta beans:

Characteristics

• Color and Size: Raw Robusta beans are generally smaller and rounder than Arabica beans and have a more uniform light green color.
• Moisture Content: Like Arabica, they have a moisture content of around 10-12%.

Flavor Potential

• Flavor Profile: Unroasted Robusta beans have a more earthy, nutty, or woody taste, but the complex flavors typically emerge during roasting.
• Caffeine Content: Robusta beans contain about twice as much caffeine as Arabica, contributing to a stronger, more bitter flavor.

Storage

• Longevity: Raw Robusta beans can also be stored for a long time if kept in a cool, dry environment, similar to Arabica.

Uses

• Roasting: Raw Robusta beans are often blended with Arabica beans for espresso and instant coffee, adding body and crema.
• Home Roasting: While less common than Arabica, some coffee enthusiasts roast their own Robusta beans for unique flavor profiles.
