Lampung Robusta for Espresso Blends: A Roaster's Sourcing Guide
Published June 2026 · By Willkin Green Coffee (PT Global Wills Sejahtera)
Lampung Robusta (Coffea canephora) from South Sumatra is one of the most widely exported Indonesian coffees, used globally in espresso blends, instant coffee, and capsule formats. This guide is written for commercial roasters and blend developers who want to understand how Lampung Robusta performs and how to source it responsibly.
Why Robusta in Espresso Blends?
Robusta contributes three things that Arabica cannot fully replicate at comparable cost:
Crema: Robusta produces ~30–40% more crema than Arabica due to higher CO₂ retention and different lipid profile
Caffeine: Robusta contains ~2.7% caffeine vs ~1.5% in Arabica — increases perceived strength and energy delivery
Body: Full, thick mouthfeel that stabilizes espresso texture under milk
Cost: Typically 40–60% cheaper per kg than comparable-volume Arabica
