What is Robusta coffee?
Robusta coffee, known scientifically as Coffea canephora var. robusta, is a major coffee species. It’s a hardy plant, strong and packed with caffeine. It has much more caffeine than Arabica. Robusta beans deliver bolder, more intense flavors. You’ll find them in espresso blends and instant coffee.
