Decaf Robusta: Decaffeination Process, Quality, and Applications
Decaf robusta is green robusta coffee with most of its caffeine removed before roasting, typically to 0.1% or less (dry basis) for European buyers. Because robusta starts with roughly twice the caffeine of arabica, decaffeinating it is harder work, but the result keeps the body and crema that make robusta useful in espresso blends and instant coffee.
