Coffea canephora
E tier
Coffea canephora is the diploid coffee species commercially known as robusta, native to the lowland forests of West and Central Africa. Trees are more vigorous and heat- and disease-tolerant than arabica, with higher caffeine content in the seed, smaller rounder beans in many selections, and adaptation to lower altitudes and harsher climates. Cup profile is typically fuller-bodied, more bitter and earthy or woody, with lower perceived acidity and strong crema contribution in espresso. Canephora underpins soluble coffee, many espresso blends, Vietnamese and other regional styles, and cost-effective industrial supply, while select fine robustas are increasingly treated as specialty lots.

History
Wild canephora populations in the Congo basin and West Africa were known to local communities long before export agriculture.
Belgian colonial collections from the Congo popularised canephora for plantation trials outside Africa.
After leaf rust hit arabica, Java and other Asian islands expanded canephora as a hardier crop.
Brazil and other producers adopted canephora for lower elevations and industrial demand.
Instant coffee and espresso-blend economics made canephora a large share of global green coffee volume.
Fine robusta programmes began to reframe high-quality canephora for specialty cupping and marketing.
