Guinea is a small nation in West Africa that exclusively grows Robusta coffee and has a major Robusta-growing region: Macenta.
Macenta has been producing coffee since the 1800s, powering what was a formidable coffee-growing industry in the country until the 1960s. Though Robusta coffee is generally considered inferior to Arabica, Macenta-grown Robusta is among the more coveted Robusta beans in the world due to its smoother profile.
