Blanca Ligia Riascos
Blanca Ligia Riascos is a coffee producer in Buesaco, Nariño, Colombia. SEY’s March 2026 Cumbre release documents her producing a washed Gesha at 2,100 meters.
History
SEY identifies the Cumbre lot as the beginning of a new sourcing project in Nariño, a remote region the roaster had visited early in its sourcing work but found difficult to work in consistently.
