Since its inception in 2012, World Coffee Research has worked to establish dozens of trial sites around the world testing both existing and new varieties in different environments, both on research stations and in farmers’ fields. Many of those sites are starting to produce mature harvests, meaning the trees are ready to be evaluated for performance in the field—and in the cup. In 2019, one trial site testing new variety candidates in Costa Rica produced its first production harvest. WCR invited 20 industry cuppers to give feedback on the coffees.

WCR is accelerating the creation of coffee varieties to meet the challenges of the 21st century through the launch of a new Latin American Breeding Hub in Honduras.

Until recently, very little was known about the diversity of Yemen’s coffees outside of anecdotes and observation. In 2014, WCR partnered with Dr. Al Hakimi of S’ana University to explore the diversity of Yemeni coffees as part of a larger analysis of arabica genetic diversity. The study, published in Nature Scientific Reports in January 2020, expanded our knowledge of Yemen coffee’s genetic diversity. A further study by C. Montagnon in 2021 adds to knowledge of Yemen’s genetic diversity.
