Research
One strain of Ethiopian Coffea arabica naturally contains very little caffeine. Maria Bernadete Silvarolla, a researcher of Instituto Agronomico de Campinas, published findings in the journal Nature about these strains of C. arabica plants. While beans of normal C. arabica plants contain 12 milligrams of caffeine per gram of dry mass, these newly found mutants contain only 0.76 milligrams of caffeine per gram, but with all the taste of normal coffee.
The conservation of the genetic variation of Coffea arabica relies on conserving healthy populations of wild coffee in the Afromontane rainforests of Ethiopia. Genetic research has shown coffee cultivation is threatening the genetic integrity of wild coffee because it exposes wild genotypes to cultivars.
