Farmers delivering to Cheriwet cultivate primarily SL28, SL34, Ruiru 11 and Blue Mountain in small coffee gardens that are, on average, smaller than 1 hectare. ‘SL’ varieties are cultivars originally released by Scott Agricultural Laboratories (SAL) in the 1930s and 1940s. They soon became the go-to trees for many growers in Kenya due to their deep root structure, which allows them to maximize scarce water resources and flourish even without irrigation. They are cultivated with a serious eye to sustainability and Good Agricultural Practices, with minimal environmental impact where possible. Ruiru 11 is a newer variety known for its disease resistance and high yields. It starts yielding fruit after just 2 years. Blue Mountain is a Typica mutation that was first found and cultivated in Jamaica’s Blue Mountains. The variety is also widely cultivated in Hawaii, on Kona Island, where it is typically called “Guatemala.” The variety was also introduced to East Africa in 1894 through Malawi and Rwanda and to West Kenya in 1913. Today it is mainly grown in Hawaii, Jamaica, West Kenya, Rwanda and PNG. Like its Typica ancestor, Blue Mountain does well at high altitudes. It’s also resistant to Coffee Berry Disease (CBD).
