About This Coffee
Thirururi Factory is run by Komothai Farmers Cooperative Society (FCS). The FCS’s 7,00+ members deliver cherry to the station. Members of Komothai FCS cultivate coffee in Kiambu, where the superb microclimate provides ideal conditions for cultivating dense, sweet cherry.
Cultivation
Farmers delivering to Thirururi cultivate primarily SL28, SL34, Batian and Ruiru 11 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.
Batian is a relatively new variety introduced by the Kenya Coffee Research Institute (CRI) in 2010. Batian is named after the highest peak on Mt. Kenya and is resistant to both CBD and CLR. The variety has the added benefit of early maturity – cropping after only two years. Similar to Batian, Ruiru 11 is a new variety known for its disease resistance and high yields. It also starts yielding fruit after just 2 years.
Harvest & Post-Harvest
Smallholders selectively handpick only ripe cherry and deliver it to Thirururi Factory. At intake, the Cherry Clerk oversees meticulous visual sorting and floating, accepting only dense, ripe cherry.
After intake, cherry is pulped and fermented for approximately 16 to 24 hours. Following fermentation, coffee is washed clean water. Then, parchment is laid to dry on raised beds. Workers rake parchment frequently to ensure even drying. They cover drying parchment during the hottest time of day, to maintain slow, even drying and at night, to shelter parchment from moisture. It takes approximately 14 to 18 days for parchment to dry.
AA Grade
Kenyan coffees are classified by size. AA beans are the largest size. AA grade coffees are those that are 17/18 screen size, meaning that they are larger than 7.2 millimeters.
About Kiambu
Kiambu is right outside Kenya’s capital city of Nairobi but is nonetheless known for agriculture – specifically coffee and tea. The county is also home of the Kenyan Coffee Research Foundation.
Kiambu County is also well known for its dairy production, and is the largest dairy producing county in Kenya. Many of the growers here adhere to organic fertilizing practices, using only cow manure instead of agrochemicals on their coffee trees.
Farmers in Kiambu face low production due to pests and disease while simultaneously having to pay high prices for inputs. In recent years, many have felt the strain and have sold their land to real-estate developers looking to build on the edge of Nairobi.
Coffee in Kenya
Though coffee growing had a relatively late start in Kenya, the industry has gained and maintained a impressive reputation. Since the start of production, Kenyan coffee has been recognized for its high-quality, meticulous preparation and exquisite flavors. Our in-country sister company, Sucafina Kenya, works with farmers across the country to ensure these exceptional coffees gain the accolades they deserve.
Today, more than 600,000 smallholders farming fewer than 5 acres compose 99% of the coffee farming population of Kenya. Their farms cover more than 75% of total coffee growing land and produce nearly 70% of the country’s coffee. These farmers are organized into hundreds of Farmer Cooperative Societies (FCS), all of which operate at least one factory. The remainder of annual production is grown and processed by small, medium and large land estates. Most of the larger estates have their own washing stations.
Most Kenyan coffees are fully washed and dried on raised beds. The country still upholds its reputation for high quality and attention to detail at its many washing stations. The best factories employ stringent sorting practices at cherry intake, and many of them have had the same management staff in place for years.
