About This Coffee
Naiberi Estate, nestled in the highlands of Kenya’s Rift Valley, is owned by Philip Kiprop Sawe, who has produced coffee here since 2014. At 1,980 meters above sea level, the farm draws on rich red volcanic loam soils and abundant rainfall to create ideal growing conditions. The estate’s location offers a unique terroir that, combined with careful cultivation and processing, yields coffees with the unique flavor profiles that characterize this part of Western Kenya.
Cultivation
On his 10-acre Naiberi Estate, farmer Philip Kiprop Sawe carefully tends SL28 and Ruiru 11 trees. At 1,980 meters above sea level, his coffee grows in fertile volcanic soils, where the combination of altitude, rainfall and hands-on farm management shapes the character of his coffees.
Harvest & Post-Harvest
Ripe cherries are selectively handpicked and pulped at the estate. Cherry is hand sorted at intake, and damaged, overripe and underripe cherry is removed before pulping at the estate.
Parchment undergoes fermentation for 12–24 hours. After fermentation, parchment is washed in clean water from the Naiberi River before being delivered to dry on raised beds for 14–21 days depending on weather conditions. Parchment is turned frequently to ensure uniform drying and prevent defects. Once dried, the coffee is hulled, graded and prepared for sale.
About Ruiru 11
Ruiru 11, a hybrid of Catimor and SL cultivars, is both Coffee Berry Disease (CBD) and Coffee Leaf Rust (CLR) resistant. Plus, it can be planted at a much higher density than the SL varieties, making optimal use of small plots of land.
Ruiru 11 has slowly ‘taken root’ across most of Kenya’s coffee growing landscape. The only issues were that with a shallower root structure, many farmers found the plant less hardy in drought conditions, and the trees required a more intense feeding program. Over time, farmers have found that by grafting Ruiru-11 to SL varieties they could take advantage of SL trees’ expansive root system and still reap the increased yields and higher immunity to disease of Ruiru-11.
Due to the grafted Ruiru-11’s growing popularity, most farms in Kenya today, both big and small, have a mixture of Ruiru-11 and SL varieties. As SL trees age, many farmers are opting to turn more towards Ruiru-11 (or the grafting solution) thanks to its ease of use and higher resistance to diseases.

About SL28 & SL34
SL28 and SL34 were just two of the cultivars released by Scott Agricultural Laboratories (SAL) during the height of SAL’s research in Kenya in the 1930s and 1940s. They soon became the cultivars of choice for most growers due to their deep root structure that allows them to maximize scarce water resources and flourish even without irrigation. SL varieties also had higher yields than the French Bourbon rootstock that they replaced and were known to be somewhat more disease resistant.
While SL varieties are still highly sought after today, they’ve become less widely cultivated in Kenya due to their relatively low resistance to coffee leaf rust (CLR). Compared to more recent varieties, SL varieties are more susceptible to diseases and pests and require very specific altitudes and climates to flourish. However, that hasn’t stopped specialty-focused farmers, who, inspired by the flavors and popularity of SL varieties, have have spread the cultivation of SL varieties worldwide.
AB Grade
Kenyan coffees are classified by size. AB beans are those that are between screen size 15 and 18 meaning that beans are between 6 and 7 millimeters in size.
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.
