Kenya | Gathaithi PB | Ruiru 11 & SL-28 | Washed

Region: Tetu, Nyeri 

Elevation: 1720 masl 

About: Gathaithi Coffee Factory sits on the fertile red volcanic soils of Nyeri, where cool temperatures, reliable rainfall and high elevation create ideal conditions for producing expressive Kenyan coffees. Most growers cultivate traditional SL28 and SL34 varieties, alongside smaller plantings of Ruiru 11 and Batian. 

This lot is a Peaberry (PB), a natural mutation where only a single rounded seed develops inside the coffee cherry instead of the usual two flat-sided beans. Peaberries are separated during milling by screen size and shape. Their rounded form allows heat to penetrate more evenly during roasting, often resulting in a remarkably consistent roast. Many coffee lovers value peaberries for their concentrated flavour and distinctive cup profile. 

The factory also supports producers beyond harvest by providing farm inputs on credit, cash advances and encouraging tree planting to improve shade and long-term farm resilience. It is a practical, quality-focused approach that continues to strengthen both the coffee and the community behind it.

Sourced from the Tetu region of Nyeri, Kenya, this Gathaithi PB lot showcases the distinct character of the Ruiru 11 varietal alongside SL-28. Washed coffees from this region are often celebrated for their vibrant acidity and complex, sparkling profiles, a result of meticulous processing methods that emphasize clarity and precision. By utilizing the washed method, the inherent qualities of the bean are highlighted, allowing the specific terroir of the 1720 masl landscape to take center stage.
