Variety:
This lot from Nthimbiri consists of a blend of SL28, SL34, Ruiru 11, and Batian—four cornerstone cultivars in Kenya’s coffee landscape, each contributing distinct strengths to the cup.
SL 28: SL 28 was selected in the 1930s by Scott Agricultural Laboratories for its exceptional drought resistance and cup quality. It is known for producing coffees with bright, wine-like acidity, layered sweetness, and notable clarity. SL28’s genetic lineage traces back to the Bourbon-Typica group, and it remains one of the most prized varieties in East African specialty coffee.

SL 34: Another selection from Scott Labs, was developed from French Mission Bourbon and is well-suited to high elevations with good rainfall. It produces excellent cup profiles—often with a bit more body than SL28—though it is more susceptible to disease. Together, SL28 and SL34 form the traditional backbone of many of Kenya’s top cooperative lots.

Ruiru 11: Ruiru 11 was released in 1985 by Kenya’s Coffee Research Foundation in response to widespread disease pressure. It is a compact, high-yielding hybrid that combines the cup traits of SL28 with the disease resistance of Catimor. While Ruiru 11 has historically received mixed reception for cup quality, careful separation and processing can result in expressive, fruit-forward coffees as we can see in Kenya and Rwanda offering where they are featured quite often.

Batian: Batian is a newer hybrid introduced in 2010, bred for resistance to Coffee Berry Disease and Leaf Rust, as well as early maturity and high yield. It includes genetics from SL28 and SL34 as well as Timor Hybrid, K7, and other selections. While still gaining ground among producers, Batian shows strong potential for clean, sweet cups when grown and processed carefully.
