Batian Coffee

Batian exists because Ruiru 11 was only half the answer. Coffee berry disease and leaf rust had already forced Kenya’s Coffee Research Station at Ruiru to breed one disease-resistant variety in 1985, but Ruiru 11’s cup never fully shed the reputation of tasting flatter than the SL varieties it was meant to replace. The station’s next attempt, released on September 8, 2010 according to Perfect Daily Grind’s reporting, took a fifth-generation single-tree selection out of the Ruiru 11 breeding program and backcrossed it more heavily toward SL28 and SL34, aiming to close the flavor gap without giving up disease resistance. Named for the highest peak on Mount Kenya, Batian carries the same wide genetic base as its predecessor, SL28, SL34, Rume Sudan, N39, K7, SL4, and the Timor Hybrid, per World Coffee Research’s variety profile, which also credits it with resistance to coffee berry disease and intermediate resistance to leaf rust.

The agronomics read like a farmer’s wish list. Trabocca’s overview of Kenyan varieties describes Batian’s very large beans and tall trees fruiting in as little as a year and a half, versus the longer wait for a mature SL tree, at a planting density of roughly 1,900 trees per hectare. CRI director Dr. Elijah Gichuru told Perfect Daily Grind that the reduced spraying this resistance allows can cut production costs by up to 30%, and more than 100,000 seedlings went out to farmers through Nguzo Africa starting in 2015. Demand for planting material has outpaced the nurseries ever since.

Whether the cup lives up to the agronomics is the part still being argued lot by lot. Kenyan authorities have pointed to comparative cuppings where Batian outscored SL28, though critics note those trials have sometimes used underwhelming SL28 samples as the baseline. Coffee Review’s own October 2020 Kenya report took a more cautious middle path: the few samples it has cupped claiming to be pure Batian kept the variety’s savory depth but not SL28’s juicy sweet-brightness, and the magazine admits judging the variety is “difficult to assess at this point and at this distance,” since almost nobody sells it alone. Most Kenyan smallholder plots and cooperative factories interplant Batian with SL28, SL34, and Ruiru 11, and the bag names all of them.

That blending is exactly what shows up in the three real, scored lots behind this entry’s flavor profile. JBC Coffee Roasters’ Giakanja Kenya and Ngomano Kenya, and Equator Coffees’ Kenya Wachuri, each named Batian as one variety among three or four on the label, scoring 94, 93, and 95 points respectively, with pomegranate, red currant, and Concord grape notes running through syrupy, winey cups. None of them isolates what Batian alone contributes, but together they are the best real evidence of what the variety tastes like doing the job it was actually bred for: holding its own, in a blend, in a Kenyan farmer’s field.
