Batian was released by Kenya’s Coffee Research Institute in 2010, and it is named after the highest peak of Mount Kenya.
What it solves
Ruiru 11, released in 1985, gave Kenyan farms resistance to coffee berry disease and leaf rust — and it cups more mildly than the SL varieties it replaced, which cost Kenya part of its reputation.
Batian was bred to close that gap: the same resistance, cup quality much closer to SL28.
The results
Widely accepted as succeeding. Batian scores well in cupping and it is being planted on quality-focused farms that would previously have accepted the disease risk of SL28.
It also matures faster than Ruiru 11 and yields well.
The stature
Tall, unlike the compact Ruiru 11, which affects planting density and harvesting. Some farms prefer the compact habit despite the cup.
What is planted now
Kenyan farms commonly mix SL28, SL34, Ruiru 11 and Batian, hedging cup quality against disease risk. Bags increasingly list the mix.
Brewing it
Filter, light roast, hot water, fine grind — as with any Kenyan coffee.
