Coffee Varieties of Central Kenya

Variety	Characteristics
SL28	Released by Scott Agricultural Laboratories (SAL) in 1930s–40s. Deep root structure maximizing scarce water resources; high yields; complex cup profile with bright acidity and berry notes
SL34	Also released by SAL. Similar to SL28 but with heavier body; deep root system; thrives without irrigation
Ruiru 11	Introduced by Kenya Coffee Research Institute. Disease-resistant (CBD and CLR); high yields; early maturity—cropping after only 2 years
Batian	Released by CRI in 2010. Named after Mount Kenya’s highest peak; resistant to CBD and CLR; early maturity—cropping after 2 years

Processing Excellence

Central Kenya is synonymous with fully washed processing, a meticulous method that enhances clarity and complexity:

1. Selective handpicking of only ripe cherries

2. Cherry sorting at intake—under- and over-ripes removed by dedicated cherry clerks

3. Pulping using disk pulpers to remove outer skin

4. Fermentation for 12–24 hours to break down mucilage

5. Soaking for up to 24 hours—research shows this adds points to final cup scores

6. Drying on raised beds for 7–16 days, with frequent turning for even moisture

The Central Kenya Cup Profile
