Identity and reference
SL28 is a Arabica entry in the World Coffee Research variety catalog. The source below provides the breeder’s agronomic context and regional observations.
How to interpret the name
For an SL28-labelled lot, record the producer’s variety declaration alongside any mixed-variety information. A washed Kenyan lot and a naturally processed lot elsewhere are not interchangeable tasting references.
Buying and tasting
Ask for lot-level provenance, processing and roast information. Keep the cultivar declaration as supplied by the producer and note any uncertainty. Compare using the same brew method, water and serving temperature before attributing a difference to genetics.
Growing decisions
Use current local extension advice when choosing planting material. Climate, disease pressure and access to authentic seed or clones matter; a catalog entry is not a site-specific planting recommendation.
