Rainfall: 1,100-1,600mm annually
Pattern: Bimodal distribution
Long rains: March-May (main crop flowering)
Short rains: October-November (fly crop)
Dry seasons: Critical for processing quality
Microclimate: Aberdare influence creates localized patterns
Consistency: Relatively reliable patterns support quality

Soil Composition¶

Type: Volcanic red nitisols, humic nitisols

Style Variation by Altitude¶

Higher elevation: Brighter, more fruit-forward
Mid elevation: Best balance of acidity and body
Lower elevation: Fuller body, softer acidity

Processing Methods¶

Washed Processing¶

Traditional Kenyan double fermentation method:

Harvesting: Selective picking of ripe cherries
Pulping: Evening pulping, within 8-12 hours of harvest
Fermentation 1: 16-24 hours dry fermentation
Intermediate wash: Remove initial mucilage layer
Fermentation 2: 12-24 hours in clean water
Final washing: Thorough washing, density grading
Soaking: 12-24 hour clean water soak
Drying: African raised beds, 10-14 days
Turning: Regular turning for even drying
Sorting: Hand-sorting to remove defects

Factory Standards: - Well-established processing traditions - Generally good water quality - Experienced factory managers - Quality-focused cooperative culture
