Coffee & Quality
Quality begins on the farm and is protected at every step.
From selecting ripe cherry to clean wet processing and careful drying, every decision helps protect the character and value of Kibirigwi coffee.
Shared responsibility
Good coffee cannot be repaired after quality is lost.
Quality starts with healthy trees and careful harvesting. It continues through clean reception, accurate weighing, pulping, fermentation, washing, drying, storage, milling, and marketing.
Kenya's Coffee Directorate identifies uniformly ripe cherry and processing within 24 hours as the first steps in quality control.
At harvest and delivery
What every farmer can do to protect quality.
Small choices during picking and transport can affect the entire factory lot. Use this checklist each picking day.
Check the latest picking-day noticePick only ripe red cherry
Return for green cherry later instead of mixing immature fruit into the delivery.
Use clean containers
Keep cherry free from soil, chemicals, fuel, fertiliser, and other sources of contamination.
Sort before delivery
Remove leaves, twigs, stones, damaged fruit, overripe cherry, and other foreign matter.
Do not collect fallen cherry
Keep ground-picked fruit separate because it carries a higher contamination and mould risk.
Deliver without delay
Take fresh cherry to the designated factory promptly and follow the official receiving schedule.
Check your record
Confirm member details and recorded weight, then keep the issued delivery record.
The quality window
Fresh, uniformly ripe cherry should be processed within 24 hours.
Delays can encourage unwanted fermentation and make it harder to preserve a clean, consistent cup.
Fully washed process
How quality is protected at the factory.
Kibirigwi's published coffee profile identifies fully washed processing across the society.
Receive & sort
Cherry is checked at intake so unsuitable fruit and foreign matter can be separated.
Weigh & record
Deliveries are measured and recorded to support traceability and farmer records.
Pulp
The outer fruit is removed from ripe cherry while the beans remain protected by parchment.
Ferment & wash
Controlled fermentation and clean washing remove remaining mucilage from the parchment.
Grade & dry
Parchment is separated by density and dried evenly with protection from contamination and re-wetting.
Store & mill
Dried parchment is weighed, safely held, and prepared for dry milling into green coffee.
Protect the lot
Common quality risks to avoid.
Immature fruit can reduce sweetness and create uneven cup quality.
Old or ground-picked cherry increases fermentation, mould, and contamination risk.
Soil, leaves, chemicals, dirty water, sacks, or containers can taint an entire lot.
Fresh cherry left too long before pulping can develop unwanted flavours.
Thick layers, poor turning, and rain re-wetting make moisture inconsistent.
Moisture, odours, pests, and direct floor contact can damage dry parchment.
Understanding grades
Grade and cup quality are related—but they are not the same thing.
Primary wet processing separates parchment by density. During dry milling, Kenyan coffee is further graded mainly by bean size, shape, and density.
Parchment gradesP1 · P2 · P3 · PL
Common clean-coffee gradesE · AA · AB · PB · C · TT · T
Final quality and value also depend on cleanliness, defects, moisture, roast behaviour, and cup evaluation—not size alone.
Kibirigwi quality investment
Infrastructure and farmer training support better coffee.
Fairtrade Africa's 2022 producer profile documents 78 metal drying beds introduced to improve drying and protect parchment quality. It also records farmer training in good agricultural practices and Fairtrade production standards, alongside manure support intended to improve quality and productivity.
