The Rianjagi Farmer's Cooperative Society represents more than 2,500 local farmers whose plots average under a quarter hectare. Rockbern Coffee, founded by third-generation producer Peter Muchiri, facilitated export; it is not the grower.
Partners Coffee identifies this as its first Kenyan offering in several years and its first purchase through Rockbern Coffee.
A current, highly traceable Embu cooperative release with a clearly documented single-fermentation washed process and four-variety field composition.
WHAT DID THEY ACTUALLY
DO TO THIS COFFEE?
Members deliver ripe cherry to Rianjagi Factory, where it is depulped the same evening.
Depulped coffee ferments without water for up to 24 hours.
Workers agitate the coffee in elongated channels to remove mucilage and sort it by density.
Parchment dries slowly on raised mesh platforms protected by shade netting.
No fruit, culture or flavoring is disclosed.
No co-ferment ingredient, inoculated culture or post-roast flavoring is reported.
The single-fermentation washed method preserves clarity while channel sorting separates denser coffee.
Blackberry, clementine, pomegranate, golden raisin, molasses and ginger.

In the database. Not tasted. Not scored.
This coffee is in our database because we can reliably document it — but we haven't tasted and scored it yet, and we never publish a score we haven't earned.
Outside reviews and internet discussion — is kept clearly separate from our own review. When we taste it, our full review appears here.
What the internet is saying about this coffee
Our research pipeline scanned public reviews, videos, forums and discussions for this coffee (last pass 2026-10-25) and found no independent review of this exact release that meets our verification standards. When qualifying sources appear, they'll be published here.
Non-exact, seller, directory, generic-roaster, different-release, duplicate, and older-release sources were excluded.

Other roasters, same producer.
These coffees come from the same producer or farm, offered by other roasters. We never automatically declare two offerings the exact same coffee — a match requires lot, harvest and traceability details. Even a true same-lot pair can taste different: roast approach, freshness, rest and brewing all reshape the cup.
