Kenya - Rui Ruiru AA Natural Anaerobic

Rui Ruiru Factory is a Kenyan producer nestled in the fertile slopes of Mathira, Nyeri County, where it works alongside local smallholder farmers whose high-elevation coffee plots give the region its bright and expressive character.

For years, Rui Ruiru was celebrated for producing exceptional coffee under the Mathira North Cooperative. But after the group ceased operations in 2014, the factory gradually fell into disrepair. Still, the community refused to let its story end there.

In 2020, representatives of Rui Ruiru Station, led by village headman Charles Maina and supported by the Ministry of Agriculture and the Nyeri County Government, partnered with Crowd Farm Africa to restore the factory and bring production back to life.

Since then, Rui Ruiru has embraced carefully crafted natural and anaerobic processing methods, combining modern experimentation with the traditions that define Kenyan coffee. The result is a new chapter for the factory — one rooted in resilience, innovation, and the people who continue to shape its future.

Rui Ruiru Coffee Factory focuses on Kenya’s celebrated SL varieties — particularly SL28 and SL34 — cultivars developed by Scott Agricultural Laboratories to withstand coffee leaf rust and berry disease while preserving exceptional cup quality.

Working closely with local smallholder farmers, the factory carefully hand-harvests ripe cherries before guiding them through meticulous natural and anaerobic processing methods designed to intensify sweetness and fruit expression.

For their natural coffees, whole cherries are dried slowly with minimal water usage, allowing sugars and fruit compounds to develop deeper complexity over time. Rui Ruiru’s anaerobic lots push this expression further, using sealed fermentation techniques to create layered cups with vivid fruit tones, vibrant acidity, and refined sweetness.

After fermentation, the coffees are carefully dried on raised African beds to ensure even airflow and gradual moisture reduction. This preserves the bright character that defines exceptional Kenyan coffee.
