Intro

This is our first year working with the Kirimahiga AB lot, and it delivers everything we love about classic Kenyan coffee. Bright, juicy, and expressive, this coffee showcases vibrant stone fruit acidity, sparkling citrus, and elegant florals—an excellent introduction to Murang’a’s dynamic cup profiles.

The Producer

Kirimahiga Factory is one of three standout washing stations that make up the New Kiriti Farmers Cooperative Society (FCS). Established in 1988, the cooperative brings together generations of smallholder farmers united by a shared focus on quality and consistency.

Today, Kirimahiga serves 1,595 registered farmers, most of whom cultivate coffee on small family plots. Their collective experience, combined with centralized processing and quality control, allows Kirimahiga to produce coffees that consistently represent the best of the region.

The Process

Ripe cherries are carefully selected and de-pulped using a disc pulping machine to remove the skin and fruit. After pulping, the coffee is graded and fermented for 16–24 hours, allowing acidity and sweetness to develop.

Once fermentation is complete, the parchment is thoroughly washed and passed through grading channels before undergoing a second soaking stage in fresh stream water for 16–18 hours. Finally, the coffee is sun-dried on raised beds for up to 21 days, ensuring even drying and excellent clarity in the cup.

In the Cup


The cup is bright, juicy, and refreshing. Zesty lime and tangerine acidity leads the profile, followed by a layered sweetness reminiscent of pomegranate and blackberry. As it cools, delicate florals lift the finish, adding elegance and balance. The result is a vibrant Kenyan coffee with lively acidity, clear structure, and a clean, lingering finish.

What is the roast recency?

September doesn't generally advertise a roast preference to Filter or Espresso, however, this is an exception and this particular bag is best enjoyed as espresso!

We recommend brewing with beans that are at least two weeks off roast. All beans are roasted to peak flavour at around 8-12 weeks. We have the option to either purchase standard beans (at least 2 weeks but no longer than 6 weeks off roast), or rested beans (at least 7 weeks off roast, no longer than 12). For peak flavour, if you are looking to use immediately, we recommend purchasing the rested beans. If you are adding to your rotation of beans, we recommend purchasing the standard and allowing the beans to naturally rest and mature whilst you rotate through other beans.
