The Donggu Coffee Factory, located near Meru town in Kenya’s Eastern Province, sits at around 1350 metres above sea level and works closely with the Nthibiri Cooperative Society, which includes roughly 1500 farming households. This setup helps maintain consistent quality from cherry to cup.

This ensures consistency in cherry quality and helps preserve the unique characteristics of the SL28 and SL34 varieties.

What Does the Donggu Coffee Process Involve?

The region’s high phosphorus soils also enhance the complexity of the cup.

On the cupping table, Donggu’s SL28 and SL34 offerings present a bright and complex profile. Dry aromas include berry, orange, and pickled kumquat. After brewing, wet aromas reveal milk candy, berry, cream, chocolate, and a rich oily texture reminiscent of fruit tea. The mouthfeel is described as delicate yet oily.
