Kenya is a small coffee producer, accounting for just 1 percent of the world's annual crop, but roasters require these quality Arabica beans to blend them with coffee from other regions. Coffee is one of Kenya's main foreign exchange earners.
Production is expected to rise to 47,000 metric tonnes this crop year from 45,000 tonnes in the year ended September.
