"Coffee farmers were asked to produce Arabica beans of highest quality following an uncertain world market.

This resulted in the selling in November of an important quantity of speciality brands, boosting earnings," regulator ARFIC said in its monthly report.

Projected good harvests by top global producers like Brazil, Vietnam and Colombia, could lead to a drop in coffee prices on global markets, the Burundian regulator said.

Coffee is the country's top foreign exchange earner and the commodity provides a livelihood for 800,000 smallholder farmers in a nation of 8 million people.
