Halu Beriti Washing Station was established in 2014 and serves 750 smallholder producers, who deliver their coffee in cherry form. For this special preparation Washed lot, the coffee is meticulously sorted with more attention during the entire process, from delivery throughout the drying period. The seeds are picked through as they dry on the raised beds to remove any that are drying unevenly or that show sign of mill or insect damage, for instance.

After delivery to the washing station, it is depulped and undergoes a fermentation time of 48–72 hours. It is washed clean, then soaked for 8–16 hours, then washed one more time before being dried on raised beds for 9–12 days. This is a special-preparation lot, which means it underwent significantly more meticulous sorting throughout the processing and drying times.

Coffees in Ethiopia are typically traceable to the washing station level, where smallholder farmers—many of whom own less than 1/2 hectare of land, and as little as 1/8 hectare on average—deliver cherry by weight to receive payment at a market rate. The coffee is sorted and processed into lots without retaining information about whose coffee harvest is in which bag or which lot.
