Arsosala is a washing station founded in 2015 that currently serves about 1,200 smallholder producers in the Urga woreda of Guji. Coffees are picked ripe and dried on raised beds. It typically takes 8–15 days to dry under sun and 15–20 days to dry when there are cloudy skies.

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.
