Washing Station Manager

What is a washing station manager? They are the technical experts responsible for the transformation of coffee cherries into parchment coffee [4]. This role is one of the most high-pressure positions in the supply chain, as the decisions made at the washing station—from fermentation times to drying speeds—directly dictate the final quality and value of the coffee [5].

During the harvest, the washing station manager oversees a team of workers who sort, depulp, ferment, and wash the coffee [7]. They must monitor variables like water quality, fermentation tank pH, and ambient temperature to ensure consistency across every batch [5]. A single mistake, such as over-fermentation or uneven drying, can result in defects that significantly lower the coffee's grade and price [5].

Beyond the technical aspects, the manager is responsible for the station's logistics and environmental impact [5]. They must manage the flow of cherries from hundreds of farmers, ensuring that each lot is tracked and separated correctly [7]. They also oversee the management of wastewater, a critical issue in many coffee-growing regions, ensuring that the station complies with local environmental regulations [5].

In practice, the washing station manager is the guardian of the coffee's flavor [5]. Their ability to execute a specific process—whether it is a traditional washed process or an experimental anaerobic fermentation—is what allows a coffee to express its unique terroir [5]. For roasters, the manager's expertise is the difference between a standard commercial lot and a high-scoring specialty micro-lot [5].
