Washing Station Manager

The washing station manager is a critical link in the coffee supply chain, particularly in regions that utilize the washed process. This individual oversees the daily operations of a wet mill, where harvested coffee cherries are transformed into parchment coffee. Their responsibilities are vast, ranging from managing the intake of cherries from local smallholder farmers to monitoring the precise timing of fermentation tanks and the drying process on raised beds.

What is a washing station manager's role? The manager must ensure that the coffee is processed according to strict quality standards. This involves sorting cherries for ripeness, managing water usage, and ensuring that fermentation is stopped at the exact moment to avoid defects like over-fermentation or the 'potato defect.' They are essentially the quality control gatekeepers at the origin, as their decisions directly impact the final cup profile of the coffee.

Why does this role matter? The quality of a coffee is largely determined at the washing station. Even the best-grown coffee can be ruined by poor processing. A skilled manager ensures that the coffee is dried to the correct moisture content, which is essential for the stability of the green bean during shipping and storage. They also manage the logistics of the station, ensuring that different lots are kept separate to maintain traceability, which is a cornerstone of specialty coffee.

In practice, the washing station manager is often the person who interacts most directly with the farmers. They provide feedback on cherry quality and often coordinate payments based on the quality of the harvest. For a roaster or importer, the manager is a key partner in ensuring that the coffee they receive matches the expectations set during the buying process. Their work is the difference between a mediocre commodity coffee and a high-scoring specialty lot.
