Understanding Washed Coffees (And Why We Love Them)

When it comes to discovering new coffees, processing method is one of the most powerful (and underrated) keys to flavour.

Among all the options, we keep coming back to washed coffees for their clarity, precision, and transparent expression of origin.

what is a washed coffee?

Washed coffee, sometimes referred to as wet processed, refers to a post-harvest method where the coffee cherry’s pulp and mucilage are removed before the beans are dried.

After picking, the cherries are pulped mechanically, and the sticky mucilage layer is broken down through fermentation in water tanks. Finally, the clean beans are washed again before drying.

This process is designed to highlight the coffee's inherent qualities, bringing out the best from the varietal, the terroir, and the work of the farmer (as opposed to the influence of the coffee fruit’s sugars).

how you know a washed bean

If you've ever looked closely at a raw (green) washed coffee bean, you might notice a small white line (often called the "silver skin" or "parchment scar") running down the centre cut. While all beans technically have this, it tends to appear cleaner and more pronounced in washed coffees because of the thorough removal of fruit residues.

After roasting, washed beans also tend to look slightly lighter and more uniform than naturally processed beans (which can appear patchier or more uneven due to the fruit sugars caramelising differently).

why do we love washed coffee?

At Bell Lane, our Head Roaster Niko is drawn to washed coffees for their clarity and honest expression of origin.

A well-executed washed coffee allows us to showcase the true character of a farm or micro-lot without distraction.

We often describe these coffees as "clean," "bright," and "structured." Think well-defined acidity, layered florals, and transparent sweetness—qualities prized by both roasters and filter-focused coffee drinkers.

In sourcing, we look for washed lots that really show off their origin. A washed Ethiopian might deliver jasmine and stone fruit notes with tea-like delicacy. A washed Kenyan might burst with blackcurrant and juicy citrus.

By celebrating these profiles, we can support producers who are meticulous about picking and processing, rewarding quality at every step of production.
