Washed Coffee Bean Process Introduction and Flavor Profile of Colombia Washed Geisha Pour-Over

FrontStreet Coffee - Colombian Washed Coffee and Wash Processing Steps

1. Depulping

Specialized equipment removes the skin and part of the pulp from the cherry. After this step, some pulp and mucilage still cling to the parchment.

2. Fermentation

The parchment coffee, still coated in pulp and mucilage, is soaked in water so the mucilage ferments; once fermented, it rinses off easily. Fermentation takes about 24 hours.

3. Washing

The fermented parchment coffee is washed in flowing water channels to strip off the pulp and mucilage. In practice, some producers soak the washed beans again in clean pools for 3-6 hours to develop new flavors.

4. Drying

The parchment beans are spread on drying patios, sometimes finished in mechanical dryers. At 12% moisture they can be warehoused. Beans stored in parchment keep longer than hulled beans.

Once moisture is reliably brought down to 12.5%, the beans are stored pending export. Just before export, machines remove the dry parchment and the final layer of silver skin; then come cleaning, screening, sorting, grading, and packaging.

Washed coffee offers a cleaner taste free of off-flavors, with charming fruit aromas. Washed beans tend toward blue-green or gray-green in color. The cup is clearer, more vibrant, and without defects.

FrontStreet Coffee Recommendation

Geisha comes in more forms than most people realize. Panama made the variety famous: the high altitude, microclimates, and soils there produced such striking coffee that when the Esmeralda estate entered it in the 2003 Best of Panama competition, the judges were stunned—an average cupping score of 94.6 broke the competition record, and Geisha became an overnight sensation.

FrontStreet Coffee's Esmeralda Red Label Geisha (Esmeralda Special) grows at 1,600-1,800 meters and must cup above 90 points per batch, with each batch traced to a single plot; the Green Label (Private Collection) mixes batches across plots for the estate's signature style at a better price. For an accessible first taste, the Panama Boquete Geisha delivers classic orange-blossom honey notes, oolong-tea texture, and delicate fruit sweetness.

Back at the variety's birthplace, Ethiopia's Geisha Village estate—founded by a couple 12 miles from the Geisha forest on 475 hectares—selects the strains closest to Panama Geisha by plant morphology, bean shape, and cupping. For brewing any of these, FrontStreet Coffee suggests a medium-light roast, a grind at 78% pass through China's #20 sieve, 91°C water, and a three-pour V60 method: 30g bloom for 30 seconds, then to 125g, then to 225g, finishing in about 2:10-2:20.
