Jam-like sweetness, deep body
process: Traditional method: harvested cherries are sun-dried whole with pulp intact, then hulled to extract green beans.
tip: As cherry flesh dries, sugars absorb into the bean core, imparting rich natural wine aromas and full-bodied fruity sweetness.
Transparent clean cup, bright fruity acidity
process: Cherry pulp is mechanically removed immediately, then beans are fermented in water tanks to wash away mucilage before drying.
tip: Complete mucilage removal reduces juicy sweetness but eliminates fines and off-flavors, yielding exceptionally clean, high-grade acidity with lemon/citrus nuances.
Honey-like complex sweetness, soft acidity
process: Cherry skin is removed, but mucilage is partially or fully retained during drying.
tip: Classified by mucilage content and sun exposure: Yellow Honey (25%), Red Honey (50%), Black Honey (90%+). Achieves both washed clarity and natural richness.
Innovative cinnamon, banana, exotic complexity
process: Beans and cherries are sealed in oxygen-free stainless steel tanks, promoting anaerobic fermentation microbes.
tip: CO₂ injection and controlled enzyme activity produce intense, artificial-like aromas—wine, rum, tropical cinnamon—dominating the modern specialty scene.
Each processing method triggers completely different biochemical reactions and physical drying conditions inside the bean. Select a method to compare chemical profiles and flavor characteristics.

Acidity: Acidity Expression
Sweetness: Body Sweetness

Clean Cup: Clean Cup Transparency
Complexity: Flavor Complexity
Pectin-digesting enzymes activate in water fermentation tanks, completely dissolving mucilage. Removal of off-flavor-causing organics maximizes the bean's native bright, crisp acidity.
Drying: 8–12 days
Water Activity: 0.52–0.58 aw
Metabolites: Increased lactic acid ratio, high citric/malic acid retention, amino acid accumulation
Long drying with cherry pulp attached allows high-concentration sugars to diffuse through cell membranes into the bean. Simultaneous wild yeast and lactic acid fermentation creates rich saccharification and complex aromas.
Drying: 15–25 days
Water Activity: 0.54–0.60 aw
Metabolites: Sucrose diffusion into bean core, surge in ester compounds and volatile alcohols
Sucrose and organic acids in cherry mucilage slowly dry and concentrate on the surface before absorption. Positioned between washed brightness and natural oiliness/sweetness, with honey-like unique texture.
Drying: 12–20 days
Water Activity: 0.53–0.59 aw
Metabolites: Partial mucilage drying reaction, melanoidin precursor development via browning enzymes
In CO₂-saturated anaerobic chambers, lactic acid bacteria decompose glucose into lactic acid and ethanol, rapidly accumulating volatile ester compounds. Produces intense cinnamon, rum, and tropical aromas rarely seen in conventional coffee.
Drying: 15–30 days (with 24–72h anaerobic fermentation)
Water Activity: 0.55–0.61 aw
Metabolites: Abnormally high concentration of anaerobic fermentation products (acetic acid, ethyl acetate, exotic flavor esters)
