Processing Methods¶

Washed Processing (Traditional & Common)¶

Tarrazú excels in washed processing:

Selective picking: Multiple passes, only ripe
Pulping: Within 6-12 hours of harvest
Fermentation: 12-24 hours, carefully monitored
Washing: Clean mountain water, multiple rinses
Drying: Raised beds or patios, 10-14 days
Sorting: Meticulous hand-sorting
Result: Crystalline clarity, explosive acidity

Water Sources: - Mountain streams - Clean, mineral-rich - Abundant during processing season

Honey Processing (Growing)¶

Increasing adoption for market diversity:

Red Honey (Most Common): - 50% mucilage retained - Enhanced sweetness and body - Maintains Tarrazú brightness - Popular in specialty market

Black Honey: - 100% mucilage retained - Full body, intense sweetness - Balanced acidity - Requires excellent drying infrastructure

Yellow Honey: - 25% mucilage - Subtle sweetness enhancement - Closest to washed

Natural Processing (Experimental)¶

Very limited due to historical restrictions: - Recent legalization - Requires controlled environment - Experimental lots emerging - Challenges cup character perception

Farming Practices¶

Farm Structure¶

Size: 3-15 hectares typical
Family farms: Multi-generational ownership
Steep slopes: Hand-harvesting essential
Terracing: Common on steepest areas
Processing: Mix of cooperative and micro-mill
Organization: Strong cooperative tradition, growing micro-mills

SL-28: Limited trials, promising results
Bourbon: Rare, heritage plots

Cultivation Methods¶

Shade: Moderate shade from mixed species
Shade trees: Ingas (nitrogen-fixing), fruit trees
Organic practices: Many farms organic by default or certified
Fertilization: Moderate NPK applications
Pruning: Regular cycles for tree health
Pest management: Integrated approaches
Selective harvesting: 3-5 passes essential for quality
