Arabica coffee cherries are typically harvested when they reach a deep red or purple hue and have
a firm, glossy appearance.
Harvest selectively, focusing on cherries that ripen uniformly to ensure a higher quality and
consistent flavor profile.
Opt for selective picking, where only ripe cherries are harvested by hand.
This method ensures the collection of the highest-quality beans.
In larger plantations, strip picking may be employed, where all cherries are harvested from a
branch regardless of ripeness.
While more efficient, it may result in a mix of ripe and unripe beans.
Post-Harvest Processing Options:
Dry Processing (Natural Method):
Allow harvested cherries to dry in the sun before extracting the beans.
This method imparts unique flavors but requires careful monitoring to prevent over-fermentation.
Wet Processing (Washed Method):
Remove the pulp from the cherries and ferment the beans in water to loosen the mucilage.
Wash and dry the beans, resulting in a cleaner, brighter cup of coffee.
Drying and Storing Coffee Beans:
Proper Drying Conditions:
Ensure thorough drying of processed beans to prevent mold and ensure a stable shelf life.
Drying can be done naturally in the sun or using mechanical dryers.
