From Cherry to Green Bean

Coffee Farm Hawaii

Q: How does this coffee farm in Hawaii process every lot from cherry to green bean?

Every step from picking through drying happens on this property at 84-4956 Hawaii Belt Rd in Captain Cook, no co-op mill or shared processing facility.

Q: How does the harvest process affect the final cup quality?

Selective picking ensures only ripe cherries enter the process. Same-day pulping prevents degradation. Raised-bed drying produces even moisture and fewer defects.

Q: What grades come out of the harvest process?

Extra Fancy (Screen 19+), Fancy (Screen 18+), No.1 (Screen 16+), and Peaberry. All graded to Hawaii state standards.

Q: When is the harvest season at Kona Volcano Farm?

Primary harvest runs August through January, peaking in October and November. Contact us early to secure your lot.

Q: Can I see the harvest process in person?

Yes. Farm visits by appointment for wholesale buyers and roasters. Call 808-315-9021 or email sales@konavolcano.com to schedule.

Six steps on a single estate, from hand-picked cherry to a Hawaii state-certified green bean. Every step stays on one property.

The Process

Six Steps from Cherry to Certified Green Bean

Quality in the cup starts long before roasting. At Kona Volcano Farm, every step of the harvest process happens on one property, under direct oversight, with documentation that follows each lot from picking to shipment.

Selective Hand-Picking

Every cherry on this farm is picked by hand at peak ripeness. Pickers move through the rows multiple times per season, selecting only the fully red cherries. Green, yellow, or overripe fruit stays on the tree. This selective picking directly determines what grade the green beans can reach after processing.

Same-Day Pulping

Cherries are pulped within hours of picking on-site. Delaying this step degrades quality. The pulping machine removes the outer fruit layer, revealing the sticky, mucilage-coated parchment surrounding the green bean.

Fermentation & Washing

Parchment coffee ferments in water for 12 to 24 hours to loosen the remaining mucilage. After fermentation, the beans are washed thoroughly with clean water. Everything happens on this property, not at a shared co-op facility.

Raised-Bed Drying

Washed parchment dries on raised drying beds, where airflow circulates around the beans on all sides. This reduces defects and produces more even moisture distribution compared to patio or mechanical drying.

Hulling & Sorting

Dried parchment is hulled to remove the outer layer, then sorted by size and density. Extra Fancy comes in at screen 19+. Fancy at 18+. No.1 at 16+. Peaberry is sorted separately by its distinct round shape.

Defect Count & State Certification

Every lot is defect-counted per Hawaii state standards and assigned its official grade. A lot number, harvest date, processing batch, and Hawaii state certification are documented before any beans leave the farm.

Why It Matters

On-Site Processing Is the Difference

Most farms in Hawaii send their cherries to a shared co-op mill for processing. That means your beans traveled through a facility that handled cherries from many different farms, at different ripeness levels, with different growing histories. By the time those beans reach you, the origin story is blurry.

At Kona Volcano Farm, cherries picked today are pulped today on the same property. The fermentation tank, the drying beds, the hulling equipment, all of it is on-site. Every bean that leaves this farm came from cherries that stayed in one place from tree to shipment bag.

Real lot-level traceability means the cherries in your lot never touched another farm's processing equipment. The lot number on your shipment ties to a specific picking date, a fermentation batch, and a drying cycle. All verifiable because it all happened in one place.
