How Coffee Beans are Processed

See How It's Done

Ever wondered how coffee beans go from cherries into your cup? Here's how it works:

  • Coffee plants are cultivated from Kona Arabica seedlings; a plant may produce for a hundred years or more
  • It takes seven or more months for fruit to grow to ripeness after the plant flowers
  • The coffee cherries are picked when ripe; ripeness is determined by color (a deep red) as well as via a scientific instrument that measures the sugar content
  • If cherries are allowed to get too ripe, they start fermenting and dry out
  • Once picked, a machine rinses the cherries
  • Another machine then squeezes the cherries, so that the bean is extracted; the skin and pulp are then used as fertilizer on the coffee plants
  • Beans must be processed the same day they are extracted, or they begin to ferment
  • The beans go through another machine to separate the parchment layer of skin from the hard bean (Fabio said, “The coffee bean is like a peanut with two layers of skin. The parchment is a protection to keep the bean from being damaged.”)
  • The beans are dried, a process that takes about 30 hours
  • The beans are sorted by size and density; the larger/heavier coffee beans have richer flavor and aroma because they have more nutrients and sugar content
  • After they are processed, the beans go into a temperature- and humidity-controlled room to prevent mold, which would change the flavor, while they wait for certification as Kona beans
  • Once the beans are certified, they are roasted and hand-packed daily for sale
