  „This means coffee pickers are usually working at the trees during the day and delivering to the mill or receiving stations in the evening. The coffee cherries are tipped into large tanks of water where the first separation of quality occurs: FLOATERS The cherries which float are empty or immature and do not yield high quality coffee. SINKERS The cherries which sink are excellent and ripe, perfect for processing into high quality coffee Our mill works on a binary system which processes the sinkers along a totally different path than the floaters. The cherries are then passed through a pulping machine which squishes out two coffee seeds.“

Ten Steps To Coffee - National Coffee Association

  „Pickers rotate among the trees every 8 - 10 days, choosing only the cherries which are at the peak of ripeness. Because this kind of harvest is labor intensive, and thus more costly, it is used primarily to harvest the finer arabica beans. “

Processing Coffee

  „The first stage of pulping is used to remove the green cherries from the ripe cherries.  In the pulping machine the internal pressure is monitored to push the coffee against a screen with holes only large enough for a coffee bean (not cherry) to pass through.  Since the ripe cherries are soft they break and the seed is released through the screen.  Video showing pulping machine and pulp separating barrel medium (5.6 Mb) or small (1.5 Mb).  “

  „It was also found that there was little infection of coffee cherries while on the tree but infection occurred postharvest, the most likely sources being soil, equipment and drying yard surfaces. Improvements in good agricultural practices have reduced ochratoxin A contamination of coffee.“

Coffee Growing at Home

  „If coffee cherries are not readily available, green coffee can be purchased from a local supplier, but it is essential that the bean is of a recent crop and recent shipment.  I would recommend ordering green coffee from Sweet Maria's and asking for the most recent crop.  The potential for germination will continue for almost four months, but after this time the germination rate is several fold less and germination time is significantly longer.  Fresh seeds should germinate in 2.5 months, but old seeds can take as long as 6 months. Coffee in pergamino is even better. If this is available plant the coffee face down in the pergamino.“
