Coffee harvesting is labor intensive and seasonal. Farms with
trees producing coffee cherries at various stages of maturation
use a method of harvesting called selective picking. Selective
picking calls for pickers to walk with baskets or bags slung
over their shoulders or hips allowing both hands to remain
free to pick only the ripe cherries from individual branches
as they walk among the trees. During the harvest season, selective
picking occurs every 8 to 10 days. A picker can harvest between
100 to 200 pounds of cherries per day. Due to dehydration
only 20% of this harvested weight results in actual green
bean weight.
Factoid:
One Arabica coffee tree annually yields about 1 to 1 1/2
pounds of roasted coffee.
In areas with a highly defined seasonal rainfall and
subsequent simultaneous ripening of all the trees' fruits,
a method called strip picking is used to harvest. With this
method, a tarp is placed on the ground beneath the coffee
tree to catch the cherries as a picker grabs each branch at
the base and pulls everything off towards the tip. This requires
a further step of sifting the cherries from the other debris
stripped off the branches.
Mechanical harvesting exists in limited regions. It is similar
to the method used in orchards to shake nuts and fruit from
the branches of almond and orange trees. Because this requires
fairly flat terrain and long, even rows of trees to be effective,
its practice is limited primarily to regions in Brazil at
this time.
