Picking: the natural way of harvesting Manual procedure by which only ripe fruit are
picked. This method is characterised by:
slowness
high quality of the product obtained
evenness of the harvest
high costs
Stripping: the quick harvest
Procedure that can be performed by hand or
machine, stripping the plant of fruit and leaves.
Its main characteristics are:
speed
damage to plants
unevenness of the harvest
low costs
SEPARATING THE BEAN FROM THE PULP AND LEAVES
Coffee can be processed in various ways.
THE "WASHED" BEANS METHOD
This method is a water-based treatment after
picking.
The beans are processed through the following
stages:
cleaning
depulping (mechanical separation of the pulp and bean by rollers)
fermentation (with water to remove mucilage - 12/24 hours )
washing (120 l/kg)
sun drying for 9 - 10 days or in dryer
hulling and glazing
grading (large / medium / small / caracolito)
The method is:
time-consuming
costly
technically complex
but ensures a high-quality coffee - even, aromatic and clean-tasting.
The process determines the final colour of the
bean:
Coffea Arabica becomes greenish-blue
Coffea Robusta becomes yellowish-green
THE "NATURAL" DRY (UNWASHED) BEANS METHOD
This method is a dry treatment after stripping.
The beans are processed through the following
stages:
cleaning and washing (separation from leaves, wood chips, gravel or soil)
drying (sun dried or in dryers -1-3 days at
45-60° C)
hulling (separation skin/parchment from the bean)
grading (large / medium / small/ caracolito)
This method is:
rapid
economical
technically simple
more ecological
though the sugar content is higher.
The process determines the final colour of the
bean:
