_Customary preparation of the berry in the pulp_.--When the coffee is
picked and brought into the village, it is piled up in a heap in the
open air, and left in that manner for twenty-four hours. Thus heaped
up it gets warm, and this creates a certain fermentation of the juice
which is in the berry. That fermentation promotes the drying and
loosens the silvery pellicle which is attached to the bean inside the
parchment, and which cannot be entirely got rid of in any other way.
Coffee which still retains that pellicle is called in trade "grey
coffee," and is lower priced than good clean sorts. After the
fermentation, the coffee is spread out in rather thick layers, and
turned over twice a day. If it rains during this first spreading out,
the coffee does not require to be sheltered, as the washing causes the
juicy substance to evaporate, and this accelerates the drying
afterwards.
In proportion as the coffee becomes dryer, the thickness of the layer
must be reduced, and the turning over must be more frequent till the
coffee is quite dry outside and the pulp has become hard.
Then the coffee is laid out on drying floors, which can be easily and
speedily covered in rainy or damp weather, and is dried by the
powerful heat of the sun.
This system of drying in the pulp requires six weeks or two months, as
it is advisable not to be over hasty with drying.
When the coffee is entirely dry, it is either at once pounded or
placed in the stores to await that operation. In order to know if the
coffee be sufficiently dry, take a handful of it and shut your hand
close; shake it to your ear, and listen if the beans rattle freely in
the pulp. Or try them by biting the berry, and see if the bean and
pulp are both brittle and crisp, which shows that the fruit is dry
enough.
