As we have already described in the paragraph on the coffee plant, seeds are obtained through the drying or the washing process; during the latter, coffee beans are harvested, dried, comminuted and finally cleaned. Grains’ extraction is made by a dry or wet working-process which, in the first case, consists in picking, drying, shattering and cleaning, the grains so obtained are packaged in sacks and exported.
The importing countries work coffee with a blending of grains first and then with a roasting of them, after that grains are cooled and then grinded.
To be used for the real drink’s preparation, grains have to be worked in a process we can synthetize in three phases: blending, roasting and grinding.
Implements used for this are several and they have been improving in time, from the oldest ones to the actual ones which have recourse to the latest technologies..
