REPROCESSING

The profession of the coffee pickers was closely linked to the commercial classification of coffee. As the amount of defective beans and impurities could reduce the value of coffee, in some cases it was useful to make a selection of these grains to improve their quality, and therefore its classification, this task was included in the reprocess. It is with this objective that were formed the warehouses of coffee picking- whether independent institutions or belonging to some exporter - in the early twentieth century.

The task was performed predominantly by women, who picked it manually, picking defects one by one and separating them from the rest of the coffee - which gave them the nickname "pianists". Generally they were temporary workers, having no connection with the warehouses and they earned per each sack picked, which was common due to fluctuations in productivity.

Manual picking began to fade in the 70s, when electronic pickers with superior productivity to manual labor, and lower cost, start appearing on the market, separating impurities through ventilation sieve, and then photosensitive machines that distinguished green beans and other defective grains considered defects.
