Harvest
It takes 8-9 months for the coffee berries to ripen. Generally, the longer the ripening time, the better the coffee. Although mechanical pickers do exist, most coffee is still harvested by hand.
There are two main methods of extracting the bean from the berry: the wet method and the dry method, which give the coffee a different character.
The wet method is used mainly in locations with good reserves of water, e.g. Central America and Colombia. Once the berries have been trimmed of leaves and stalks, they are immediately threshed to remove the skin and pulp. Then they are left to ferment for 12 to 36 hours. This fermentation gives the “washed” coffee an acidic character.
The next step is to wash and rinse the beans in running water before they are dried. The beans have the parchment skin intact and are called pergaminos. This membrane is threshed off before the cleaning and sorting.
The dry method is used where access to water is limited, e.g. in Brazil. Immediately after harvesting, the berries are trimmed of leaves and stalks. The berries are then rinsed in narrow channels of running water. At this point unripe berries are also separated from the ripe ones.
The coffee berries are then laid out on cement or stone terraces to dry in the sun. They are turned several times a day for even drying. At night the berries are shovelled up into heaps and covered.
After 1-3 weeks, the berries are dry and the pulp has become dark and wrinkled. The dry pulp and the parchment skin are threshed off before the cleaning and sorting.
