In the raw coffee warehouse of the Schreyögg coffee roasting company many different species of raw coffee are stored, including washed and unwashed Arabica and Robusta species from all over the world, which are grown in a wide belt between the 23rd parallel north and the 25th parallel south round the equator. In dry processing of the unwashed coffee the cherries are dried on stone or concrete floors. Then the beans are disengaged from the pulp by machines. In wet processing of the washed coffee the pulp is removed by a so-called pulper. The skins and the pulp are washed away with water.
The areas where Robusta beans, roundish beans, are grown are at an altitude of approx. 800 m, whilst Arabica beans, which tend to be more oval and flat, are cultivated at approx. 800-2200 m.
