Coffee usually refers to the roasted and ground beans of the Coffea plant. It was first discovered in Ethiopia by the indigenous population. It was first cultivated circa 675 CE in Arabia. By the ninth century, it was also drunk in Persia. Abu ibn Sina (aka Avicenna) was acquainted with coffee around 1000 CE.
During the 17th century coffee houses opened in England and became quickly popular meeting places for men to engage in discussions. This distressed alewives (due to competition) and some women (who believed coffee reduced men's virilty).
