The Arabs are known to have drunk coffee as of 850 A.D. It took Europe almost seven centuries to make its acquaintance. Although Mocha, a town in southwestern Arabia, had become an active port for coffee export by 1450, coffee did not appear in Europe until 1517. By 1580, Turkish coffee was imported in bulk to Italy, through Venice; by 1643, coffee was popular in Paris; in 1632, the first coffee shop opened in London, followed by the first coffee house in Oxford in 1650. Vienna, which was to become so famous for its coffee houses, did not catch up until 1683.
