Turkish coffee is coffee prepared by boiling finely powdered roast coffee beans in a pot (cezve), with sugar or withour sugar, and serving it into a cup, where the dregs settle. Istanbul was introduced to coffee in 16. century during the reign of Sultan Suleiman the Magnificent by Özdemir Pasha, the Ottoman Governor of Yemen, who had groawn to love the drink while stationed in that country. Coffee soon became a vital part of palace cuisine and was very popular in court. The position of Chief Coffee Maker (kahveciba??) was added to the roster of court functionaries. The Chief Coffee Maker's duty was to brew the Sultan's or his patron's coffee, and was chosen for his loyalty and ability to keep secrets. The annals of Ottoman History record a number of Chief Coffee Makers who rose through the ranks to become Grand Viziers to the Sultan.
