The apocryphal tale goes like this: In the late 1600s, the Turkish army swept across much of Eastern and Central Europe, arriving at Vienna in 1683. Besieged and desperate, the Viennese needed an emissary who could cross Turkish lines to get a message to nearby Polish troops. Franz George Kolshitsky, who spoke Turkish and Arabic, took on the assignment disguised in Turkish uniform. After many perilous close calls, Kolshitsky completed his valiant deed, delivering news of the Poles’ imminent rescue to Vienna.

On September 13, the Turks were repelled from the city, leaving everything they brought, including strange bags of beans, which were thought to be camel feed. Kolshitsky, having lived in the Arab world for several years, knew these to be bags of coffee. Using money bestowed on him by the mayor of Vienna, Kolshitsky bought the coffee and opened Central Europe’s first-ever coffee house (The Blue Bottle), bringing coffee to a grateful Vienna.
