Coffee as a beverage didn't emerge until the 15th century in the Near East and Eastern Africa. It was introduced to the European continent sometime in the late 16th century, and coffeehouses boomed in England and Italy in the 1650s, and among other European nations in subsequent decades. The coffee drink of your typical 17th century English coffeehouse was similar to that of modern unfiltered Turkish coffee: Roasted grounds were simmered in water with milk and a lot of sugar added. If you're looking for more information on the fascinating history of coffee and its surprising social impacts, I'd recommend Tom Standage's book A History of the World in 6 Glasses.
