For many people, drinking coffee is an elegant affair, but there is a type of coffee that started out "dirty" and became famous for being "dirty," to the point that even germaphobes would find it unbearable to watch. There are mainly two schools of Dirty coffee on the market: one involves extracting espresso directly onto the surface of cold milk, creating the visual effect of "tainting" the milk; the other pursues "filth" in the truest sense, deliberately letting the liquid overflow the cup and saucer, sprinkling on cocoa powder and the like, to create a state of "messy filth." In London, England, a brand called "Italian Bear Chocolate" has launched a "Triple Chocolate" series of drinks. Whenever someone orders a coffee and adds the "chocolate triple," the barista first picks up a ceramic cup with a saucer, moves it over three large tubs of chocolate in different colors, then uses a large ladle to scoop them up one by one and pour them over the rim of the cup—white chocolate, milk chocolate, dark chocolate—striving to let the cup fully "bathe" under each kind of chocolate sauce. Finally, after the barista takes this cup, dirtied to the extreme, to receive hot water and espresso liquid, this specialty coffee is complete. [more…]
