Klatchian coffee
Klatchian coffee is a fictional substance from the Discworld series. It is a strong, nearly magical coffee, brewed in Klatch and drunk only by the initiated in very small cups. Not only does it sober you up, is sends you to the other side of sobriety. This state is refered to as knurd, which dispells the soft pink cushions of sobriety and lets you see the world for what it is. In Klatch it is drunk with Orakh (a very violent alcohol made from scorpion venom and cactus sap) to counteract its effects. After a few screams, a lie down and a stiff drink, the occasional drinker will try never to be knurd again....
Klatchian coffee is (presumably) intended as an exaggerated version of Turkish coffee.
