In 2004 Oliver, a studied philosopher and literary scholar, bid adieu to the world of theatre to open a bar in Berlin Prenzlauer Berg. Today “Beckett’s Kopf” is considered one of the country’s best bars and, in 2013, Oliver was named the Mixologist of the Year. He supports the Freimeisterkollektiv with his specialized knowledge and creative impetus. Oliver supported Thomas Neubert in the development of his GIN 206. Thanks to his initiative, Josef Farthofer and Ralf Rüller have come forward with a coffee spirit from two different coffee varieties.
