In 2011, Tim Matz took on the job as the MD of Accolade Wines' North American division. Since then, the company has bought a clutch of wine brands - many of which are now part of Matz's purview - and has lost its chief executive. Late last month, just-drinks' deputy editor, James Wilmore, sat down with Matz at ProWein to talk through the challenges the company faces, the US wine market and the positive aspects of working for a private equity group.
