Chapel Down also makes the Curious Brew beer range and produces cider, but the bulk of its business lies in wine and Harvey will head this up.
Harvey, formerly business development director at LVMH, will join on 14 September
Thompson said: “We are delighted to welcome Mark to the team. He joins at an exciting time. There are huge opportunities and challenges ahead in both English wine and beer and we need the very best talent at Chapel Down to ensure that we are able to better build our business and our brands.
“Mark brings a wealth of experience in luxury drinks development as well as the personality and intelligence to help us shape the future of the English wine industry. His appointment will enable us to make our wine and beer business as good as they can be.”
Harvey added: “I'm thrilled to be joining the Chapel Down team at such an exciting time for the English wine industry. We have a winning combination of outstanding wines, a fantastic team and world-class customers. I'm really looking forward to the challenges and enormous opportunities ahead.”
