Tesco wine boss Dan Jago will join Berry Bros & Rudd as chief executive in October.
Jago will leave his post as group wine director at the supermarket, which he first joined in 2006 as category director for wine, beer and spirits.
Before joining Tesco he was joint managing director of Bibendum and he is a board member of the Wine & Spirit Association.
He will have responsibility for the overall Berry Bros business including its wine and spirits divisions and international operations.
He will work with another new appointment, chief operating officer Jeremy Parsons.
Berry Bros chairman Simon Berry said: "I believe he brings one of the best business brains in the industry and we are very lucky that he's joining us.
"We will benefit hugely from his deep knowledge of the wine, beer and spirits markets as we further develop the expanded scope of our business in the UK and overseas.
"Dan has huge respect for our history and traditions. He is perfectly placed to help build an even brighter future for the company."
Jago said he was "proud and excited" to be joining the Queen's wine merchant.
He added: "It's a great business, an extraordinary heritage and a treasured brand.
"I have spent most of my working life in the drinks business and, for me, this is perhaps the ultimate job.
"Berrys' ethos, emphasis on quality, its relationships with producers and its mission to take the best care of its customers are a perfect fit for me."
Jago's name was linked with the chief executive's role at Majestic Wine after the departure of Steve Lewis earlier this year, a job that eventually went to Rowan Gormley.
Dan Jago's father, Tom Jago, was the inventor of Baileys.
