Stephen Moss CBE is to replace Peter Espenhahn as chairman of Bibendum.
Moss joins Bibendum after a career working across the wine distribution and restaurant sectors, and was a partner at Michael Druitt Wines.
He has been brought in by Bibendum for his experience in growing SMEs and helping to lead businesses through periods of development and change.
Espenhahn, who has been chairman for the past 14 years, said: "I have been privileged to be part of such a dedicated team. I am also delighted that I will be succeeded by Stephen who, I am confident, will be able to help the team take the company on to the next stage of its development."
Moss said: "I am delighted to be back in the wine and spirit distribution business again and it is a privilege to have been appointed chairman of such a dynamic and successful company as Bibendum. "
Michael Saunders, Bibendum's managing director, said: "While we are obviously disappointed to be losing Peter's wealth of experience and expertise, I am delighted that someone of Stephen's calibre is joining the board as chairman and look forward to working with him to further Bibendum's success in the future."
