Upmarket caterer Rhubarb has secured a five-year contract with Goodwood Estate in West Sussex, in a deal worth around £60m in total turnover.
The contract, which will start on 16 March 2016, will see Rhubarb take over from incumbent caterer Compass Group, which has held the contract for more than 25 years.
Rhubarb will oversee the catering at the estate's key festival events including Members' Meeting, Festival of Speed, Revival and the 19 days of racing that include Qatar Goodwood Festival.
Goodwood owner Lord March said: "We chose Rhubarb as I felt the passion for what they do, their attention to detail and their people really set them apart from the competition. I am excited by the fresh ideas they can bring to our key events and the support they will provide in moving the overall experience forward."
PB Jacobse, managing director at Rhubarb, added: "We are incredibly proud to have been chosen by Goodwood and to be a part of the world's leading sporting estate."
Rhubarb currently has contracts at several London visitor attractions including Sky Garden at 20 Fenchurch Street, Royal Albert Hall, Saatchi Gallery, Heathrow T3 and T5, London City Airport and Royal Ascot Racecourse.
Goodwood has been home to the Dukes of Richmond and their family for more than 300 years. The estate is recognised for its range of sporting activities including horseracing, motor racing, golf, flying, shooting and cricket.
