During the three-day event, a bespoke Land Rover Defender, which has been fitted with a Pol Roger champagne bar, will be on site to provide guests with a glass of champagne.
Elizabeth Inman, event director of the Land Rover Burghley Horse Trials, said: "We are delighted to welcome Pol Roger on board as our official champagne.
"This renowned brand shares many of the same values that we espouse at the horse trials including quality, tradition and hospitality."
James Simpson MW, managing director, Pol Roger Portfolio added: "It is a great honour to be named the official champagne of the Land Rover Burghley Horse Trials and further to consolidate our long standing relationship with Land Rover, and indeed the three-day eventing world.
"We look forward to seeing the top equestrian athletes competing for the prestigious title, as well as the Pol Roger Portfolio Defender and pop-up bar set up in the beautiful surrounds of the Burghley Parkland, a perfect setting to enjoy a glass or two of champagne!"
The televised horse trials, which have previously attracted over 160,000 visitors, will be taking place in Stamford, Lincolnshire, on 3-6 September.
