Heidsieck Monopole will kick off a three-year partnership with Barclaycard presents British Summer Time Hyde Park this June, acting as the festival's official Champagne partner.
At the 10-day event, which will see The Who and Taylor Swift take to the stage, Heidsieck Monopole will be the exclusive Champagne and feature in all bars and VIP areas. The 'invite-only' Heidsieck Monopole Treehouse, a Champagne bar in the sky, will also be built.
Nick Hyde, chairman of owner Vranken Pommery UK, said: "Being part of this fantastic festival is a big step in our commitment to grow wider awareness for Heidsieck Monopole, one of the best selling Champagnes in the UK."
A social media campaign and consumer engagement, both on and off trade, is planned to promote the partnership.
AEG Global Partnerships brokered the deal.
