Roger said: "I am very excited to have this opportunity to express my passion for champagne through this limited edition cuvee. I hope you enjoy it as much as I do."
A festival spokeswoman said: "This will be the first time the champagne has been tasted by anyone other than the winemaker and Roger Daltrey."
Along with the champagne, a signed ice bucket has been produced in a limited run of 499 to sell at £650 each.

One festival-goer, Jason Hargraves, 51, from Norwich, surprised his wife Juliet for her 50th birthday with "glamping" tickets to see Queen.
Jason, a father of two girls, said: "It's both of our first time at any big festival - it was an ambition to be here."
Juliet said: "I had no idea I was coming here so it was a great surprise. A lovely surprise."
DJ Lemon, from Southsea, Hampshire, who will perform as Its a Sin in the Hipshaker tent on Sunday, said: "The atmosphere was insane in there last night, Rhythm Of The 90s was huge, just crazy vibes."
