Piper-Heidsieck, which has supported the movies since 1933 when a bottle of Piper-Heidsieck appeared in Sons of the Desert, the film debut of Laurel and Hardy, is the champagne partner of the 93rd Oscars taking place this Sunday, April 25. This marks the seventh year of a long-term partnership between Piper-Heidsieck and the Academy of Motion Picture Arts and Sciences.
