Heidsieck & Co. Monopole is one of the oldest Champagne firms in all of France's Champagne region. The origins go back to the 18th century. In 1818, Heidsieck was appointed suppliers of Champagne to the king of Prussia, emperor of Germany; in 1911, it was appointed suppliers of Champagne to the English court. In 1933, Heidsieck Champagne was featured at the Swedish court and at the table of Csar Nicolas II (the latter ordered over 400,000 bottles a year for his personal use).
