Dom Pérignon (; ) is a brand of vintage Champagne. It is named after Dom Pérignon, a Benedictine monk who was an important quality pioneer for Champagne wine but who, contrary to popular myths, did not discover the Champagne method for making sparkling wines. History Dom Pérignon (1638–1715) was a monk and cellar master at the Benedictine abbey in Hautvillers. He pioneered a number of winemaking techniques around 1670—being the first to blend grapes in such a way as to improve the quality of wines, balance one element with another in order to make a better whole, and deal with a number of their imperfections; perfecting the art of producing clear white wines from black grapes by clever manipulation of the presses; enhancing the tendency of Champagne wines to retain their natural sugar in order to naturally induce secondary fermentation in the spring; being a master at deciding when to bottle these wines in order to capture the bubble. He also introduced corks (instead of wood), which were fastened to bottles with hemp string soaked in oil in order to keep the wines fresh and sparkling, and used thicker glass in order to strengthen the bottles (which were prone to explode at that time). The development of sparkling wines as the main style of production in Champagne occurred progressively in the 19th century, more than a century after Dom Pérignon's death. The first vintage of Dom Pérignon was 1921 and was only released for sale in 1936, sailing to New York in the liner Normandie. The brand, not exploited, was given by Champagne Mercier to Moët in 1927 for a wedding between the two families. In 1935, 300 bottles of a 1926-vintage precursor to Dom Pérignon were sold to Simon Bros. & Co., the company that imported Moët in the United Kingdom, who gave two bottles to each of their 150 best customers to commemorate their centenary. While these bottles were almost identical to the subsequent Dom Pérignon releases, they did not display the Dom Pérignon name, rather "Champagne specially shipped for Simon Brothers & Co's Centenary 1835—1935." The wine got immediate attention in the marketplace and 100 boxes of the 1921 vintage were shipped to the United States shortly thereafter, this time displaying the Dom Pérignon name. James Buchanan Duke, the billionaire who had founded the American Tobacco Company, ordered 100 bottles for himself. The 17 bottles sold at
