|   Champagne Jacquesson  
             
               
              Founded in 1798 by Memmie Jacquesson and today stakes a claim as the oldest   independent Champagne house. In 1974 it was purchased by the Chiquet family, and Jacquesson is   now run by brothers Jean-Hervé and Laurent Chiquet, who oversee the vineyards   and day-to-day running of the winery.
