The history of the Lhéraud estate began in 1680 when Alexandre Lhéraud decided to plant grapevines in his garden in Petite Champagne, in a limestone terroir with distinct seasons that gives Lhéraud cognac length and minerality. Today it spans 85 hectares and is planted with Uni Blanc, Colombard and Folle Blanche. The cognacs are aged in Limousin oak in Charente blonde stone cellars, without any additions or reduction. This Garden of Eden is home to the house's oldest cognacs, which have been transferred into demijohns.

Guy Lheraud Cuvéee 20 is a blend of eaux-de-vie aged for 20 years in Limousin and Tronçais oak barrels. The grapes were grown in Petite Champagne, one of the most prestigious crus in the appellation.
