Acquired in 1974 by Jean Chiquet, the House holds vineyards across the Grands Crus of Aÿ, Avize and Oiry and the Premier Crus of Hautvillers, Dizy and Mareuil-sur-Aÿ. It is headquartered in the village of Dizy, located in the Vallée de la Marne growing region. Currently at the helm of this revered House since the 1980’s are sons of Jean and brothers, Laurent and Jean-Hervé Chiquet. Under their visionary leadership, Jacquesson has become famous for two unique approaches to champagne. The first; they have gone against the Champagne ‘norm’ by making the radical decision to reduce their yields in the vineyard in order to produce grapes of higher quality, effectively reducing their production of champagne. Nearly 90% of their grapes are from their own herbicide free vineyards and they only acquire additional grapes from growers who have the same exacting standards as they do. Secondly, Jacquesson decided to forgo its non-vintage blend and instead made the innovative decision to produce a cuvée based on a single year or vintage, giving it a number that changes annually - in this case 742. From 2019 onwards, all Jacquesson champagnes are a one hundred percent reflection of the brothers' vineyard practices and are produced using their revolutionary methods. They are also well known for their highly sought after, small production lieu-dit cuvées.
