The vineyards are classified as Premier Cru (Chamery, Vrigny, Coulommes la Montagne) and Grand Cru (Verzenay, Verzy). Anxious to develop the style of his Champagnes towards greater complexity and maturity, André Bonnet has also started the conversion of the Domaine to organic farming and the development of alternative methods based on phytotherapy. In the cellar, oak casks, steel or cement tanks are used; each wine ferments in the container which will allow it to express its qualities in the best possible way, preserving its ageing potential.
