In 1584, Pierre Gosset, alderman of Aÿ and winegrower, mainly made red, still wines with the harvest from his own vineyards. This makes Gosset the oldest winery in Champagne. At that time, champagne as we know it did not yet exist. Gosset sold a still, mostly red wine made from the grapes from its own vineyards. Champagne and wine from Beaune in Burgundy competed for the favor of the French kings at the time. When, thanks to the invention of Dom Pérignon, sparkling champagne could be made and sold in bottles, the house of Gosset also became involved in the production of white sparkling champagne. And in the 18th century the production of still wines made in and around Aÿ changed to bubbles. Malolactic fermentation is carefully avoided in order to preserve the malic acid, which provides the natural fruity aromas. Gosset assembles the best Crus of the Marne district (Grand Crus and Premier Crus), with an average classification of 95% on the official Cru scale ("échelle des crus").
