Claude Moët (1683–1760) was a French vintner and wine merchant who founded the Champagne house that later became Moët et Chandon. Moët was the first winemaker in Champagne to exclusively produce sparkling wine. An expert salesman, Moët advocated the importance of personal contact with customers. During the 1730s, he networked extensively within the royal circles of Versailles and soon became one of few merchants accredited to serve the royal court.
