In 1978, just after purchasing Château de la Ragotière, the Couillaud brothers also purchased an estate on a beautiful hillside in the Loire Valley with a schist terroir. Part of the plot still needed to be planted, and Bernard Couillaud was curious about which varietals would do well in this area, where the two dominant varietals were Melon de Bourgogne and La Folle Blanche. After some research, the Chardonnay grape piqued his interest due to its unexplored potential in a maritime region. He launched the project and immediately set out for Chablis to research and learn more about Chardonnay. Planting started in the spring of 1987 and, over the course of three years, 42-acres were planted on the hillside plot.
Soon after the project began, Danny Haas of Vineyard Brands became interested and wished to taste the final product. In 1990, after having tasted Bernier Chardonnay amongst several other wines from the brothers, he was convinced of its potential and Bernier was introduced to the market.
