Built by the noble LorÃ© de la Ragotiere family in the fourteenth century, ChÃ¢teau de la RagotiÃ¨re was purchased in 1979 by the Couillaud brothers. After acquiring the property, Bernard, FranÃ§ois, and Michel discovered an old cellar in the chapel housing vintages dating back to 1947. The Couillaud brothers strive to carry on the tradition of making high quality, long-lasting Muscadets. In addition to their Muscadet, the Couillaud brothers produce estate bottled Chardonnay under the Domaine de Bernier and Les FrÃ¨res Couillaud labels. The wines are from 15-year-old vines and 8% of the Bernier Chardonnay is barrel-fermented in French oak. The remainder, like their Muscadet, is aged â€œsur lieâ€ in tanks, creating Chardonnays with lively acidity.
