Champagne Thomas de Marne is a small family-run organic Domaine, heir to the renowned Champagne Val'frison. Thomas, son of Thierry de Marne and Valerie Frison, is carrying on the work started by his parents, who took over the vineyards in 1997. Initially, the grapes were sold to the local cooperative, but since 2003 the vineyards have been converted to biological viticulture. In 2007, with the first certified organic harvest, they began producing small quantities of champagne under the De Marne Frison brand.
