The family owned house of Duval Leroy was founded in 1859 and makes both organic, biodynamic and conventional champagnes. All provide good price/quality ratios and are worth trying. The house is set in Vertus in the Cote de Blancs and is thus specialized in chardonnay. Look for the Brut marked "Organic".

Top organic/biodynamic and natural champagnes
Chilly, humid Champagne should be a challenge for organic growers. Before Anselme Selosse of Champagne Jacques Selosse or Champagne Fleury proved them wrong, it was even said that it couldn’t be done. The climate was too risky, and a grower could lose an entire crop to mildew. However, the region is now an excellent example of organic/biodynamic and ”natural” winemakers producing more interesting wines than the standard. Here is a list of champagnes with personality, class and good price/performance (though not all by any means cheap!). They are not the only ones, however, and I encourage you to ask your retailer for other suggestions in the category!
