J-M Brocard has been a Chablis producer since the early 1970s, and has grown to 60 hectares of vineyard, of which 40 are biodynamic and the remainder organic.. Ste, Claire is a vineyard of sufficient quality to have its own name, but not enough to merit premier cru classification. Nonetheless, wines from the Ste. Claire vineyard are superior to most village level Chablis with lovely notes of sea spray and iodine with lemon zest overtones.
