Domaine Bonneau du Martray is in Pernand-Vergelesses, and It is the only estate in Burgundy that makes nothing but Grand Crus. It is now primarily owned by American businessman and sports industry magnate Stanley Kroenke, who also owns Screaming Eagle in Napa Valley. Though the estate has been making wine for centuries, it is only since the 1970s that it bottled its own wines. About 90 percent of the estate’s 27 acres is in Corton-Charlemagne, and Corton-Charlemagne is the domaine's most famous wine. Robert M. Parker Jr. has called Bonneau’s Corton-Charlemagne “exquisite” and “age-worthy.” About 4,000 cases of Corton-Charlemagne are produced annually. Also produced are Aloxe-Corton, Le Corton and Pernand-Vergelesses. The estate is one of the most prestigious in the region and was a pioneer in biodynamic viticulture in Burgundy.
