The Bonneau du Martray family is recognized as one of the best producers in the Corton appellation, and their Corton-Charlemagne is renowned as one of the benchmarks of the region. Produced from low-yielding vines, 16 different parcels of grapes are vinified separately in order for their respective "terroirs" to be reflected in the final wine. Fermentation begins in stainless steel and after 5 or 6 days is completed in cask. The separate cuvées are matured in one-third new oak barrels for 12 months before being assembled and returned to cask for another 6 months prior to being bottled.
