Which AOC is most likely to produce Chardonnay that has spent time in barrel?

Meursault is renowned for its rich, full-bodied Chardonnay wines that frequently undergo barrel aging. The region is located in the Côte de Beaune part of Burgundy and benefits from the warm climate, which allows the grapes to develop ripe flavors and a creamy texture. Barrel aging in French oak is a common practice here, imparting complex flavors such as vanilla, toast, and spice to the Chardonnay, in addition to enhancing the wine's body and mouthfeel.

While Chablis, Pouilly-Fuissé, and Montagny also produce Chardonnay, their typical winemaking styles and regional characteristics do not emphasize oak aging to the same extent as Meursault. Chablis, for example, is known for its crisp, mineral-driven wines, often made in stainless steel to preserve freshness. Pouilly-Fuissé and Montagny may have some wines aged in oak, but it is less common than in Meursault. Thus, Meursault stands out as the AOC most likely to produce Chardonnay that has spent significant time in barrel.
