The use of oak became controversial in the Chablis when some winemakers in the late 20th century went back to wooden barrels in winemaking, using oak barrels. So-called "traditionalist" winemakers dismissed the usage of oak as counter to the "Chablis style" or "terroir", while "modernist" winemakers embrace its use though not to the extent of a "New World" Chardonnay. The amount of char in oak barrels used in Chablis is often low, which limits the "toastiness" that is perceived in the wine.
