Was looking for something else in my '63 lichine and saw:
great Growths (Grand Crus)
Wine must be made exclusively from Pinot Noir, Pinot Liebault, and Pinot Beurot grapes. A maximum of 15% Pinot Blanc or Chardonnay grapes may be used at the discretion of the winemaker.
am looking for other similar references.
I think the Liebault and Beurot are very close cousin to Noir, and the Pinot Blanc mentioned is a white clone of Pinot Noir, and not the same as Pinot Blanc from other regions.
