I have seen a question: Which Beaujolais cru is allowed to use Pinot Noir? I cannot find the answer anywhere. Any idea ??
I like to look at the AOC documents themselves in these cases. You can find them linked in the compendium on this site; for example, here is the one for St Amour https://www.guildsomm.com/webupload/AOCs/CDC_Saint-Amour.pdf?Redirected=true
The answer appears to be that none of the 10 Beaujolais Cru AOCs allow Pinot Noir in the encepagement.
Nor in the assemblage.
