Well, I too fail to see much cause for alarm. I certainly don’t think that a few Piemonte Nebbiolos, even if so-so, would suddenly threaten the position of Barolo or Barbaresco, let alone bring the Nebbiolo varietal in disrepute. At most, it would increase competition in the bottom segment of the Nebbiolo market and that wouldn’t be such a bad thing from a consumer point of view, I think.
Nor do I see how this proposal threatens the subzone reform that has just been carried out in B&B. Such zoning was perhaps needed in order to settle what the cru labels already used actually meant and who had a right to call a wine this or that. But the reform would hardly be in vain even if some Piemonte Nebbiolos were added.
Certainly, it stands to reason that on average, the prospects of growing good Nebbiolo are better in those areas where the grape already has a DOC or DOCG of its own. But there is much to suggest that those areas are already overexploited with regard to Nebbiolo and that the vine is now to a significant extent planted in vineyards that are less than perfectly suited to it. It might well be that there are pockets here and there in other regions where the vine would work pretty well, and better than in some places where it is already grown.
One thing that I think O’Keefe should have mentioned, if she knew, or checked up, if she didn’t, is that Nebbiolo is already allowed to be issued as Piemonte Rosso DOC or as Monferrato Rosso DOC (if coming from the vast Monferrato district which covers pretty much all of Piedmont where there is much hope of growing decent Nebbiolo and where it doesn’t yet have its own DOC or DOCG). Some such Nebbiolo wines are already on the market. A few examples are provided via the links below.
So contrary to what one might think when reading O’Keefe’s article, it isn’t really that Nebbiolo is forbidden or refused a DOC label outside Langhe, Roero and the scattered DOCs and DOCGs in the north. The only thing producers can’t currently do under the Piemonte or Monferrato DOC is flaunt Nebbiolo as part of the DOC designation, although they are of course free to indicate the varietal in other ways. So perhaps it is only the possibility to spell out the name of the grape as part of the DOC label that the Asti/Monferrato consortium is after (if it is actually responsible for the proposal).
Here are some examples of Piemonte Rosso or Monferrato Rosso Nebbiolos:
