An interesting article by AlfonsoCevola in his blog:
Cevola:Piemonte
regarding the proposal in the Piemonte to allow a Piemonte DOC Nebbiolo DOC Nebbiolo put forth by the Asti/Monferrato producers.
This proposal is being fought tooth&nail by the Barolo/Barbaresco producers, fearing that it would dilute their supremacy in the Piemonte and cause their prices to "crash". In the WE, Kerin O'Keefe came down squarely on their side and opposed this DOC. Alfonso takes a more balanced view on the subject, acknowledges the B/B producer's fears, but suggests it might lead to wider plantings of Nebbiolo across the Piemonte and, perhaps, the discovery of the next Gattinara.
Anyway, quite a good read on the controversy.
