Mapping Nebbiolo

Nebbiolo, the variety used in the Langhe's famed Barolo and Barbaresco wines, is considered Italy's most noble grape. Its name is thought to have been derived from the Italian word for fog (nebbia), a condition which is common in Barolo during the September-October maturation period of the variety. I have previously written on The Langhe as a wine region but, after reviewing TONG No. 16's focus on the region's key variety, I have attempted to map Nebbiolo to its regions, its requirements, its wines, and its styles.

A fuller description of the areas where Nebbiolo is planted in Italy has been described in a series of posts on this blog. During the course of a journey through the geographical locations and naming conventions associated with the Nebbiolo grape, we have encounterd it as Chiavennasca (Valtellina, Lombardia), Picotendro (Donnaz, Valle d'Aosta), Spanna (Vercelli-Novara region of Alto Piemonte), Prunent (Val d'Ossola) and Nebbiolo (Langhe-Roero). 

Detailed maps of Barolo DOCG are shown below.

The below chart was compiled from a BBR blog post (bbrblog.com) by David Berry Green in which he tasted Le Rocche offerings from a number of producers in order to determine whether the subject vineyard was Grand Cru material. His conclusion? "It should be ranked alongside other prized Barolo vineyards such as Brunate, Cerequio, Vigna Rionda, Monprivato, Falletto, Cannubi, Monvigliero, and Bussia."
