The
soils of the Barbaresco zone are composed primarily of
calcareous marl dating from the
Tortonian epoch. The area is typically divided into three regions based on the principal towns - Barbaresco, Neive, and Treiso.
Barbaresco The vineyards around the town of Barbaresco make up for 45 per cent of Barbaresco production, with many of the area's largest wineries located in town. Wines from this area tend to be relatively light in colour and body, but very well structured and aromatic. Neive is responsible for 31 per cent of Barbaresco's production and makes some of the most full-bodied and tannic examples of the wine. The area is bisected by a valley, in the midst of which lies the village of Neive itself. The vineyards have been described by Masnaghetti as lying in three distinct subregions: The northern area contains gentle ridges. The southwestern region consists of a low hill, with the Cascina San Cristoforo lying right on top. A gentle slope runs down toward the Barbaresco village to the west. Steeper slopes lie to the south and east, the latter marked by a deep basin at the edge of the hill. The southeastern region is a series of ridges.
Moscato is a significant grape here, mostly planted in the cooler areas facing eastwards, while
Nebbiolo is more common on the warmer ridges with a westerly orientation.
Treiso Located south of Barbaresco, with vineyards on the highest hilltop sites in the area, Treiso wines tend to be the lightest in body and are principally known for their finesse. A smaller area, Treiso accounts for 20 per cent of the Barbaresco zone's production.
Vineyard classifications Beginning in the late 19th century, there have been attempts to classify the area's vineyards into
Burgundian-like
crus based on which areas produced the best wines. The Italian wine critic
Luigi Veronelli created one such list in the 1960s, and other writers and
viticulturists attempted to create their own in the 1970s. Today, many follow the lists compiled by the
négociant, which rank grapes by price based on performance. These lists typically include the
Asili, Martinenga,
Montefico, Montestefano and
Rabajà vineyards in Barbaresco, the
Albesani, Santo Stefano, Bricco di Neive and
Gallina vineyards in Neive, and the
Pajorè vineyard in Treiso. In 2007, the Barbaresco Consorzio was the first to introduce the
Menzioni Geografiche Aggiuntive (additional geographic mentions), also known as
MEGA or
subzones; there were 65 officially approved subzones, with one more approved in 2010, bringing the final number to 66. The main goal was to establish official boundaries for some of the most storied crus to protect them from unjustified expansion and exploitation. Following the introductions of subzones, the term Vigna (Italian for vineyard) can be used on labels after its respective MEGA and only if the vineyard lies within one of the approved MEGAs. ==Wines==
