Rivette MGA, La Morra, Barolo
Introduction
Rivette is one of the officially designated Menzioni Geografiche Aggiuntive (MGA) in the commune of La Morra, part of the Barolo DOCG in Piedmont's Langhe hills. The MGA system, introduced in 2010 within the rules of the Barolo DOCG, formalized what had long been an informal recognition of individual vineyard sites throughout the denomination. While Rivette does not occupy the same commanding position in historical literature as La Morra's most celebrated sites (Rocche dell'Annunziata, Brunate, and Cerequio) it nonetheless represents a legitimate expression of this commune's distinctive terroir.
La Morra is the largest of Barolo's eleven communes and accounts for a significant portion of the denomination's total production. Its vineyards are characterized by the gentler, more rolling topography typical of the western side of the Barolo zone, producing wines that have long been recognized for their aromatic complexity and relative approachability compared to the more structured expressions from communes like Serralunga d'Alba.
Terroir
The vineyards of La Morra, including Rivette, are situated on the western side of the Alba-Barolo road, which runs through the valley floor and serves as a convenient geological dividing line within the denomination. This geographic distinction is significant: the soils west of this divide differ meaningfully from those to the east, and these differences manifest clearly in the resulting wines.
La Morra's terroir is defined by calcareous marls of the Tortonian epoch, dating back approximately 7-11 million years. These soils are relatively compact and more fertile compared to the Helvetian soils found in the eastern communes of Castiglione Falletto, Monforte d'Alba, and Serralunga d'Alba, which contain a higher proportion of compressed sandstone and are generally less fertile and more austere in character.
The calcareous marl composition of La Morra has profound implications for viticulture and wine style. These clay-loam soils possess significant water-holding capacity, providing vines with more readily available moisture throughout the growing season. This characteristic influences not only vine vigor but also the ripening patterns of Nebbiolo, the notoriously late-ripening variety that forms the exclusive basis of Barolo production.
The manner in which roots navigate the complex layering of soil strata dictates the amount of water and nutrients the plant can access throughout the year. In La Morra's marly soils, this interaction tends to produce wines with more immediate aromatic expression and softer tannins compared to the iron-fisted structure typical of Serralunga or the mineral intensity of Castiglione Falletto.
Wine Characteristics
Wines from La Morra's Tortonian marls, including those from Rivette, generally express Barolo's fundamental characteristics (the haunting perfume, the high acidity, the firm tannins) but with a distinctive emphasis on aromatic complexity and relative suppleness. Depending on the specific location and exposure of the vineyard, these wines tend to be softer, fruitier, and more aromatic than their counterparts from the eastern communes.
The aromatic profile typically showcases Nebbiolo's characteristic notes of rose petal, tar, and red fruits, but often with additional floral and spice complexity. The tannins, while still substantial and requiring cellar time, are generally more polished and integrated than the more aggressive structures found in wines from sandstone-dominated sites.
Like all traditionally produced Barolo, wines from La Morra's MGAs benefit significantly from extended cellaring. The denomination's strict regulations require a minimum of 38 months of total aging before release, with at least 18 months in oak. However, the wines (particularly from top sites and producers) are structured and tannic in youth and ideally should be cellared for 10-15 years to fully resolve their tannins and develop the complex tertiary characteristics that define mature Barolo.
Context within Barolo's Classification
The introduction of the MGA system in 2010 represented a significant evolution in Barolo's wine culture. Historically, most top producers prided themselves on blending wines from multiple vineyards, searching for greater complexity through assemblage: a practice that continues among traditionalists such as Bartolo Mascarello. However, certain single vineyards had long commanded higher prices and greater prestige in both the written tradition (from Lorenzo Fantini in the late 19th century to modern authorities like Renato Ratti and Alessandro Masnaghetti) and in the oral tradition of the zone.
The MGA system formalized these distinctions without creating a hierarchical classification. The sub-zones include entire villages (such as La Morra itself), specified single vineyards, and in some cases, multiple vineyards consolidated into a single MGA designation. While the MGAs are identified as crus, they are not officially ranked, though the market and critical consensus have established clear quality hierarchies among them.
Within La Morra, Rivette takes its place among the commune's portfolio of recognized sites, contributing to the diversity of expression that makes this village such an important part of Barolo's identity. The maximum permitted yield of 56 hectoliters per hectare throughout the Barolo DOCG ensures that even lesser-known MGAs must meet the same stringent production standards as the most famous sites, maintaining the overall quality and integrity of the denomination.
