Piemonte is one of the most highly regarded Italian wine regions, a reputation due, in large part, to the stellar wines produced in its Langhe sub-region. The Langhe (tongues of land) is separated from the Roero sub-region by the Tanaro River and is characterized by long, steep-sided hill slopes that are separated one from the other by a series of narrow valleys.
The climate in the Langhe is continental with warm Mediterranean air from the Ligurian Sea moderating somewhat the effects of cold air coming off the Alps to the north. Weather varies from year to year resulting in appreciable vintage variation. Hailstorms are an appreciable risk with the potential for associated crop loss.
When the Padano Sea retreated from what is today's Langhe, it left behind layers of clay, calcareaous marl, blue marl, tufa, sand, and sulfur-bearing chalk. This soil is credited with bestowing structure and finesse on the areas full-bodied reds.
The primary grape varieties grown in Langhe are shown in the table below.
Nebbiolo, the variety used in the region's famed Barolo and Barbaresco wines, is considered Italy's most noble grape. Its name is thought to derive from the Italian word for fog, a condition which is common in Barolo during the September-October maturation period of the variety. The grape requires the warmest sites in order to ensure full ripening. There is significantly more Barbera planted in Langhe than Nebbiolo. This variety is vigorous, high in acid, and resistant to fungal disease and its retiring aroma (plus acidity) renders it an excellent blending wine. When cropped for quality this grape can show aromas of red fruits, currants, and blackberries. Dolcetto -- the little sweet one -- is an early ripening variety which is low in acid but high in tannins. It is however, considered much more approachable than its rich cousins and serves as the everyday drinking wine of the Piedmontese. This variety is characterized by aromas of ripe blackberries and plums. Moscato Bianco is a white grape that is the fourth most planted variety in Italy. Known by a number of names, the resulting wines tend to be fizzy or sparkling and produce aromas of lychee and rose petals.
Barolo wines are produced from Nebbiolo grapes grown on the hillsides to the southwest of Alba in five key communes and parts of five sub-zones. The soils around the towns of Barolo and La Morra are composed of a limestone-rich marl -- referred to as Tortonian -- that yields aromatic and elegant wines. The wines from the Barolo commune are thought to be more complex, and broader in texture, than the more perfumed and graceful La Morra wines. The Helvetian soil around the remaining Barolo-qualified communes is chalky and less fertile than its Tortonian counterpart and produces a wine that is more structured and requires longer ageing. Barolo wines are distinguished by aromas of tar and roses when young, evolving to earth, truffles, and dark chocolate with the passage of time. Barolo attained its DOCG status in 1980.
Serralunga d'Alba is a small, medieval village in the Langhe region of Piedmont that is 7100 meters long, 1800 meters wide at its widest point, sits on a hill 414 meters above sea level, and serves as the eastern flank of the Barolo wine production zone. According to massolini.it, Serralunga d'Alba is one of only three of the 11 Barolo communes that are contained in their entirety within the production zone (the remaining two are Barolo and Castiglione Falletto).
According to Gambero Rosso (Serralunga Barolo: The unrushable wine; gamberorosso.it), Serralunga d'Alba has "compact, sandstone-based soils dating from the Helvetian period." These soils are high in sand, limestone, iron, phosphorous, and potassium and, as a result, produce wines that are intense and structured and that need time to mature.

Barbaresco wines are produced from grapes grown on the steep, pre-alpine hillsides of four small villages located to the northeast of Alba. The grapes are grown on limestone rich marl soils on south-facing exposures with elevation in excess of 200 meters. The climate in the Barbaresco growing area is warmer and drier than in Barolo, allowing the grapes to ripen earlier and the resulting wines to be less tannic and more approachable. Barbaresco wines are known for their rich, spicy flavors and perfumed sweetness.
