Piedmont

Piedmont occupies most of northwestern Italy, bordering Switzerland in the north and France in the west and almost reaching the Mediterranean coast. The tightly folded Langhe hills, which expose the Barolo and Barbaresco vineyards, are dwarfed by the snow-covered Alps to the north and west. It is a hilly region known for its fog, or nebbia, after which the Nebbiolo vine is supposedly named. According to Jancis Robinson, Nebbiolo tends to make its finest wine on the calcareous marls around Alba. The rest of the Langhe hills lie on the right bank of the Tanaro river, and the sandier soils of Roero on its left bank.

• The Alps border the region to the north and west
• Fog, or nebbia, drapes the Langhe hills in autumn, further restricting Nebbiolo's ability to ripen late in the growing season
• The Tanaro river separates the Langhe hills on its right bank from the sandier soils of Roero on its left bank
• Barolo's MASAF production rules require hillside vineyards on clay or calcareous soils between 170 and 540 m above sea level, excluding damp, flat valley floors

Barolo and Barbaresco, which Italian Wine Central calls "the twin titans" of the region, are both DOCGs made only from Nebbiolo. The Barolo zone, a few kilometres south of Alba in the province of Cuneo, takes in the whole of the communes of Barolo, Castiglione Falletto, and Serralunga d'Alba and parts of Monforte d'Alba, Novello, La Morra, Verduno, Grinzane Cavour, Diano d'Alba, Cherasco, and Roddi. Barbaresco takes in the communes of Barbaresco, Neive, and Treiso, plus part of the San Rocco Senodelvio frazione that was moved into the commune of Alba. Barbaresco tends to be very slightly lighter and earlier maturing than Barolo, from vineyards on generally warmer, lower land. Beyond Nebbiolo, the region's best-known wines include Barbera and Dolcetto reds, the white Gavi, and sparkling Asti.

• Barolo DOCG: 100% Nebbiolo, minimum 13% alcohol, and at least 38 months of aging including 18 months in wood; Riserva at least 62 months including 18 in wood
• Barbaresco DOCG: 100% Nebbiolo, minimum 12.5% alcohol, and at least 26 months of aging including 9 months in wood; Riserva at least 50 months including 9 in wood
• Barbera d'Asti, Barbera del Monferrato Superiore, and Nizza are DOCGs, while Barbera d'Alba and Barbera del Monferrato are DOCs
• The Asti DOCG covers both Asti spumante and Moscato d'Asti, made from at least 97% Moscato bianco; Moscato d'Asti is less than 6% alcohol, frizzante, and fruitily sweet

Jancis Robinson writes that, unusually for Italy, Piemonte is a wine region to which grape varieties are the key, and that its red wines depend above all on the finicky, late-ripening Nebbiolo vine, supposedly named after the fog. Nebbiolo is also early flowering, which is why it needs careful site selection away from spring frosts. Barbera is native to Piemonte, low in tannin and high in acidity, while Dolcetto is so much lower in acidity than Barbera that it tastes sweet in comparison. Muscat is the most prolific white grape, responsible for Asti and other Moscatos, while Cortese is the grape of Gavi and Arneis is known as Roero Arneis.

• Nebbiolo has been grown and valued around Alba since at least the 14th century and produces wines typically high in acidity and tannins, with aromas that can include roses, violets, woodsmoke, autumn undergrowth, and tar
• Barbera leads the primary varieties at 31%, ahead of Moscato (22%), Dolcetto (13%), and Nebbiolo (10%)
• Dolcetto, 'little sweet one', is so named because it is much lower in acidity than Barbera and tastes sweet in comparison; it will ripen on less favoured sites, even north-facing ones
• In the subalpine hills almost due north of Alba, around Gattinara, Nebbiolo is known as Spanna and makes Gattinara, Ghemme, Boca, Lessona, Bramaterra, Sizzano, and Fara, which tend to be slightly earthier and lighter-bodied; Gattinara and Ghemme are DOCGs

In its UNESCO submission for Piedmont, Italy's government said: 'Vine pollen has been found in the area dating from the 5th Century BC', adding that Piedmont was seen as one of the best vine growing areas in Italy during the Roman Empire. Barolo's MASAF production rules credit Camillo Benso, Count of Cavour, and Giulia Colbert Falletti, the last marchioness of Barolo, with beginning production, in the mid-1800s, of an exceptionally rich and harmonious wine that became the ambassador of the Savoys' Piedmont at the courts of Europe. The Barolo and Barbaresco production zones include territories first delimited by ministerial decree of 31 August 1933, and both wines were approved as DOC in 1966 and as DOCG in 1980. In 2010 the Consorzio approved the MGAs (vineyard mentions) for Barolo and Barbaresco laid out by cartographer Alessandro Masnaghetti.

• Barolo was approved as DOC by DPR of 23 April 1966 and as DOCG by DPR of 1 July 1980; Barbaresco as DOC by DPR of 23 April 1966 and as DOCG by DPR of 3 October 1980
• Barolo has 181 menzioni geografiche aggiuntive, including 11 commune names, and Barbaresco has 66
• French barriques imported in the 1970s and 1980s caused some revision of wine styles, and producers today use a mixture of barriques and larger oak containers

Piedmont produced 2.4 million hl (26.8 million cases) in 2022, slightly below average, leaning 60-40 toward red wines and with 94% at the DOP level. It had 43,536 ha (107,500 acres) of vineyards registered in 2022. The region has 19 DOCGs and 41 DOCs and no IGPs. On June 22, 2014, UNESCO added the Vineyard Landscape of Piedmont: Langhe-Roero and Monferrato to its World Heritage list; the site includes the Barolo DOCG communes of Barolo, Castiglione Falletto, Grinzane Cavour, La Morra, Monforte d'Alba, Novello, and Serralunga d'Alba and the Barbaresco DOCG communes of Barbaresco and Neive.

• 2.4 million hl produced in 2022, leaning 60-40 toward red, with 94% at the DOP level
• Barolo DOCG: 2,057 ha of vineyard in 2021 and 106,600 hl of production as a five-year average; Barbaresco DOCG: 712 ha in 2021 and 32,800 hl
• No IGPs; 19 DOCGs and 41 DOCs
• UNESCO World Heritage listing of the Vineyard Landscape of Piedmont: Langhe-Roero and Monferrato on June 22, 2014
