Barbera d'Asti is an Italian red wine made from the Barbera grape variety. It is produced in the hilly areas of the provinces of Asti (67 municipalities) and Alexandria (51 municipalities). Barbera d'Asti was accredited with DOC status in 1970, and DOCG status followed in 2008.
The wine must be made before the date of 1 March immediately following the harvest, and must reach an alcohol content of 11.5%.
Since 2000, it has been possible to produce Barbera d'Asti Superiore, for which the wine must have an alcoholic strength of at least 12.5% by volume, and be aged for at least 14 months, 6 months of which stored in oak or chestnut barrels. Many superiore producers refine it in small oak barriques to obtain a rounder taste. The superiore has the following sub-zones indicated on the label: Nizza, Tinella, or Colli Astiani (Asti).
The superiore wine has a strong additional aging potential; it can often be aged from ten to twenty years.
The Nizza DOCG was added to Asti's Barbera portfolio in 2014. The 'Nizza' production rules require the use of 100% Barbera grapes, a maximum yield of 7 tonnes per hectare, and minimum aging of 18 months, of which 6 months must be in oak barrels. The minimum alcoholic strength is 13%, or 13.5% if produced by a single, named vineyard.
The Barbera grape is believed to have originated in the hills of Monferrato in central Piedmont, Italy and is known from the thirteenth century. The first written proof of vinification is stored in the city hall of Nizza Monferrato and dates back to the seventeenth century. The wine enters officially in the roll of Piedmontese wines in 1798, the date of the first Ampelography made by Giuseppe Nuvolone-Pergamo, count of Scandaluzza from the Società Agraria di Torino (Agricultural Society of Turin).
Barbera spread rapidly in the 19th and 20th centuries, and is today considered to be Piedmont's principal red grape variety.
