DOCG area for red wine in the Italian region of Piedmont. The former subzone of the Barbera d'Asti DOCG area became independent in 2014. Until then this wine was produced under the designation Barbera d'Asti Superiore Nizza. The zone includes the 18 municipalities of Agliano Terme, Belveglio, Bruno, Calamandrana, Castel Boglione, Castelnuovo Belbo, Castelnuovo Calcea, Castel Rocchero, Cortiglione, Incisa Scapaccino, Moasca, Mombaruzzo, Mombercelli, Nizza Monferrato, Rocchetta Palafea, San Marzano Oliveto, Vaglio Serra and Vinchio. The vineyards cover about 250 hectares and are mostly situated between 100 and 400 metres above sea level. In the case of classified vineyards, Vigna followed by the name of the vineyard may be indicated on the label. The wine must be made from 100% Barbera. The alcohol content must be at least 13% vol. or 13.5% vol. if Vigna is used. The ageing period is 14 months, of which at least 6 in cask. After 30 months of ageing, of which at least 12 months in the barrel, it may call itself Riserva.
There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.Sigi Hiss
