Red grape variety originating from Italy. Well-known appellations include Barbera d'Alba DOC and Barbera d'Asti DOCG in the Piedmont. Barbera is mostly used to produce single-varietal red wines (though technically certain other red grapes can be added to the assemblage to a minor extent in most appellations) with a red fruit aroma and flavour, medium to high acidity and low to medium tannins. Some producers choose to mature their wines in barrique to give them more depth and complexity.
