Costigliole d'Asti (Piedmontese: Costiòle d'Ast) is a small Italian town in the Province of Asti, southern Piedmont. It lies about 13 kilometres (8 miles) south of the city of Asti in the Alto Monferrato, on the edge of the Langhe, in the alluvial plain of the river Tanaro southwards into the hills. The name derives from the Latin Corte Costeliolae.
Costigliole d'Asti is particularly known for its viticulture. Its vineyards, which cover an area of more than 11.75 square kilometres (4.54 sq mi), are the most extensive of any Piedmontese commune.[4][5]
