Cantine Riunite & CIV is one of Italy's largest wine cooperatives, formed through the merger of Cantine Riunite (founded 1950) and CIV (Consorzio Interprovinciale Vini). The cooperative is headquartered in Emilia-Romagna and is best known for producing Lambrusco wines, particularly the globally popular Riunite brand which was heavily marketed in the US and internationally. The cooperative structure means it is owned by thousands of grape-growing members across the region.
