Making wine, selling grapes, or delivering to a cooperative? Determinants of grape allocation

A typical characteristic of the wine supply chain in the Old World is the significant share of cooperatives in wine-making that coexists with investor-owned firms and on-farm wine-makers. This paper analyzes the determinants of whether grape growers deliver their grapes to a cooperative winery of which they are members, sell their grapes to outside wineries, or make their own wine on their farm. Our analysis is based on data from a typical wine-producing area in Northern Italy. The explanatory variables comprise the potential prices linked to the different grape allocations and various farmer and farm characteristics. The high share of farmers delivering their grapes to cooperatives can, to a large extent, be explained by their higher price relative to one of the spot markets. On-farm wine-making is favored by larger farms and more educated farmers
