Abstract

Assuming horizontal differentiation and using an expanded gravity model, the main objective of this article is to assess the determinants of Portuguese wine exports. Horizontal differentiation is considered, with still and fortified wines being distinguished, as well as three distinct designations of origin: Vinho Verde, Douro, and Port wines. The results from the period between 2006 and 2016 suggest that wineries and private and public agencies should focus their commercial and policy efforts on countries with high purchasing power and/or with great potential for growth, regardless of whether the customs costs are higher. Moreover, it is concluded that horizontal differentiation influences the export determinants, suggesting there should exist different internationalization strategies for distinct types of wine.
