Analysis of the collaboration between the US and the EU in viticulture and oenology

The network of scientific collaboration in viticulture and oenology between the United States and the European Union was studied for the period 1991-2010. A total of 498 articles were published collaboratively during this time. The most collaborative institutions in the US were the University of California Davis and Cornell University (New York), and the most collaborative institutions in the EU were Institut Nationale de la Recherche Agronomique (France), the Italian universities of Milan, Bologna and Udine, and the Spanish University of Barcelona. We note a considerable increase in collaboration in recent years, with the University of California Davis situated in a central position in the network. --Keywords: biblometric indicators, collaboration networks, European Union, scientific publications, United States of America, viticulture and oenology research--
