The research project is aimed at studying the initial conditions and the role of social actors in the province of Mendoza that resulted modernization of the winemaking process. In particular, this project analyzes the R&D&I process in winegrowing in this province from the late 1960s to the early 1990s. During these years, different institutions (public and private) were generating the necessary conditions for the development of a qualitative change in the sector that took place starting in the 1990s. The objective is to analyze the technological development of the sector, who were the social actors involved; what they thought and how they carried out the changes that gave rise to a “new Argentine viticulture” and allowed it to begin to conquer international wine markets starting in the 1990s. This development allowed the sector to go from exporting 1% of its production at the beginning of the 1990s to currently reaching 20% of the country's total production. This process was not spontaneous but required significant prior development of R&D&I, the general objective of this project.
