Currently, the wine industry has gained great relevance worldwide. At the same time, the sustainability of the business activity has positioned itself as one of the main challenges to be achieved in the coming years. Due to the great impact that agricultural processes can have on the environment, vine and wine production is particularly susceptible to the application of new technologies and processes that improve its sustainability in the medium and long term, while allowing the improvement of product quality. The main objective of this paper is to analyze the academic literature in the field of wine industry sustainability, to determine the main contributions carried out, as well as the most prominent authors, universities, and countries in this field of study. The methodology used is bibliometric analysis, specifically the Bibliometrix^® R package, in its version 4.1.1. The results reveal that research in the field of sustainability in the wine industry has increased considerably in the last three years by several leading researchers, mainly from universities located in wine-producing regions. It is concluded that research shows a trend towards collaboration among stakeholders, especially in terms of innovation, which is postulated as the main tool to improve the sustainability of the sector in the coming years.

The purpose of this research is to assess the impact of Green Human Resource Management (GHRM) on the economic, social, and environmental performance of Spanish wineries. Additionally, age, size, and Protected Designation of Origin (PDO) membership are introduced as control variables in order to increase the accuracy of the cause-effect associations examined. To reach this objective, a conceptual model has been constructed and assessed through Structural Equation Modeling (PLS-SEM) using data gathered from a survey conducted between September 2022 and January 2023, involving 196 Spanish wineries. The results demonstrate the occurrence of a positive and meaningful relationship between GHRM activities and the three yield typologies assessed in the Spanish wine context. This study is novel in the academic literature on environmental and human resource management, since, to the best of our knowledge, no previous research has looked into the effect of GHRM on the sustainable performance of Spanish wineries. Thus, it is useful for both academics and wine industry professionals who are examining potential variables that can catalyze winery performance.
