Purpose: The purpose of this study is to focus on analyzing how the set of green intangibles held by wineries and their members, i.e. green intellectual capital (GIC), affects green innovation performance (GIP). Specifically, the study aims to investigate how GIP is influenced by GIC through the mediating role of the variable knowledge management (KM) and corporate social responsibility (CSR).Design/methodology/approach: The study proposes a conceptual model, based on previous studies, which is tested through structural equations (PLS-SEM) with data collected from 202 Spanish wineries.Findings: The results of the research indicate that there is a positive and significant relationship between GIC and GIP. Furthermore, CSR and KM partially mediate the relationship between these two variables, playing a key role in the environmental management of wineries.Originality/value: The present research, therefore, contributes to the literature in several ways. First, the study advances the understanding of GIC as well as its link with GIP. Second, the research aims to fill the gap in the literature through the study of CSR and KM as mediating variables in such a link. Third, to the best of the authors’ knowledge, the model proposed has not been previously addressed in the academic literature, thus representing an advance in scientific knowledge. Fourthly, no research has addressed the study of environmental intangibles in the wine industry, with this research, therefore, being a pioneer in contextualizing the study of GIC in this increasingly knowledge-intensive industry.

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.

Winemaking is an ancestral activity characterized by its strong roots in the culture, heritage, and people of the producing regions. In addition to providing important health benefits, wine is a product that is widely accepted by society. However, the socioeconomic context is evolving at a rapid pace, and new requirements and needs are forcing companies to innovate in order to remain competitive in the markets, especially in terms of sustainability. The main aim of this paper is to analyze the relationship between green transformational leadership and green innovation, as well as the mediating effect of green motivation and green creativity in this relationship. Data were obtained from a sample of 196 Spanish companies belonging to the wine industry and, as a method of analysis, was used partial least squares structural equation modeling PLS-SEM. The results show a positive and significant relationship between green transformational leadership and green innovation in wine companies. Furthermore, green motivation and green creativity exert a mediating effect in this relationship. It is concluded that the managers of wine companies should encourage employee motivation and creativity, especially in ecological terms, by creating an environment conducive to the development of environmentally friendly innovations.

This research offers a bibliometric analysis of 588 publications on wine tourism published between 1998 and 2021, highlighting the years of publication, the publication format, the fields of research, the authors, the institutions, the main journals and the country of origin of both the authors and the scientific production analyzed. To our knowledge, no bibliometric study has focused on the study of wine tourism, so this study aims to fill this research gap, serving as a reference guide for both academics and professionals in the wine sector who want to know in depth how the study of this type of tourism has been approached. The results of the research show that the academic study of wine tourism dates back to the end of the 1990s, with the New World countries standing out in its study, especially Australia as the country with the highest scientific production and the largest number of academics focused on the study of this type of tourism. The study allows us to highlight the value of academic articles as the main means of disseminating research results, these being focused on tourism, business, economic and cross-cutting research. The results reveal relevant conclusions for academics, winemakers and tourism managers on the knowledge structure of wine tourism activity.

Purpose: This research focuses on analyzing the impact of Green Intellectual Capital (GIC) on the Environmental Performance (EP) of Spanish wineries, as well as the mediating effect of Green Ambidexterity Innovation (GAI) on the main relationship posed (GIC–EP), and the moderating effect of Top Management Environmental Awareness (TMEA) on the GAI–EP link. In addition, age, size and size and membership in a Protected Designation of Origin (PDO) to increase the accuracy of the cause–effect relationships examined.Design/methodology/approach: The study proposes a conceptual model based on previous studies, which is tested using structural equations (PLS-SEM) with data collected from 196 Spanish wineries between September 2022 and January 2023.Findings: The results of the research reveal the existence of a positive and significant relationship between the development of GIC and EP of Spanish wineries, as well as the partial mediation of GAI in this link and the positive moderation of TMEA in the GAI–EP relationship.Originality/value: The originality of the study is explained by several factors. First, the study pioneered the exploration of TMEA as a moderator of the relationship between GAI and EP, allowing such analysis to improve understanding of the dynamic interaction between innovation and environmental management. Second, to the best of the authors' knowledge, there are no preceding studies that have previously proposed the theoretical model presented in this research, thus providing new scientific knowledge on the intellectual capital field. Third, the contextualization of the study in the wine sector, traditionally perceived as little knowledge-intensive, contributes significantly to the existing body of scientific knowledge on the environmental management of wineries, given that it allows the identification of the catalysing variables of EP in the Spanish wine context.
