The Eco2Wine doctoral training program, divided into ten work packages (WP) (Figure 1), encompasses wine ecology, innovation, business, and science communication. The consortium provides training in collaboration with private companies.

• WP1 is focused on studying the ecosystems and their potential in terms of microbial interactions, the main activity being ecosystem mapping. Lead by Univerza v Ljubljani (University of Ljubljana).
• WP2 focuses on defining a stable microbial consortium in winemaking-associated ecosystems. Lead by Universite Dijon Bourgogne (University of Burgundy).
• WP3 activities focus on identifying plant domestication drivers and bioprotective/control agents. Lead by Universita degli Studi di Milano (University of Milan).
• WP4, parallel with WP3, will set up spontaneous and inoculated fermentations to evaluate microbial ecology and chemical impact using reciprocal microbiome transplantation experiments. Activities will be focused on investigating specific modes of ecosystem control and their impact on interactions between species within the multispecies system. Lead by Agencia Estatal Consejo Superior de Investigaciones Cientificas (Spanish National Research Council).
• WP5 will interact closely with WP1 to define efficient marketing strategies and guidelines for microbial diversity conservation. Lead by Hochschule Geisenheim (Hochschule Geisenheim University).
• WP6, linked to WP3 and WP4, will conduct activities to develop a program for data communication at the market level. The main tasks in this WP will be focused on (i) the definition of methods/tools to bridge the gap between the scientific community and the wine stakeholders and (ii) communicating the scientific achievements of Eco2Wine. Lead by Stellenbosch University.
• WPs 7 to 10 will ensure effective coordination, management, and dissemination of the Eco2Wine project, facilitating the implementation of the research and training project activities by providing structures, tools, and procedures for monitoring and sharing the progress of the work plan and timely reporting to the European Research Executive Agency (REA). Lead by Universita degli Studi di Milano (University of Milan) (WP7), Agencia Estatal Consejo Superior de Investigaciones Cientificas (Spanish National Research Council) (WP8), Universidad de Cadiz (University of Cádiz) (WP9), Stellenbosch University (WP10).
