Nowadays, the relationships among wine tourism and environmental and economic sustainability has gained an outstanding importance on the supply side because of changes in wine visits’ demand and behaviour. This paper aims to better understand the model which explains the number of wine visits wherever product and landscape management are considered key factors for the wine tourism development of the Conegliano Valdobbiadene Prosecco PDO. In order to assess the research questions, we used the method of instrumental variables (IV), applied through the Two-Stages Least Squares (TSLS) procedure for evaluating wineries sustainability’s policies towards winery visits. Results showed how in the case of the Conegliano Valdobbiadene Prosecco PDO’s wineries, evidence-based strategies on product and landscape sustainability policies should be taken into account when managing more effective visits experiences.
