This research aims to test the relation between the antecedents, barriers and consequences of adopting sustainable practices in Portuguese wine tourism companies. Quantitative research resorted to collecting primary data from 103 Portuguese wine tourism companies, the data analysis technique being structural equation modelling using SmartPLS 3.0 software. The results indicate that the antecedents (internal pressure and external pressure) influence the adoption of sustainable practices in wine tourism. In addition, the adoption of sustainable practices may result in benefits for companies in the wine tourism sector. Finally, the barriers were found not to moderate the relation between antecedents (internal pressure and external pressure) and the adoption of sustainable practices. Therefore, even if barriers are perceived by business-people, they tend to continue to adopt sustainable practices in wine tourism.
