Climate change requires a high adaptive capacity from Utiel-Requena’s winegrowers, in which institutions play an important role. This research analyzes the influence of two specific institutions, the ‘Denominación de Origen Protegida’ and the irrigation communities, on the adaptive capacity of winegrowers in Utiel-Requena. Interviews were conducted and analyzed by using the Adaptive Capacity Framework consisting of 25 indicators. Results show that both institutions scored high on equity and clear board structures. Weaknesses are the low response to winegrowers’ needs, limited knowledge transfer, and lack of clear plans for extreme situations. Both institutions did not seem to acknowledge the importance of climate change adaptation and their role in enhancing it. Overall, the sector seems to lack engagement in terms of wine quality, technical support and stakeholder communication. The results imply that the area has little climate change awareness.
