This chapter examines the policy implications of wine tourism development from a territorially grounded and producer-centered perspective, drawing on the comparative analysis of Rioja and Mendoza. The findings highlight that wine tourism cannot be governed effectively through generic tourism or agricultural policies, as its strategic meaning emerges from region-specific combinations of historical trajectories, environmental conditions, and institutional frameworks. In Rioja, wine tourism is embedded in a dense system of symbolic legitimacy, aging culture, and regulatory stability, requiring governance approaches that prioritize heritage protection, spatial coherence, and controlled experiential innovation. In Mendoza, by contrast, wine tourism operates as a tool for international positioning and economic diversification, closely tied to altitude, irrigation governance, and environmental visibility, which calls for policies centered on water management, climate adaptation, and landscape integrity. Across both regions, the analysis shows that policy effectiveness depends on recognizing wine tourism as a cross-sectoral territorial field rather than as an ancillary activity. The chapter argues for governance frameworks that integrate agricultural, environmental, cultural, and tourism planning, avoid template-based policy transfer, and adopt evaluation criteria aligned with region-specific definitions of success. By aligning public intervention with the strategic logics articulated by producers, regional authorities can support wine tourism models that are economically viable, environmentally resilient, and culturally coherent over the long term.
