This essay proposes terroir as a metaphor for rethinking science communication. In contrast to dominant calls for a science of science communication, grounded in broadly replicable and generalisable methods, we suggest that communication practices are fundamentally shaped by the particularities of place, people, histories, and more-than-human relations. Drawing on the agricultural origins of terroir, we argue that good science communication is not about imposing control but about cultivating resonance within specific ecosystems of meaning. This perspective also invites us to recognise the value of intuitive knowledge, local practice, and arts-based methods, which are often excluded from dominant frameworks. As part of the research programme Addressing Sustainability with Arts-Based Science Communication, we explore co-creative, arts-based approaches that surface emotional, sensory, and contextual dimensions of sustainability science communication. Ultimately, we call for a shift: from the search for universal best practices to the careful, situated crafting of an arts of science communication.
