A systematic review of consumer research on dealcoholized wines: reviewing the evidence, shaping the future of research

In response to the growing global focus on healthier lifestyles and reduced alcohol consumption, dealcoholized wines, including both No- and Low-alcohol (NoLo) wines, are emerging as a key innovation within the wine industry. However, existing literature reviews remain fragmented, outdated, or limited, lacking an integrated overview of consumer research on NoLo wines. This study addresses this gap by presenting the first comprehensive and up-to-date systematic literature review dedicated specifically to consumer-focused research on NoLo wines. Peer-reviewed studies published up to mid-2025 were retrieved from major academic databases and selected through a methodologically rigorous process based on the PRISMA protocol and the SPICE framework. To explore the conceptual landscape and evolution of this research area, a bibliometric network analysis was conducted using VOSviewer and the Bibliometrix R package, identifying key authors and emerging thematic patterns in the literature. Moreover, the review synthesizes and discusses the literature across 12 interrelated thematic areas (e.g., health considerations, consumer perception, acceptance and preference, perceived quality, motivational factors and barriers, cultural and religious values, overcompensation, sustainability, etc.), thereby providing a state-of-the-art picture. The study concludes by identifying key priorities for future consumer research and advocating for multidisciplinary and cross-cultural approaches. These are essential to help scholars, industry stakeholders, and policymakers deepen understanding, drive innovation, and develop strategies that foster wider consumer acceptance of NoLo wines in this rapidly evolving market.
