: Viticulture, the cultivation of grapes, is undergoing significant transformation through the adoption of Internet ofThings (IoT)-enabled automated monitoring systems. This review systematically synthesizes current research and practicalapplications of IoT in viticulture, focusing on their impact on grape yield, quality, and resource management. The studyoutlines the theoretical foundations of IoT in agriculture, highlighting the role of interconnected sensors, devices, and digitalplatforms in real-time data collection, analysis, and decision-making. Applications in viticulture include smart irrigation,disease and pest monitoring, soil and canopy analysis, and supply chain traceability, all contributing to precision agricultureand sustainability. Case studies from major wine-producing regions demonstrate that IoT systems support continuousmonitoring of critical parameters-such as soil moisture, nutrient levels, and microclimate-enabling data-driven interventionsthat optimize resource use and improve grape quality. Automated monitoring platforms have shown to increase grape yieldsby up to 153%, reduce water consumption by 33%, and decrease fungicide use by 60%, while also lowering production costsby 20-30%. Despite these benefits, implementation faces challenges related to digital infrastructure, interoperability,organizational readiness, and policy frameworks. Overcoming these barriers requires strategic planning, stakeholdercollaboration, investment in training, and supportive policies. The review identifies research gaps in big data integration,open innovation, and the development of managerial and organizational capacities for digital transformation in viticulture.Future directions include empirical validation of IoT frameworks, development of standardized performance indicators, andexploration of ethical and regulatory issues. Overall, the integration of IoT technologies in viticulture offers substantialopportunities for enhancing sustainability, efficiency, and competitiveness in the grape sector, provided that technical,organizational, and policy challenges are systematically addressed.Keywords: Viticulture, Internet of Things (IoT), Automated monitoring systems, Precision agriculture, Grape yield
