The demand for reliable, rapid, and low-cost tools for quality control analysis has driven the development and application of different instrumental approaches in the wine industry. Thus, this review aims to gather and discuss the most relevant analytical methodologies reported in the literature, with emphasis on spectroscopic, chromatographic, electroanalytical, and sensor-based techniques, including electronic noses and tongues, as well as the integration of these techniques with chemometric tools. The studied methods demonstrate, in varying levels of precision, the potential for determining chemical composition, detecting contaminants and adulterations, evaluating attributes related to sensory quality, and monitoring fermentation and aging processes. Advances in non-destructive methods with high analytical throughput are highlighted, as these approaches have gained relevance due to their applicability in routine analyses which is desired for process control. Despite the progress observed, challenges related to sensitivity, selectivity, matrix effects, and method standardization still persist, limiting their industrial implementation. Finally, this review identifies research gaps, therefore pointing to perspectives for the development of standardization routines for the different methodologies, and the integration of analytical methods in the decision-making framework of the winemaking industry.
