The legislation of food industry is becoming increasingly strict with regard to the quality of food products. Therefore, the market\nis demanding for automatic systems of analysis that allow fast and accurate monitoring of the evolution of quality parameters in\nagrofood products or permit obtaining information to optimize production processes. In this context, sensors and more specifically\nmicrosensors play an important role since they allow fast and reproducible measurement of a large number of quality parameters\nwith good reliability and can be implemented in portable systems. This paper presents a review of the results obtained with an\nelectronic tongue based on different kinds of microsensors applied to wine analysis by the team of IMB-CNM. This multisensor\nsystem allows on one hand classifying the wine according to its features like grape variety, geographic origin, year, and organoleptic\ncharacteristics and on the other hand quantifying some parameters of interest in quality control, such as alcoholic degree, pH, ions,\ntotal acidity, glycerol, and color.
