This paper reports a novel application of a portable and wireless sensor system (e-nose) to differentiate, through recognition and detection of different white grape variety types, different winemaking techniques. The system is also tested to differentiate the different grape varieties in each winemaking technique combination. The analysis has been done with principal component analysis and artificial...
In this work we present the analysis and classification of different wines depending simultaneously on their denomination of origin and grape variety. We explain the array sensor system and the volatile compounds extraction method used to build the electronic nose. We also review the wine samples and their characteristics. Then with principal component analysis (PCA) we inspect the data and a probabilistic...
