Excitation-Emission Matrix (EEM) Fluorescence has recently become a more common tool for the analysis of wines.  In particular, information from the wine spectra can be used forensically to determine the grape varietal and growing region.  Our study used EEM to investigate over 40 white wines that includes several varietals from five countries.  A unique feature of our study is that it included American wines from a multitude of geographic regions.  Specifically, rieslings from the West Coast, East Coast, and Midwest were included in the data set.  The fluorimetric data was processed with both principal component analysis (PCA) and parallel factor analysis (PARAFAC).  The two statistical analyses from the EEM data gave complementary information, but both showed potential for use in wine characterization.<br/>
