Abstract
Proton and carbon-13 nuclear magnetic resonance (NMR) spectroscopic me thods were applied in the differentiation of 53 German white wines fro m the regions Rheinhessen, Rheingau and Mosel-Saar-Ruwer. The robustne ss of these differentiations was tested by leaving out one sample at a time and replacing it into the set as a test sample. Small variations in the position of the lines in the spectra, which lowered the classi fication ability of the tested systems, were successfully eliminated u sing a novel data pre-processing algorithm called partial linear fit.
