| Abstract: | "This study investigated the effect of vineyard site on the volatile profiles of Pinot Noir wines using proton-transfer reaction mass spectrometry with prior headspace dilution. The ANOVA and PCA enabled discrimination of wine based on vineyard site. Sample separation was due to differences in the ratios of a mixture of compounds, including higher alcohols, ethyl, and acetate esters. Proton-transfer reaction mass spectrometry appears to be a useful technique for rapidly discriminating wines based on vineyard site. The similarities and differences expressed in the wines' volatile profiles may help winemakers to reveal the potential of individual vineyard sites to produce wines of certain character.
