Fig. 7From: NMR-based metabolomics in wine quality control and authenticationPCA (a) and OPLS-DA (b) score plots derived from 1H NMR spectra of healthy and botrytized (B20 and B40) base wines from 2009, indicating metabolic differences among the wines. B20 and B40 represent 20 and 40% B. cinerea infection, respectively. Reprinted with permission from Ref. [54]. Copyright (2011) American Chemical SocietyBack to article page
