Claudia is from Germany where she completed her undergraduate degree in Food Chemistry (Westphalian Wilhelms University, Muenster). She came to Otago to experience a different culture, explore New Zealand’s beautiful countryside and to learn to speak English fluently while doing her PhD.
Mt. Difficulty Wines (Central Otago, NZ) has 3 vineyard sites that tend to produce single vineyard Pinot Noir wines with higher typicity (grape variety character) than wines from other sites. In order to gain a better understanding of why these sites produce high typicity wine, the study compares the volatile and non-volatile profiles of commercially produced grape derived products (grape juices, fermenting and fermented wines as well as the wines from barrels) from 6 vineyard sites, including 3 high typicity expressing sites, and 8 grapevine clone mixtures. Methodologies used for the analyses are PTR-MS and GC-MS for the volatile profiles and 1H-NMR (metabolic profile) and front-face fluorescence (phenolic profile). The data analysis methodologies used are ANOVA, PCA, MFA, PARAFAC, PARAFAC2, ASCA and PLS-DA (software: MATLAB, R, SPSS, Unscrambler, MestReNova, MetAlign).
