Assessing the origin of wine using existing compositional information - FA0206

Description
The UK currently lacks a system for the evaluation of wine origin by analytical methods. The aim of this project is to construct classification models that are capable of predicting the origin of wine, from minimum analytical information, defining the vintage and grape variety of a wine of a given origin with high sensitivity and satisfactory specificity. The relevant analytical data includes eighty three parameters including the levels of components such as trace and rare earth elements, organic and aromatic compounds, alcohol content and glycerol levels in addition to isotope ratios. The wine data used was previously generated during the EU/FSA Third Countries wine project (Q01063, G6RD-CT-2001-00646-WINE-DB).
Objective
The wines used in this study were from Romania, Hungary, the Czech Republic and South Africa and nine grape varieties were included. The main objectives of the project were to build models to discriminate the wines according to vintage and also according to grape variety. In order to achieve
this, all relevant data was collated in a searchable portal which was built as part of the project. A range of modelling methods, including linear and non-linear methods, were compared for sensitivity and specificity. A final objective was to report on how wine testing is performed elsewhere in Europe.
