Abstract

With the aid of a statistical computer program (linear discriminant analysis) based upon several monoterpene compounds, a significant analytical separation of the varieties White Riesling, Müller-Thurgau and Sylvaner of the same vintage was possible. Because of the change in the monoterpene compounds during aging of the wine, this varietal discrimination was not possible when investigating wines of several vintages. Computer evaluation of 12 commercial wines of the varieties Riesling, Müller-Thurgau and Sylvaner showed a correct prediction for 8 samples out of 12. Difficulties of the right coordination, when using this procedure, could be due to the wine law which says that - via varietal blending and addition of sweet reserve - up to 25 % of wines from other varieties can be added to a given wine without declaration.
