Effect of Region on Free and Bound Monoterpene and C₁₃-Norisoprenoid Concentrations in Weisser Riesling Wines
Open accessAbstract
Free and bound monoterpene and C₁₃-norisoprenoid concentrations of Weisser Riesling wines of different vintages and from different regions in South Africa, Germany and Northern Italy were compared. The concentrations of some of these compounds differed between climatic regions. For example, older Weisser Riesling wines from South Africa displayed significantly higher 1,1,6-trimethyl-1,2-dihydronaphthalene (TDN), trans-vitispirane and trans-1,8-terpin concentrations than those from the cooler European countries. Canonical and stepwise discriminant analysis of the wine data allowed the successful classification of the wines according to origin. A comparison of meteorological data of the countries revealed that in the cooler wine regions of Germany and Northern Italy the average daily temperatures were lower, the average monthly rainfall higher and the daily sunshine hours fewer than in the warmer South African wine regions.

TDN is thought present in other wine varieties below threshold.
“It is thought that TDN is also present in other wine varieties, although at concentrations below its threshold (Etiévant 1991, Ribéreau-Gayon et al. 2000b, Marais et al. 1992, Simpson and Miller 1983).”
From Yeast and bacterial modulation of wine aroma and flavour (2005) · cites this paper as Marais et al. 1992
The Results and Discussion (p. 2) examine Weisser Riesling wines, and the Conclusions (p. 6) discuss TDN in that variety. Our copy does not say whether TDN is present in other wine varieties or whether its concentrations there are below a threshold (searched for other varieties and threshold). (LLM, conf=0.75)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
