The applicability of stable isotope analysis to assign the geographic origin of distilled beverages has been investigated using Schwarzwälder Kirsch", i.e., a cherry brandy from the Black Forest area in Germany, as an example. Isotope ratios were determined in authentic cherry mashes as well as in cherry brandies provided by distillers from specified locations. Analysis of distillate fractions revealed that distillations in a pot still proceed with vapor pressure isotope effects for the carbon and the hydrogen isotopologues of ethanol. It could be demonstrated that these isotope fractionations do not impair the applicability of stable isotope analysis for the authenticity assessment of cherry brandies. The first data sets from two vintages indicate that, in principle, an assignment of the origin of cherry brandies on the basis of stable isotope data is possible. However, multi-element analysis in combination with efficient statistical methods is required.
