The enantiomeric ratios of chiral volatile organic compounds in juniper‐flavored spirits produced by various processing technologies in different EU countries were determined by multidimensional GC using solid‐phase microextraction and liquid–liquid extraction as a sample pretreatment procedure. In total, more than 260 compounds were detected in studied spirits from which linalool, α‐terpineol, 4‐terpineol, linalool oxides, α‐pinene, and verbenone were selected for enantiomeric separation. The significant differences in enantiomeric ratio of linalool and cis ‐linalool oxide allowed us to distinguish between samples produced in Slovakia and the United Kingdom from those produced in Germany, Czech Republic, and Belgium. The pure enantiomer of trans ‐linalool oxide was found only in samples from Germany. It was shown that the enantiomeric ratio is independent of the sample treatment procedure, and only small differences up to 1% were observed.
