[j] .酿酒研究，2011,31(3),215-229,2010 .通过将可疑样品的分析数据与正品威士忌的分析范围进行比较，可以确定特定品牌苏格兰威士忌的真伪。当一个产品声称是苏格兰威士忌时，根据苏格兰威士忌的法律定义，它不是在苏格兰生产的，存在更广泛的通用真实性问题。当此类案件进入诉讼阶段时，法院可能会要求化学家分析可疑产品并得出真伪结论。本文介绍了从麦芽，谷物和混合苏格兰威士忌的调查中产生的分析概况，并将结果与其他来源的威士忌和声称是苏格兰威士忌的各种可疑产品的例子进行比较。主要挥发性化合物（或同源物）的浓度和浓度比，特别是甲醇、正丙醇、异丁醇和2-甲基丁醇和3-甲基丁醇的浓度和浓度比，被发现是真实性决策过程中的重要因素。此外，缺乏已知的苏格兰威士忌同源物，已知存在的化合物不存在于真正的威士忌和异常的成熟同源物档案都有助于决策过程。从这个审查真正的分析概况，一个实验方案，以确定苏格兰威士忌的真实性提出。
J. Inst. Brew. 116(3), 215-229, 2010The authenticity of a specific brand of Scotch whisky may be confirmed by comparing analytical data for suspect samples with reference to analytical ranges for the genuine brand. Wider generic authenticity issues exist when a product purports to be Scotch whisky when it has not been produced in Scotland in accordance with the legal definition of Scotch whisky. When such cases reach litigation, courts may ask chemists to analyse suspect products and draw conclusions on authenticity. This paper presents analytical profiles generated from a survey of Malt, Grain and Blended Scotch whiskies and compares the results with whiskies of other origins and examples of a diverse range of suspect products purporting to be Scotch whisky. The concentrations and ratios of concentrations of the major volatile compounds (or congeners), particularly methanol, n-propanol, isobutanol and 2- and 3-methyl butanol, were found to be important factors in the authenticity decision-making process. In addition, the absence of known Scotch whisky congeners, the presence of compounds known to be absent from genuine whisky and abnormal maturation congener profiles all contributed to the decision process. From this review of genuine analytical profiles, an experimental protocol for determining the authenticity of Scotch whisky is proposed.
