Abstract

A limited number of samples of gin and related alcoholic beverages have been analysed using high-resolution ¹H NMR Spectroscopy to investigate the effectiveness of the technique as a means of gaining insight into their chemical composition. Various types of gin were investigated, including London Dry, Compound, Old Tom, and fruit gins. The study utilized some advanced NMR experiments, including multiple solvent suppression and total correlation spectroscopy, allowing for the identification and partial quantification of constituents, including terpenes, carbohydrates, organic acids, and phenolic compounds. Overall, based on the evidence of this focused study, NMR shows great promise for the chemical analysis of gins.

Key words: Nuclear magnetic resonance spectroscopy, gin, complex mixture analysis, quantification, solvent suppression.
