First identification and quantification of S-3-(hexan-1-ol)-γ-glutamyl-cysteine in grape must as a potential thiol precursor, using UPLC-MS/MS analysis and stable isotope dilution assay

•Multi-step synthesis of natural and deuterated dipeptide S-conjugates.•A fast and reliable UPLC-MS/MS method for S-conjugates in must.•Formal identification of γGlutamyl-cysteine S-conjugate to 3-mercaptohexanol in must.•S-conjugates analysed in more than 200 must samples. Varietal thiols are key a...
