The potential of wine 13C isotope composition (δ13C) is presented to assess vine water status during grape ripening. Measurements of δ13C have been performed on a set of 32 authentic wines and their ethanol recovered after distillation. The data, obtained by isotope ratio monitoring by mass spectrometry coupled to an elemental analyser (irm-EA/MS), show a high correlation between δ13C of the bulk...
