✦ Synopsis
Forty compounds were identified by gas chromatography and gas chromatography/mass spectrometry in the volatile fraction of Vernaccia di Oristano, an Italian sherry-like wine produced in Sardinia since the 1 lth century. The individual aromatic compounds were identified and quantified in the original wine, both after biological ageing by inoculation of the original wine with Sac- charomyces cerevisiae var bayanus and S cerevisiae var prostoserdovii, and after ageing under sterile conditions. The effects of flor yeasts in terms of production or subtraction of flavour components are discussed.
