• Resumen

  • This paper describes 23 commercial Italian wines, made from organic grapes, by their chemical parameters, biologically active polyphenol concentrations and sensory analysis. Our data show inconsistent differences in the trans-resveratrol and p-coumaric acid contents in comparison with non-organic wine, with the exception of quercetin concentrations in Chianti samples. Furthermore, the chemical analyses and sensory data of organic wines did not significantly differ from those previously cited. In general the organic wines display satisfactory sensory properties such as flavour intensity, body and a general acceptance.
