VOLATILE COMPOUNDS IDENTIFIED AND QUANTIFIED IN MOLDOVA’S WINES

Abstract:

In this paper we studied and characterized four wines from the grape varieties Busuioaca de Bohotin, Feteasca neagră, Muscat Ottonel, Pinot gris, harvests of 2016, 2017, 2018, coming from the: Bohotin, Cotești, Cotnari, Huși and Iasi vineyards. The GC-MS methods were utilized to identifing and quantifing the volatile compounds of thies wines.The results obtained being grouped into three categories, namely: higher alcohols, volatile acids and esters. It was found that the higher alcohols have minimum values between 195.07 mg / L and maximum values of 257.2 mg / L in Huși and Bohotin for Feteascea black wine, the volatile acids do not exceed 17.92 mg / L in Cotnari in Muscat wine Ottonel and the esters reach values of 204.78 mg / L at the Cotești vineyard in the case of Fetească neagră wine. From the results obtained we distinguish the Feteasca neagră wine with the optimal ratio between the three monitored indicators.
