The multiple oenological materials used in winemaking protocols have various influences on the final aromatic profile of wine. Therefore, their overall effect on a certain variety is difficult to determine, even when some of the materials are tested separately. To simplify the decision, if the winemaker would simply like to enhance the number or the concentration of the compounds forming the volatile profile of a wine, we propose in this paper a method which uses an electronic nose based on flash gas chromatographic technique to test the effect of a certain winemaking protocol. The test was made on two aromatic Romanian autochthonous varieties, Busuioaca de Bohotin and Tamâioasa românească, each vinified with 3 different winemaking protocols. The volatile profiles for each winemaking protocol and variety were recorded and compared by using multivariate statistical analysis, in order to pair the variety and protocol which can generate a more intense volatile profile.
