PHENOLIC COMPARISON BETWEEN COLOMBIAN RED WINES AND THOSE IMPORTED
Keywords:red wine, anthocyans, tanines,
The phenolic compounds play an important role in the quality of red wines. They give sensorial
characteristics like flavor, aroma, color, astringency, among others. In this study seven (7) red wines on
the market were analyzed from different geographic origins of which the total index of polyphenols
(IPT) was to be determined; also, to determine the quantity of tanines, quantity of Anthocyans and the
chromatic characteristic. In the IPT analysis among all the wines a similar effect was produced without
considering origin. The Colombian wines presented low values in the content of tanines and anthocyans
lower than in the international wines. While all the wines present a medium value of color intensity of
the chromatic characteristic, the Colombian wines showed less value. In so far as tone is concerned, the
Colombian wines are similar to the international ones. According to the obtained results it is possible
to be concluded that the IPT in all the wines is similar and that they are in the normal rank of a young
red wine. Also it happens the same to the chromatic characteristics. Whereas the content of tanines and
anthocyans Colombian wines they are lower than in the mattered.
