Thus, the need of fertilization becomes important in order to obtain desirable characteristics of grapes for wine production and high yield. Tartaric acid is considered the predominant acid in grapes and consequently in wines, also providing specific organoleptic properties.  aGrapes  aAdubação  aPotássio  aUva  aMaturação da uva  aUva Syrah  aVale do São Francisco1 aLIMA, P.
