dc.descriptionTropical wines have been produced in Thailand, India, Venezuela and mainly in Northeastem Brazil. In Brazil, this activity started twenty-five years ago and has been studied only in the last years. In this Brazilian Area, between 8_90 parallel of the South Hemisphere, it is possible to have two or three harvests per year due to the high temperatures (annual average temperature of 26 "C), high luminosity and use of irrigation. Analytical composition of grapes and wines can vary strongly according to harvest date into a year, (wines elaborated in the first or second semester). The aim of this work was to determine metabolic fingerprints of white and red wines from two vintages of 2009, according to their aromatic profile, using gas chromatographyand multivariate statistical analyses. Wines were elaborated by traditional methods, in stainless steel tanks of 200 L, by controlling fermentations temperature for red and white wines and using antioxidants. After stabilization and bottling, wines were analyzed in triplicate using gas chromatography with flame ionization detecto r (OC-FID). PCA multivariate statistical analysis was applied on aromatic compounds data to discriminate between wine type and month of winemaking, and different clustering were formed. White and red tropical wines presented different aromatic compound concentrations; higher alcohols were more efficient to separate wine samples than volatile esters.pt_BR
