| This report has investigated the seasonal temperatures influences (winter and summer) of five vineyards at different altitudes on the concentrations of 2-methoxy-3-isobutylpyrazine (MIBP), a- and ß-ionone, and ß-damascenone in 2004 or 2005 vintages of Cabernet Sauvignon wines from Santa Catarina State, Brazil. Sensorial analyses were also carried out on the wine samples and compared to altitude and climate. Significant regression was observed between MIBP concentrations and the vineyard's altitude. No significant relation was observed between a- and ß-ionone and ß-damascenone with the vineyard's altitude. Principal component analysis positively correlated wines from higher altitudes with a bell pepper aroma. Conversely, the wines made with grapes from... |
