In the same year, the following variables were determined: density, alcohol, titratable acidity, volatile acidity, fixed acidity, pH, dry extract, reducing sugars, reduced dry extract, alcohol in weight/reduced dry extract, ashes, alkalinity of ashes, absorbance--420 nm (I 420) and 520 nm (I 520)--, color intensity (I 420 + I 520), hue (I 420/I 520), anthocyanins, tannins, total polyphenols index, volatile compounds--ethyl acetate, methanol, 1-propanol, 2-methyl-1-propanol, 2-methyl-1-butanol + 3-methyl-1-butanol and sum of higher alcohols.
Ethyl acetate, ethyl hexanoate, ethyl octanoate, 2-methyl1-butanol, 3-methyl-1-butanol, 1-hexanol, 1-octanol, phenylethyl alcohol, and hexanoic acid were positively identified by comparing the spectra and chromatographic peak RIs of samples and analytical standards.
The straight-chain higher alcohols are considered to have the most significant sensorial impact (1-propanol, 2-methyl-1-propanol (isobutyl alcohol), 2-methyl-1-butanol and 3-methyl-1-butanol (isoamyl alcohol).
