Physical-Chemical Parameters And Phenolic Compounds From Fetească Neagră Wines Aged In Different Toasted Barrels

Phenolic and Aroma Composition of White Wines Produced by Prolonged Maceration and Maturation in Wooden Barrels.

To investigate the phenolic and aroma composition of Malvazija istarska (Vitis vinifera L.) white wines produced by an unconventional technology comprising prolonged maceration followed by maturation in wooden barrels, representative samples were subjected to analysis by UV/Vis spectrometry, high-performance liquid chromatography, and gas chromatography-mass spectrometry. When compared to stand...

Organic Acids Novel Determination in Wines Aged in Oak Wood Barrels by HPLC

n this project we describe a reversed-phased HPLC method that allows the simultaneous determination of the preservatives benzoic (BA), sorbic (SA) and ascorbic acids (AA) in wine and foodstuffs. The separations were effected by using a C18 varian column and a mobile phase of ammonium acetate buffer (pH 4.4) – methanol (65:35) to elute BA, SA and AA. The flow rate was 1.0 ml/min and the detector...

Volatile compounds and sensorial characterization of wines from four Spanish denominations of origin, aged in Spanish Rebollo (Quercus pyrenaica Willd.) oak wood barrels.

The evolution of almost 40 oak-related volatile compounds and the sensorial characteristics of red wines from four Spanish denominations of origin (DOs) (Bierzo, Toro, Ribera de Duero, and Rioja) during aging in barrels made of Rebollo oak wood, Quercus pyrenaica, were studied and compared to the same wines aged in American and French oak barrels. Each oak wood added unique and special characte...
