Characteristics of aroma compounds of 11 red wines from international grape cultivars grown in Korea

Abstract

The aroma compounds of 11 red wines grown and produced in Wanju region were characterized by headspace-solid phase microextraction combined with gas chromatography-mass spectrometry. Seventy-five aroma compounds were identified in the 11 red wines. The aroma compounds were grouped into five aroma series and their odor activity values were calculated to determine the aroma impact compounds in 11 wines. Alcohols, esters and C6compounds were the main contributors to the aroma in the 11 wines. Isoamyl alcohol and phenylethyl alcohol obtained from the 11 red wines contributed to the floral, sweet, and fatty odorants in the wine. Octanoic acid ethyl ester, and hexanoic acid ethyl ester contributed to the fruity, floral, and sweet odorants of all the red wines. 1-Hexanol was detected all the wines, which contributed to the green odorant. The major aroma contribution of Chanceller, Malbec, Marchel, Narsha, Pinot Meunier, and Sangiovetto wines were the fruity series. The green series was the major contribution of the Cabernet Franc, Cabernet Sauvignon, and Sauvignon Vert wines. The floral series was the major contribution of the MBA and Narsha wines. Based on the results of these studies, aroma component analysis could be used as a selection criterion for developing wine cultivars.
