초록

This study was carried out to evaluate the quality characteristics of Korean domestic commercial white wines. Four sample wines were analyzed in terms of their pH, total acidity, volatile acidity, alcohol content, soluble solid, free SO2, total SO2, color, free sugar content, organic acid, volatile compounds, total polyphenol content, DPPH radical scavenging activity and sensory characteristics. The pH of wines ranged from 3.06 to 3.76 and their total acidity from 0.43 to 0.83% (v/v). The alcohol content of samples ranged from 9.4 to 12.8% (v/v) and their soluble solid contents from 9.9 to 12.3 °Brix. The free SO2 and total SO2 contents of the W1 wine were lower than those of the other wines, while the color intensity, a (redness) and b (yellowness) of W1 wine were higher than the values of the other wines. The malic acid contents of the four wines indicated that complete malolactic fermentation (MLF) occurred in W1, incomplete MLF in W3, and was absent in W2 and W4. Aroma analysis resulted in identification of 10 alcohols, 11 esters, 2 ketones and 6 miscellaneous compounds. 2,3-Epoxybutane and 1-(ethenyloxy)-pentane levels in were significantly higher W1 than the other wines, while several types of ester predominated in W2, W3 and W4. W1 had the lowest sensory score among the four wines. Therefore, the quality characteristics of domestic white wines are considered to be acceptable.
