본 연구는 국내 주요 포도 품종인 캠벨얼리(Campbell Early)를 이용하여 발효전 원료의 전처리방법(열처리, CM처리)이 포도주 품질에 미치는 영향을 파악하고자 수행되었다. 총산에 있어서 CM처리를 할 경우 대조구나 열처리구에 비해 포도주의 총산이 낮아지는 결과를 보였다. 총안토시아닌과 탄닌 함량에 있어서, 열처리한 후 발효시킨 포도주가 대조구에 비해 높은 함량을 보인반면 CM처리의 경우는 대조구나 열처리에 비해 낮아지는 결과를 보였다.

This study was conducted to determine the influence of heating and carbonic maceration (CM) pre-treatments prior to alcohol fermentation on wine quality from the main Korean grape variety, Campbell Early. Wine fermented with CM treatment had lower total acidity than control and heated wines. Wine fermented with heat treatment contained higher concentrations of anthocyanin and tannin than control wines, while CM-treated wine had the lowest concentrations. The red coloration of the wine was highly correlated with the polyphenol content, as a high content of anthocyanin and tannin resulted in increased red color intensity. The significant differences found in wine quality as a consequence of the use of pre-treatment techniques (heating and CM treatments) suggest their potential application in wine making.
