Abstract
This study aimed to investigate the wine properties of new Korean grape cultivar Ageude. To this end, wine was produced using five grape cultivars including Campbell Early and Muscat Bailey A, which are commonly used for winemaking in Korea and Pinot Meunier and Gamay, which are European wine grape cultivars. We conducted a comprehensive analysis of wine quality properties, color, and phenolic compounds and compared the variations observed among these cultivars. The pH and total acid contents were in the ranges of 3.75-4.57 and 0.39-0.58%, respectively. Specifically, the total acid content of Ageude was 0.47% which was not high, when compared to those of other wines. However, the soluble solid content was 7.85 °Brix, which was higher than those of the other wines. In terms of color, the redness, color intensity, and hue values were all considerably high. Moreover, the total phenolic content and total anthocyanin content of Ageude were notably higher than those of the other cultivars. However, it is worth noting that proanthocyanidin was not detected. Based on these findings, Ageude is an excellent cultivar for producing red wine, owing to its high total anthocyanin content and redness due to the absence of proanthocyanidin, it is more suitable for producing short-term aging wine rather than long-term aging wine.
