Purpose: Korea is also one of the markets that is growing significantly in the wine market. Due to this influence, Korean mainstream franchises are also increasing the proportion of wine sales. This study aims to examine the sustainability of wine brands from the perspectives of environment, organic farming, and ecological protection, and to verify the influence of these factors on consumer attitudes and intimacy. Research design, data, and methodology: The data were collected from 306 wine purchasers aged 20 or older and analyzed with SPSS 25.0 and SmartPLS 4.1. A total of 311 questionnaires were collected, and 306 were used for analysis after excluding 5 incomplete questionnaires. Result: The findings showed that the environment, organic, and ecological protection positively influence intimacy. In addition, organic positive influences attitude, but the environment and ecological protection did not influence. Intimacy positively influences attitude and loyalty, and attitude also positively influence loyalty. Conclusions: First, this study explained consumers' perception of the sustainability of wine brands through self-identity theory. Second, wine brands need to develop wineries into eco-friendly regions. Third, marketing should focus on the environment of the winery region.

This study investigated the antioxidant activities of wine made with aronia (Aronia melanocarpa). The ethanol concentration of the aronia wine was increased up to 7.8±0.1% on the 8th day of fermentation. Compared to other types of wine, the total amount of organic acids was highest in raspberry wine, followed by grape wine, arona wine, and aronia juice. Because, acetic, oxalic, and succinic acids were not detected in the aronia juice, but were detected in the aronia wine, it was determined that they were produced during alcohol fermentation. The polyphenol content in the aronia juice and wine was higher than in the grape wine and raspberry wine and was twice as much in the aroni wine than in the aronia juice. The flavonoid content in aronia juice and wine was higher than in commercial grape wine and raspberry wine. The DPPH radical scavenging ability was higher than 50% in the aronia wine and juice samples. ABTS radical scavenging activity was higher in aronia juice and wine than in raspberry wine and grape wine. The results of this study suggest that the development of wine with high antioxidant activity is possible if wine is made with aronia.

The purpose of this study was to investigate the quality characteristics and volatile flavor components of Doonuri wine, using freeze concentration. The freeze concentration can increase the sugar concentration in grape juice by reducing its water content. In this study, after eight days od fermentation, the alcohol content of freeze-concentrated Doonuri wines was 12.5~14.1%. The pH of the wine was 3.42~3.50 and the total acid content was 0.68~0.94 g/100 mL, respectively. The brghtness of freeze-concentrated Doonuri wines was 19.28~54.42, the redness was 41.98~49.58, and the yellowness was 36.16~42.36. The organic acid analysis of Doonuri wines was that most of the organic acids contain tartaric and malic acid. By using freeze concentration with grape juice, significant increase in the total polyphenol content of Doonuri wines was 122.40~137.26 mg/mL, the total anthocyanin content was 117.06~118.40 mg/L and the tannic acid content was 66.23~83.70 mg%. In GC/MS analysis, the volatile flavor component analysis of Doonuri wines identified six alcohols, five esters, two ketones, on acid, two alkanes, and four other compounds.

This study investigated the quality characteristics and volatile flavor components of aronia wine (Aronia melanocarpa (0~100%)). After 12 days of fermentation, the alcohol contents of aronia wines ranged between 9.0~12.0%. The pH level and total acidity of aronia wines were 3.20~3.68 and 0.57~0.76 g/100 mL, respectively. The organic acid analysis of wine containing 100% aronia, revealed malic acid content at 3.70 mg/mL, followed by tartaric acid, lactic acid, and citric acid. As the aronia content increased, both the total polyphenol content and the antioxidant activity (the DPPH radical scavenging activity) also significantly increased. The total polyphenol content was the highest in the wine with 100% aronia (461.33 mg%), and the antioxidant activity showed the highest values in the wine with 100% aronia (91.91%). Volatile flavor component analysis of aronia wines identified 8 alcohols, 12 esters, 4 ketones, and 7 other compounds. In the sensory evaluation, the color, flavor, and taste of wine with 20% aronia showed higher values than other aronia wines. Based on the results of the present study, we suggest that 20% aronia is most beneficial in improving the quality as well as sensory characteristics of the wine.

본 연구는 흑미를 첨가하여 막걸리를 제조하여 항산화 및 발효특성을 살펴보았다. 항산화 활성은 대조구에 비해 흑미 첨가구가 높았으며 특히 DPPH 라디칼 소거능은 안토시아닌 함량과 비례하였다. 발효 3일째, pH는 급격히 감소하였으며 대조구에 비해 흑미 첨가구가 낮았다. 환원당과 유리당은 1일째 급격히 증가하였다가 그 이후 감소하는 경향을 나타내었는데 이는 발효 초기에 당화 효소 활성으로 쌀의 전분이 glucose와 maltose 등으로 분해되기 때문이다. 모든 유기산은 발효 동안 증가하였으며 lactic acid가 가장 높은 증가율을 나타내었다. 발효 동안 흑미 첨가 막걸리의 lactic acid와 succinic acid는 대조구와 큰 차이를 보이지 않았다. 발효 초기 젖산균수가 증가하여 3일째 최대에 달하였으며 이는 lactic acid가 급증한 시기와 일치하였다. 또한 흑미 첨가량이 많을수록 젖산균수가 높았다. 색도는 흑미의 붉은색의 영향으로 대조구에 비해 흑미 첨가구의 a값이 높았다. 관능검사 결과 외관은 흑미 첨가구가 높은 점수를 받았으나 전체적으로 단맛과 신맛의 영향을 받아 대조구와 20% 첨가구를 선호하는 것으로 나타났다. 흑미를 첨가할수록 항산화 성분은 증가하나 관능평가 결과로 보았을 때 흑미는 20% 수준 첨가하는 것이 바람직한 것으로 나타났다.

To investigate the aroma and quality characteristics of wine bestowed by the degree of ripening of Cheongporang grapes, the general quality composition, color, organic acid, physiological activity, aroma component and sensory evaluation were analyzed. The general characteristics of the wine assessed were pH 3.34~3.50, total acidity 0.46~0.67%, color intensity 0.074~0.116, lightness 98.99~99.74, redness -0.39~0.01, and yellowness was 1.52~3.10. Malolactic fermentation was not relative to the contents of malic acid and lactic acid. The total polyphenol content and antioxidant activity were lowest in C3 wines made with ripe grapes and highest in C4 wines made with mixed grapes. Aroma analysis identified 6 alcohols, 15 esters and 5 miscellaneous compounds. Compounds with higher odor activity value (OAV) were 3-methyl-1-butanol, ethyl butanoate, isopentyl acetate, ethyl hexanoate, ethyl octanoate, ethyl decanoate and octanoic acid. The C4 wine, a mixture of grapes with different degrees of ripening, had the highest ester content and ratio. The lowest values were found in the C3 wine made with ripe grapes. Results of the sensory evaluation related the C4 wine, containing a large amount of ester compounds having high OAV values as the aroma component, as the best and most preferred wine.

The objective of this study was to investigate the quality characteristics of Cheongsoo wine using freeze concentration fermented with 5 kinds of yeast strains (Saccharomyces cerevisiae EJ18, EJ30, HK22, HK32 and Fermivin). We compared the characteristics, volatile flavor component and physiological activity of 5 wines. The freeze concentration can increase the sugar concentration in grape juice by reducing its water content and the alcohol content of freeze-cententrated Cheongsoo wines ranged between 15.0~15.8%. The pH of wines ranged from 2.92 to 2.94 and the total acidity and soluble solid of wines ranged from 12.40~13.27. °Brix. The major organic acid in the wines was tartaric acid (4.49~5.11 mg/mL) and malic acid (7.00~7.97 mg/mL). It contains higher functional compounds in wine fermented with yeast (EJ18, EJ30, HK22, HK32) than wine fermented with fermivin. α-glucosidase and tyrosinase inhibitory activity had the highest values (78.87% and 62.25%) in wine fermented with HK22 and EJ18 yeast, respectively. 16 volatile flavor compounds (alcohols, esters, ketones, acids, and others) were detected in the Cheongsoo wines by freeze concentration. These results provide useful information that the quality characteristics of wine developed by the freeze-concentration method using grapes cultivated in Korea.
