Description
Summary:In this paper, the influence of bottle storage time on different blueberry wines has been studied. Four blueberry wines with different fruit weight/sugar solution volume ratios and different fermentation times were stored. The storage was conducted for 12 months in darkness and at a constant temperature of 4°C. All the wines showed a similar behavior during the 12-month study period. The concentration of anthocyanins decreased significantly after the storage period. Wines obtained through partial fermentation showed a low concentration of anthocyanin monomers, and in the case of wines from total fermentation, no anthocyanin monomers could be identified. However, the wines at 12 months of storage exhibited a significant contribution to red color. The color intensity experienced a sharp decrease from 0 to 4 months, remaining unchanged until 12 months. Moreover, antioxidant activity increased during the storage process from 0 to 4 months and then remained relatively stable up to 12 months.
