This property can help reduce the risk of food poisoning by inhibiting the growth of bacteria like E. coli and H. pylori.

4. Potential Cancer Prevention: The antioxidants found in fermented cranberry juice may have a protective effect against certain types of cancer, including breast, colon, and prostate cancer.

This helps to distribute the yeast evenly and promote fermentation. After the 5-day period, you can taste-test the fermented cranberry juice to check if it has reached the desired level of fermentation.
