Blueberry wine is typically made from blueberries through multiple processes such as crushing, pressing, filtering, and low-temperature fermentation. After fermentation, the wine not only retains all the nutrients but also enhances the richness of anthocyanins, selenium, amino acids, vitamins, calcium, phosphorus, iron, zinc, and various other nutrients, making them more easily absorbed by the body. Its flavor is more appealing than that of fresh blueberries or blueberry juice, earning it the titles "liquid gold" and "oral cosmetic.".
