Blueberry wine is generally made from natural wild blueberries through multiple processes. After blueberry is fermented into wine, not only the nutrients are not lost, but also the anthocyanins, selenium, amino acids, vitamins, calcium, phosphorus, iron, zinc and other nutrients are richer, which are more easily absorbed by the human body, and the taste is more attractive than ordinary blueberry fruit and blueberry juice, so it is called "liquid gold" and "oral cosmetics".
