Aronia Berry - A pea-sized, violet-black berry with a strong, dry and sour flavor that grows on deciduous shrubs native to eastern North America. Interest in the health benefits of aronia juice is based on its very high levels of anthocyanins and flavonoids, which are five to 10 times greater than cranberry juice, and has beneficial nutrients such as antioxidants, polyphenols, minerals and vitamins. It also includes compounds that may specifically fight cancer and cardiac disease.
