There are many varieties of elderberries. Similar to wine grapes, the variety in combination with the growing location attributes (such as the soil and elevation) can lead to berries of vastly different color, taste and minerals. We choose to use only the premium Haschberg variety of European black elderberries (Sambucus Nigra) to make every Sambucol product. Grown in the nutrient-rich soil of Central Europe, these elderberries are the highest in flavonoid compounds called anthocyanins which give the berries their dark color. In fact, their anthocyanin level is nearly double the amount in any other fruit! These compounds provide an extremely high level of antioxidants which can help support our immune systems when consumed.
