Hi Most elderberries are edible and are used to make herbal tea,Jams and wine just as the Black elderberry is used. Some varieties are better than others and some produce bigger berries that are tastier. I think though it has been miss labled as I believe it is suppose to be a light yellow or golden in color and not red. I could be wrong on this, but I believe that there is a red variety that is call by another name.
