It is essential to harvest the cones before it rains and, if possible, do not wash them so that the pollen remains (gives color and taste).
Put the cones in a container with the water and citric acid. This mixture stands in the refrigerator or very cold for 24 hours. Then take out the cones. If a few flowers remain, it doesn`t matter. Then stir the sugar into the cold elderberry water until it dissolves. Fill up the liquid with the grain. Fill in bottles, give away or drink yourself.
