Sort the elderberries, wash and drain. Then crush and pour into a wide-mouthed jar with the alcohol. Place in a sunny place for about 7 weeks until the color is drawn out.
After this period, filter the juice. Boil the sugar with water and let it boil down over a longer period of time until a syrup is formed. Mix well with the filtered elder juice.
Bottle the liqueur and leave it in a dark place for some time.
