It is still a stubbornly held legend that the fruits of the rowanberry or mountain ash are poisonous. The small fruits are ideal for jam, mash, liqueur (an important ingredient, for example, in the “Sechsämtertropfen”), rowan schnapps (“Jeřabinka”) and rowan wine. In cider, rowanberries can be used as a substitute for sorbs, with which it is closely related.
So that the fruit does not taste too bitter, they should be harvested after the first frost. The parasorbic acid is converted into sorbic acid and the fruits begin to taste sweet. In addition there are cultivars which are poor in bitter substances, which are particularly sweet or suitable for juicing without further processing.
