Fully ripe currants are slightly soft, juicy, and develop the characteristic color of the variety.
Most currant varieties are red at maturity, a few are white.
For jellies and jams, pick the currants when they are still firm and not completely ripe. Harvest currants by picking the fruit clusters rather than the individual berries. After picking, the individual berries can be stripped from the stems. Currants can be stored in the refrigerator at 35 to 40oF for approximately two weeks. Fully ripe elderberries are plump, slightly soft, and dull purple in color.
