Description, from Wikipedia

The nearly black berry, which is smaller than a gooseberry and a bit larger than a blackcurrant, is edible both raw and cooked. It is described as having a taste intermediate between a gooseberry and a blackcurrant, with the gooseberry flavor more dominant in the unripe fruit, and the blackcurrant notes developing as the fruit ripens. The ripe fruit will hang on the bush in good condition through late summer, but is very popular with birds. The somewhat unripe fruit can be used in cooking recipes as a gooseberry. Like blackcurrants the fruit freezes well, and like many other members of the genus Ribes it is rich in vitamin C.

Commercial production of jostaberries is limited because they are not well suited to mechanical harvesting. Compared to most other fruits, harvesting jostaberries is relatively labor-intensive per kilogram. Although harder to pluck than blackcurrants, the plant is thornless.

The plant itself grows to a maximum height of about 2 m, flowering in mid-spring, with fruit setting and ripening on a similar timetable to the blackcurrant. The plant displays hybrid vigor, growing and fruiting well and being resistant to a number of common diseases afflicting other Ribes. In particular the plant is resistant to American gooseberry mildew, blackcurrant leaf spot, white pine blister rust, and big bud gall mite. Flowers are hermaphrodite and the plant is self-fertile following insect pollination. Propagation is usually by cuttings, rather than by seeds.
