Ribes × nidigrolaria · Grossulariaceae · also known as Josta, Jochelbeere
A thornless German-bred cross of blackcurrant and gooseberry — glossy black berries with the currant's deep musk and the gooseberry's bright tang. A modern hybrid built for the home garden, spilling into jams, cordials, and summer puddings.

How to select & store
Picking a ripe one
Choose plump berries that have turned fully black with a slight give — reddish-purple fruit is tart and underripe. Ripe jostaberries hang like large blackcurrants and release easily from the bush.
Storing it
A few days refrigerated fresh; they freeze excellently, keeping their color and flavor for months. The glut is best turned into jam and cordial, exactly as with their currant parent.
Practical uses
🍽️ Culinary
- Jams, jellies, and cordials with a blackcurrant-gooseberry richness
- Baked into pies, crumbles, and summer puddings
- Eaten fresh, fully ripe, straight from the (thornless) bush
- Fruit wines, sauces for game, and yogurt swirls
🌿 Health & traditional
- Shares its parents' antioxidant reputation; valued mainly as a nutritious garden berry
🎎 Cultural
- A deliberate breeding success — its name fuses the German Johannisbeere (currant) and Stachelbeere (gooseberry)
- Prized by home gardeners for being thornless, vigorous, and disease-resistant where gooseberries struggle
Eating jostaberry: what to know
What regular consumption looks like
Jostaberry is a nutritious everyday fruit, best enjoyed as part of a varied diet. It is a good source of fibre (about 3 g per 100 g), which supports digestion and satiety. It is exceptionally rich in vitamin C — even a small portion far exceeds a day's needs — supporting immune function, collagen formation, and the absorption of iron from plant foods. Its pigments and polyphenols are antioxidants that population studies associate with heart health, though that reflects overall diet rather than any single fruit.
Sensible amounts
A typical fruit serving is roughly a handful, one medium fruit, or about 80 g, and two or more varied fruit servings a day is a sensible everyday pattern.
Evidence & conditions
As a whole fruit, Jostaberry contributes fibre, vitamins, and beneficial plant compounds, but it has not been shown to treat or prevent any specific condition — so it is best enjoyed as part of a healthy diet rather than as a remedy.

The jostaberry is a fruit with a birth certificate and a portmanteau name. Bred in Germany through the 20th century and released in the 1970s, it crosses the blackcurrant with two gooseberry species — and its name, Josta, welds together the German Johannisbeere (currant) and Stachelbeere (gooseberry). The goal was a berry with the best of both parents and the thorns of neither.
The best of two currants
It largely succeeded. Fully ripe, a jostaberry hangs like an oversized blackcurrant — glossy black, grape-sized — and tastes like one too, with the currant’s deep musk and vitamin-C tang, rounded out by the gooseberry’s brighter acidity and snap. Picked a little early, when the fruit is reddish-purple, it leans sharp and gooseberry-like; left to blacken, it mellows toward sweet. Either way it does what both parents do best: makes exceptional jam, cordial, and summer pudding.
A gardener’s fruit
Jostaberries are grown less by farmers than by home gardeners, and for good reason: the bush is thornless (unlike its prickly gooseberry parent), vigorous, and resistant to the mildew and white pine blister rust that plague currants and gooseberries. It shrugs off cold, crops heavily, and needs little fuss — a low-maintenance berry engineered for exactly the person who wants fruit without a fight.
Using the harvest
Treat jostaberries as you would their parents, only bolder. They freeze beautifully, jam and jelly with the currant’s natural pectin and color, ferment into fruit wine, and make a fine sharp sauce for game. Fresh off the bush, fully black, they’re a rich handful. Set them alongside redcurrant and blackcurrant for a full northern-berry preserving day.
