Jostaberry
The Jostaberry is a hybrid berry that blends the flavors and traits of black currant and gooseberry, prized for its vigorous growth, disease resistance, and versatile culinary uses.
Origin Story
Developed in Germany during the 1970s by Dr. Paul Lorenz at the Institute for Fruit Breeding, the Jostaberry was created by crossing black currant (Ribes nigrum), European gooseberry (Ribes uva-crispa), and North American gooseberry (Ribes divaricatum). Its name is a fusion of the German words for currant (Johannisbeere) and gooseberry (Stachelbeere), reflecting its unique pedigree and continental roots.
Classification
Jostaberry is classified as an interspecific hybrid within the Ribes genus, family Grossulariaceae. While not a true botanical berry, it is grouped with soft fruits in culinary and agricultural contexts. Its lineage combines species typically regarded as currants and gooseberries, placing it at the intersection of these two well-known berry groups.
Appearance or Form
Jostaberry plants are robust, thornless shrubs reaching 1.5–2 meters in height. Their leaves resemble those of currants, while the berries themselves are nearly black to deep purple, measuring 10–15 mm in diameter. The fruit grows in small clusters and offers a tart-sweet flavor, visually and sensorially bridging the gap between its parent species.
Behavior or Usage
Jostaberries are enjoyed both fresh and processed, with their tartness lending itself to jams, jellies, juices, pies, and wine. The plant’s high yield and disease resistance make it popular among home gardeners and specialty growers. Its self-fertility and adaptability to various soils further enhance its utility in diverse environments.

- It is highly resistant to common Ribes diseases such as American gooseberry mildew and black currant leaf spot.
- Jostaberry bushes can yield up to 5–6 kg of fruit per season under optimal conditions.
- Its berries contain high levels of pectin, ideal for making preserves.
- The plant is self-fertile, requiring no companion pollinator for fruit set.
Botanical Traits
Jostaberry is a thornless, vigorous shrub reaching up to 2 meters in height. Its leaves resemble currant foliage, and the berries are intermediate in size (10–15 mm), nearly black to deep purple, and borne in small clusters. The plant is self-fertile, ripens in mid- to late summer, and combines the morphological traits of both currant and gooseberry species.
