Tenah bears medium to large black currants in long clusters, with a sweet and tart flavour and fruit that is easy to pick. It is a productive midseason variety with moderate vigour and slightly spreading growth. Grower observations describe comparatively sweet fruit, though it retains the acidity of a black currant.

This Dutch cultivar was registered in 1973. Observations from the Polli germplasm collection in Estonia describe fairly good resistance to powdery mildew, leaf fall disease and currant gall mite. These are reported responses, not immunity or results from a Manitoba trial.
