Interlaken is an American, seedless, white/yellow, table grape.
Berries develop good sugar around 22 Brix.
Ripens very early, about six weeks earlier than Concord and is very productive - up to 30 pounds per vine. A good grape for cool climates or places with short seasons. Hardy to about -15F.
Interlaken has firm berries on well-filled to compact clusters. Also good for raisins and the berries make good frozen fruit.
The vine produces well when trained to cordons with two or three bud spurs.
