 The Munson grape itself is an inter-species hybrid created from two American grapevine species "Vitis lincecumii" and "Vitis rupestris".Couderc noir was discovered in 1886 in the garden of a pastry chef named Contassot from Aubenas in the Ardèche department.Contassot had plantings of Munson and when he observed the characteristics of this new vine, he gave the seeds to grape breeders Georges Couderc and Albert Seibel who began working with the variety.
