bunch, or cluster, the viticultural term for that part of the grapevine comprising bunchstem and berries. Grappe is the French term. Before the berries set, each berry position is occupied by a flower; a bunch develops from the inflorescence of the vine once the berries have set. In the grapevine the inflorescence grows at the node on the side of the stem opposite to a leaf, an unusual position within the plant kingdom. It is closely related to a tendril, both deriving from the same embryonic organ, the anlage. Depending on the time of development, anlagen produce bunches, tendrils, or second crop.
