Section in the annual growth cycle of the grapevine after blossom (see also under BBCH Code ). The fertilized female ovaries of the flowers develop into berries. This occurs in the northern hemisphere in the months of June to July, in the southern from December to January. The amount of berries is among others of the vine dependent.

One berry contains up to five (rarely six) grape seeds, which are used as seeds for the breeding new varieties can be used by sowing and selection.
