The small green berries are formed after the flowers get fertilized.
Actually not every flower on the grape vines gets fertilized, the unfertilized flowers eventually fall from the vines.
The grapes need sunlight to ripen, so at this period the winegrowers trim the vine leaves to have a better sun exposure. However, too much sun can burn the grapes! One of the winegrowers explained that the grapes of the vine facing south get burned more easily as they get sunlight from morning until evening.
