Veraison, pronounced “ver-AY-zhun”, is a French term that is used to describe the the onset of ripening, signaled by a change in color of the grapes. Veraison represents the transition from fruit growth to fruit ripening. Many changes in berry development happen during veraison, some very visible, as you can see in this time lapse video. Others are happening inside the grape berries, such as increased sugar levels.
Our team photographed a pinot noir cluster every 2 minutes for 3 weeks and compiled this veraison timelapse to see what happens as the grapes ripen in the vineyard.
