Veraison is the first sign of the grapes ripening. During this stage both the color and appearance of the grapes change. For red grape varietals, this is arguably the most beautiful and unique stage of their lifecycle on the vine. Take a deeper look into this stage of the process from vine to wine.
Veraison in grapes indicates the beginning of maturation, meaning harvest is coming soon! Not only does this stage get us closer to wine, but it actually shifts the entire focus of the grapevine.
The grapevine will now focus on ripening the grapes rather than growing new leaves. You may also notice grape clusters with both purple and green grapes. This is a sure sign veraison is happening!


During veraison, the chlorophyll in the grape skins break down. This allows the other pigments to become visible. The grapes will also start to become softer, ripening and getting ready to be harvested. While this stage is unique and fun to look at, there is a lot more going on than meets the eye.
Sugar levels increase, acidity decreases, then flavors and aromas start to fully develop. All of which are key to getting the grape ready to harvest and make into the wine we all enjoy!
