Veraison refers to the time when grapes begin ripening.
If you grow grapes, you know that they start out as clusters of tiny spheres that don’t look anything like a grape. As they grow, they become more grape-like in appearance, but you wouldn’t want to eat one. An unripe grape is tough and very sour.
Grapes first grow to full size and then veraison begins. This is when acidity drops and sugar levels rise. This is also when grapes start to change color. Scientists do not know what triggers veraison, but now you know a garden word that most other people do not!
