Veraison, a Masterpiece of Nature

The vine's annual cycle begins with flowering, when the small berries that will form the future bunches develop. The timing and success of flowering influence both the quantity and quality of the prospective crop.

Veraison marks the visible beginning of ripening. White grapes change from bright green toward yellow, while dark-skinned varieties develop shades of red. The rate and expression of this transition depend on the grape variety, temperature, solar exposure, rainfall and soil composition.

Inside the berry, chlorophyll breaks down as pigments including anthocyanins and flavonoids develop. Sugars and aromatic compounds accumulate while the acid balance changes, progressively establishing varietal and site-related character.

Periodic berry analysis is used to follow this evolution and choose the appropriate harvest date. Earlier picking can preserve greater freshness and acidity; later harvesting can produce fuller, more alcoholic wines. Veraison therefore serves as a practical signal that harvest is approaching as well as one of the vineyard year's most visible transformations.
