The Flavor Secrets Hidden in Veraison | Origins

The transformation of grapes during veraison shapes the timeless flavors of Cognac

In France’s Cognac appellation, the vineyards are a land favored by nature—where nature’s magic unfolds quietly.

The region’s chalky soils create a unique environment for grape growing. The porous soil allows roots to grow deep, drawing in the mineral essence of the earth. At this very moment, the grape clusters are entering veraison—the turning point from tart youth to ripe maturity—marking the beginning of the journey that gives birth to exceptional Cognac.

Veraison typically occurs 50 to 80 days after the grapevines bloom. During this time, the grapes undergo a profound transformation, from appearance to internal composition. For Ugni Blanc grapes undergoing veraison, they are the very beginning of producing fine Cognac. Nurtured by sunlight, soil, and gentle breezes, the once green and firm grapes begin to "change their faces" in just a few short weeks. Their green hue fades, giving way to a translucent golden yellow. Inside, sugar levels rise rapidly, acidity decreases, and the taste becomes smoother and more rounded. At the same time, the grapes start synthesizing a variety of aromatic compounds, laying the romantic foundation for the rich floral notes, lush fruit aromas, and the deep character imparted by aging in oak barrels that will one day unfold in the amber liquid of Cognac.

At this moment, the grapes in the vineyards are still gathering energy. Every drop of Cognac holds the full story of the grapes’ journey—from the vines to the glasses. From veraison to aging in oak barrels, it will all culminate in a lingering finish on the palate.

As we await the ripening of grapes, we also look forward to sharing with you the seasonal beauty and romance woven into the vineyards behind every bottle of Cognac.
