In July, shoots continue to expand and vine flowers become berries. This is called berry set. (French word 'nouaison')
August is the month of veraison : berries grow, soften and change colour as they begin to ripen. During maturity, acidity levels decrease and sugar content increases.
The quality of a wine depends partly on the date of the harvest. We try to determine optimal maturity by tasting the grapes at each parcel and using chemical analysis; we consider optimal maturity as the convergence between aromatic maturity, phenolic maturity (colour, tannin) and technological maturity (sugar, acidity).
