Depending on the year, the harvest takes place between the end of September and mid-October, based on the ripeness of the grapes.
The Merlot grapes are always harvested first, as they ripen earlier. The grapes must be harvested at optimal ripeness, which means that the harvest date is important. Preserving freshness and fruitiness is decisive for the quality of the wines. The Cabernet-Sauvignon, which ripens a little later, is harvested afterwards. The grapes are less fragile, but the quality of maturity is a guarantee of quality for the wine. The Petit-Verdot is generally harvested last, as it ripens later than the other varieties. Its percentage is low in the overall blend, but this variety has tannic and aromatic strength which is important in the final blend of the wine.
