The grapes are harvested by successive selection as soon as they optain optimal maturity. They are firstly selected from the vine where a group of 180 grape pickers is directed by the château staff. Then, eight people carry out a second rigorous selection around a 7-metre-long sorting table.

In order to eliminate the morning dew or rain, the grape then passes through a long isothermal passage equipped with a hot-air ventilation system. This machine (originally designed for drying delicate fruit such as white peaches), the only one of its kind in the Médoc, bears witness once again of a real commitment to perfection.
