about the harvest: Grapes are harvested early morning and chilled to 7°C. Bunches are hand sorted, destemmed and crushed.

in the cellar : Selected parcels undergo a period of skin contact in tank to enhance flavour extraction, the remainder goes straight to press. After pressing the juice is settled for two days, racked, then yeast is added. Fermentation in tank occurs at 12-16°C until dry. The wine is left on the gross lees for 10 weeks. The 3% blended Sémillon undergoes a wild fermentation in barrel matured for 9 months in 2nd and 3rd fill French oak.
