All grapes are handpicked during the early morning hours and then cooled overnight in a temperature - controlled room at 5 °C. Grapes are then crushed, destemmed and pressed. The free run and pressed fractions are kept separate. Dry ice (CO₂) is used during this process to prevent oxidation. The juice settles in stainless steel tanks for 48 hours at 8 °C. The clear juice is then racked from the thick lees and inoculated with VIN 7 and QA 23 yeast. Fermentation, which takes place at 12°C, takes average 30 days to complete. After fermentation, the wine is given a low dose of sulphur and left on the lees for four months before it is blended and bottled.
