The grapes were hand harvested in the cool morning hours and brought to the winery as cold as possible. They immediately went into the press in whole clusters and were pressed to a chilled stainless-steel tank. The juice was inoculated using Prise de Mousse yeast, which is a traditional Champagne yeast and left to ferment for 20 days at 57 degrees. After fermentation and settling, the wine was bottled with a small amount of yeast and sugar to induce secondary fermentation. This process took about 12 months. After this, the bottles were riddled to bring the lees and sediment to the neck of the bottle. The necks were then frozen, and the lees were disgorged from the bottles. The bottles were then topped up and the final corks and wire hoods were put into place.
