The Chardonnay and Pinot Noir grapes are carefully hand picked to minimise maceration of grape bunches during transport. The crates are placed in refrigerated rooms at 4C to minimise the amount of colour extracted from the red skinned Pinot Noir grapes during pressing. The whole bunches are then loaded directly into the bag press and gently squeezed to produce a clear, fine juice fraction. The juice is then clarified and inoculated with native Champagne yeasts to ferment at cool temperatures. The percentage of Pinot Noir in the blend has gradually been increased to 80% to give greater depth of flavour and increased aromatics. The assemblage spends twenty seven months on tirage before disgorgement and liqueuring.
