Viticulture & Sustainability
Antoine Grethen's vineyards are worked without chemicals. The elimination of herbicides, fungicides and insecticides is part of a consistent approach that continues in the cellar: no fining, no filtration and minimal sulfur use of 30 mg/l at bottling.
Vinification
Fermentation is spontaneous, without cultured yeasts. The base wines then age 24 months in barrel, followed by another 24 months lees aging after bottle fermentation. The dosage is 1 g/l (Extra Brut). Neither fining nor filtration is used — the champagne is bottled as naturally as possible.
The Cuvées in Detail

50% Pinot Noir, 50% Meunier · 1 g/l · 24 months barrel + 24 months lees · Base 2017/18/19 · Disgorged November 2024
