Champagne Antoine Grethen

Antoine Grethen

Antoine Grethen is a Récoltant-Manipulant with a consistently purist approach: spontaneous fermentation, 24 months barrel aging, 24 months lees aging, no fining, no filtration and minimal sulfur use at 30 mg/l. The vineyards are managed without chemical treatments.

Viticulture & Sustainability

Antoine Grethen's vineyards are worked without chemical treatments. The avoidance 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 occurs spontaneously, without cultured yeasts. The base wines then age for 24 months in barrel, followed by another 24 months on lees after bottle fermentation. The dosage is 1 g/l (Extra Brut). Neither fining nor filtration are used, the champagne is bottled as naturally as possible.

The Cuvées in Detail

Éole: Extra Brut

A lightly copper-colored champagne that combines Pinot Noir and Meunier in equal parts. The base comes from 2017, 2018 and 2019, totaling 48 months from barrel to bottling. On the palate it's lean and focused, with clear chalky texture, fine herbal spice and tart red fruit.

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