The Oger vineyard, classified as Grand Cru, sits on pure Campanian chalk soil. 100% Chardonnay.

The grapes are pressed slowly at low pressure to obtain exceptionally clear must. Alcoholic fermentation takes place naturally in temperature-controlled stainless steel tanks. Aging on fine lees for several months before bottling allows the wine to gain density while preserving the precision of the fruit. After racking, the wine rests for more than 5 years on its lees in the cellar before disgorgement and the minimum dosage.
