Domaine Marguet in the commune of Ambonnay was founded by Emile Marguet in 1875. The 10 hectare property is currently run by Benoît Marguet, who trained as a wine grower in the USA and with Mumm. The vineyard has been certified biodynamic since 2009. Benoît Marguet treats his vines with phytotherapy (the infusion and decoction of medicinal plants) and aromatherapy (use of essential oils); he also ploughs his land with horses and allows the grass to grow around the vines. In the winery, the single parcel vinification process is clean and precise and uses virtually no sulphur. The élevage is very well executed. The outcome is some very fine champagnes that are full of character and go well with food. This domain is attracting more and more champagne lovers.

The cuvée Les Crayères is a powerful and rich champagne, aged in oak barrels. It comes from a blend of Pinot Noir which gives it power and structure and Chardonnay offering great aromatic finesse.
