Winery Harlin Père et Fils

Family-run for several generations, the estate is described as a long-established wine-growing business in the commune of Mareuil-le-Port. The official website and the institutional Champagne portal attest to the estate's historical presence and note renovations to its production facilities in recent years.

The estate declares a strong commitment to soil- and biodiversity-friendly viticulture: it practices cultivation oriented towards organic and sustainable farming, uses plant-based preparations, employs techniques such as ecological grazing, and keeps vineyard parcels separate in the cellar to preserve the identity of each site. Recognized environmental certifications in the Champagne region are also reported.

Vineyards situated in the Vallée de la Marne, with parcels in Mareuil-le-Port and additional vineyards in the Épernay and Tours-sur-Marne areas; the zone lies within the Marne department of the Champagne region.
