The Côteaux du Petit Morin is a lesser-known yet increasingly celebrated subregion within France’s Champagne appellation. Situated between the Côte des Blancs and the Sézannais, this area encompasses approximately 900 hectares of vineyards spread across 18 villages, including Congy, Coizard-Joches, and Beaunay. The region is characterized by its diverse terroir, featuring a mix of chalk, clay, and flint soils, which contribute to the unique profiles of its Champagnes.

Historically, the Côteaux du Petit Morin has been dominated by Pinot Meunier, accounting for about 46.9% of plantings, followed by Chardonnay at 40.5%, and Pinot Noir at 12.6% . However, recent trends show a growing emphasis on Chardonnay, particularly in villages like Broussy-le-Grand and Courjeonnet, where it comprises over 50% of the vineyards. This shift reflects a broader movement towards highlighting the region’s potential for producing high-quality, terroir-driven Champagnes.

Olivier Collin is the visionary behind Champagne Ulysse Collin, a domaine that has redefined the potential of single-parcel grower Champagne. Since reclaiming his family’s vineyards in the early 2000s, Collin has pursued a meticulous, terroir-driven approach, vinifying each plot separately and aging extensively on lees. With a background in law and a formative internship at Selosse, he combines analytical precision with bold experimentation. His Champagnes—marked by low dosage, barrel fermentation, and intense minerality—are now regarded among the most original and sought-after expressions of the Champagne.
