A Historic Alpine Estate

Tucked into the French Alps along the Rhône and Ain rivers, Lambert de Seyssel is one of the oldest and most storied producers in the Seyssel appellation — a region recognized as early as 1942 as an official AOC for sparkling wine. Seyssel itself has a winemaking tradition stretching back centuries, and Lambert de Seyssel has played a central role in preserving and advancing this heritage. Known as the benchmark producer of the region, their wines remain a touchstone for what Savoie’s alpine terroir can express when crafted with care and patience.

Seyssel: The Birthplace of Alpine Sparkling

The Seyssel region lies on the western edge of Savoie, where steep slopes and glacial soils create a unique environment for white grapes. Cooler alpine temperatures preserve acidity and freshness, while the mix of limestone, clay, and glacial moraine soils lends minerality and structure. This terroir has historically been celebrated for sparkling wines that combine aromatic finesse, precision, and longevity — wines distinct from Champagne yet equally noble.

Indigenous Grapes, Alpine Identity

At the heart of Lambert de Seyssel’s wines are two native white grapes: Molette and Altesse (also known as Roussette).

• 
  Molette provides freshness, delicacy, and floral aromatics.
  
• 
  Altesse brings body, structure, and a characteristic honeyed and nutty complexity as it ages.
  

Together, they form the backbone of Seyssel’s sparkling tradition. By focusing on these historic varieties, Lambert de Seyssel preserves a viticultural identity unique to Savoie, ensuring that each wine speaks not only of its terroir but also of centuries of local tradition.

Méthode Traditionnelle with Patience

Lambert de Seyssel employs the méthode traditionnelle — the same secondary fermentation in bottle used in Champagne — to create wines of finesse and depth. But their hallmark is extended lees aging:

• 
  The base wine is aged ~10 months on the lees before secondary fermentation.
  
• 
  After bottling, the wines rest a minimum of two years sur latte (on their sides) before release.
  

This patient approach yields wines with delicate mousse, rich texture, and layered aromatics. Notes of alpine flowers, orchard fruit, wild honey, brioche, and mineral tension are signatures of the house style.
