Côte de Sézanne, Champagne
The Côte de Sézanne is Champagne's quiet southern continuation of the Côte des Blancs — geologically the same chalk, climatically a bit warmer, and reputation-wise still very much under the radar. It's essentially an extension of the same geological fault that the famous Côte des Blancs sits on, but it stretches further south and west, running roughly 30 kilometres from Allemant in the north down to Villenauxe-la-Grande, well away from the grand cru fame of its northern neighbor.
The history runs deep, even if the recognition hasn't always followed. Vines have been grown around Villenauxe-la-Grande, on the southern edge of the Sézannais, for more than a thousand years, and the town held a privileged position along the route of the famous Champagne trade fairs in the Middle Ages. There's also a charming, half-legendary claim attached to Chardonnay's arrival here: local lore holds that the first Chardonnay vine was planted at Sézanne under the reign of King Louis IX, the Saint — placing the grape's roots in this exact spot as far back as the 13th century.
What sets the Côte de Sézanne apart from its more famous neighbor is mostly down to exposure and a few degrees of warmth. The slopes here face predominantly south, getting more direct sun than the east-facing Côte des Blancs, and the climate runs slightly warmer overall. The chalk underneath is technically a different, slightly younger geological layer — Santonian-Campanian chalk rather than the Kimmeridgian limestone found further south in the Aube — and often comes mixed with clay, sand, or tuffeau, rather than the nearly pure chalk of the Côte des Blancs. The combined effect is Chardonnay with a different personality: riper, rounder, and more "tropical" in style, with stone fruit, citrus, and floral notes, and generally lower acidity than the more austere, mineral-driven Côte des Blancs reference style.
Despite its size, the Côte de Sézanne contains no Grand Cru or Premier Cru villages at all — every village here is classified as "autre cru," which has kept the region's profile modest even as Chardonnay now accounts for over 75% of plantings, increasingly steered toward exactly the Blanc de Blancs style that's made the Côte des Blancs so famous. For a long time, most of that Chardonnay simply disappeared anonymously into the non-vintage blends of major Champagne houses, valued for its softness and fruit without ever getting its own name on a label. That's slowly changing, with grower-producers like Collard-Picard now crafting terroir-driven wines that showcase the region's roundness and fruitiness on its own terms.
That's exactly the story BoundbyWine likes telling: a region with genuine geological and historical credentials, riding on the coattails of a far more famous neighbor for decades, only now starting to get bottled and sold under its own name rather than disappearing into someone else's blend.
In this collection you'll find Blanc de Blancs Champagne from the Côte de Sézanne — riper, rounder, and more immediately fruit-forward than its famous northern cousin, and often a noticeably better value for genuinely high-quality Chardonnay-driven Champagne
