At Château Cazebonne, we explore sparkling wine in its most authentic form with our Pét-Nat cuvées. Short for “pétillant naturel”, this term refers to an ancestral winemaking method (méthode ancestrale) where alcoholic fermentation finishes directly in the bottle. This process traps the carbon dioxide, giving rise to lively, fruit-forward wines of brilliant freshness, with a delicate, natural mousse. This approach is part of our commitment to diversifying Bordeaux's offerings with wines that express their terroir's character as purely as possible.

Gaz'bonne: spontaneous in-bottle effervescence

Our Gaz'bonne cuvée is a signature expression of this philosophy. It is an unapologetically natural sparkling wine, crafted from a blend of Sémillon and Sauvignon, two hallmark grape varieties of our region. Unlike the traditional method, Gaz'bonne is not disgorged, which lends it remarkable authenticity and may leave a light sediment—a true testament to its natural character and aromatic richness. It is a natural wine in Bordeaux that promises an indulgent, surprising tasting experience.

The 2022 vintage of Gaz'bonne

The 2022 vintage of our Gaz'bonne Petnat is particularly representative of our philosophy. Made with 80% Sémillon and 20% Sauvignon, it offers a rich aromatic profile and a palate that is both textured and crisp. Bottling took place in December 2022, allowing the prise de mousse to unfold naturally over the winter. This vintage stands out for its fine bubbles and expressive character, the result of spontaneous fermentation on fine lees. A living wine par excellence, it reflects our expertise and our deep respect for the fruit.

Origin: a Graves terroir for unique Petnats

Our Petnats draw their unique character from Cazebonne's clay-gravel terroir in the Graves appellation. These well-drained soils, with their excellent heat-retaining properties, are ideal for promoting grape ripeness while preserving vibrant aromatic freshness. Sémillon and Sauvignon thrive here, delivering a seamless balance between richness and vivacity. The expression of this terroir is magnified by the ancestral method, faithfully translating the nuances of the soil and climate into the glass.

Vinification and ageing: the art of pétillant naturel

Winemaking for our Petnats at Cazebonne is entirely focused on preserving the grape's natural expression. Following hand-harvesting, the grapes are gently pressed. Alcoholic fermentation, initiated by indigenous yeasts, is halted before completion by bottling. It is in the seclusion of the bottle that fermentation resumes and finishes, creating the signature bubbles of Pét-Nat. Leaving our Gaz'bonne undisgorged preserves all the fine lees, enriching the wine with aromatic complexity and texture. This deliberate choice ensures an authentic wine full of vitality.

Tasting profile: freshness and fruit

The Petnats of Château Cazebonne, such as our Gaz'bonne, captivate with a tasting profile that blends freshness and fruitiness. You will discover vibrant notes of citrus, white-fleshed orchard fruits, and a delicate floral touch. The mousse is fine and persistent, delivering a crisp sensation on the palate. The texture, often lightly creamy thanks to the lees, brings a lovely roundness that balances the natural acidity. It is a wonderfully refreshing, thirst-quenching wine with a clean, invigorating finish—perfect for convivial occasions.

Suggested food and wine pairings

The vibrancy of our Petnats makes them ideal companions for a wide array of dishes. Gaz'bonne pairs delightfully with seafood tapas, oysters, or cheese gougères, adding a touch of freshness and lightness. Its liveliness also makes it a fantastic partner for aperitifs and standing buffets. For dessert, venture with a lemon tart, whose sharp acidity will be beautifully balanced by the fruitiness of the Petnat.
