Beyond our passion for forgotten grape varieties and the exploration of our terroirs, Château Cazebonne is resolutely committed to a winemaking approach that respects nature and the integrity of our wines. It is in this spirit that we have developed our "no added sulphur" cuvées, an approach reflecting our desire to offer the purest expression of our grapes and terroir.

Sulphur, or sulphur dioxide (SO2), is traditionally used in winemaking for its antioxidant and antiseptic properties. However, it can sometimes mask the authentic aromas and flavours of the wine. At Cazebonne, thanks to vines cultivated under organic farming, immaculate hygiene in the cellar, and complete mastery of the vinification process, we succeed in crafting wines without any added sulphur. This approach demands constant vigilance, rigorous grape selection, and precise expertise.

The result? Wines bursting with fruit, offering tremendous freshness and remarkable drinkability. Our no added sulphur cuvées reveal intense, complex aromatic profiles where varietal typicity and the subtlety of our terroir express themselves with striking clarity. They open the door to new sensations—an invitation to rediscover the power and delicacy of unadorned wine.

Choosing a no added sulphur cuvée from Château Cazebonne means choosing a living wine, a vibrant echo of nature. It means prioritising pure taste, authentic flavours, and your well-being. These wines prove that tradition and innovation can be combined by returning to what matters most: the grape, the terroir, and the winemaker's craft.

Replanting lost grape varieties in Bordeaux and pursuing this no added sulphur winemaking approach are long-term endeavours, made possible by the unwavering support of the many wine enthusiasts who enjoy our wines. Your trust allows us to continue innovating and preserving this precious viticultural heritage.

You can find all our cuvées available for purchase in the Cazebonne online shop.

A Commitment to an Authentic Expression of Terroir

At Château Cazebonne, our no added sulphur cuvées embody our philosophy of respecting the grape and the terroir. They are the result of a holistic approach from vineyard to bottle, where every stage is designed to minimise intervention and let nature express itself. The absence of added sulphur allows the fruit to shine in all its glory, offering intense primary aromas and vibrant freshness. It is an invitation to (re)discover wine in its purest form, just as it came from the vine.

The Vintage and its Influence on Our No Added Sulphur Cuvées

Each vintage brings its own unique characteristics, and this is especially true for wines made without added sulphur. The year's weather conditions have a direct impact on the sanitary condition of the grapes, a crucial factor in this style of winemaking. A warm, dry vintage, for example, promotes optimal ripeness and excellent aromatic expression while making microbial populations easier to manage. Conversely, a wetter vintage demands heightened vigilance and an even stricter sorting of the berries to safeguard the integrity of the unsulphured wine.

The Cazebonne Terroir: An Asset for Sulphur-Free Winemaking

Our unique Asteria limestone (calcaire à astéries) terroirs play a leading role in the success of our no added sulphur cuvées. The mineral-rich composition of our soils gives the grapes natural aromatic complexity and a structure that fosters wine stability. Furthermore, healthy and balanced vines, rooted in living soils like those at Cazebonne, yield naturally more resilient fruit, greatly facilitating the creation of wines without added preservatives. It is this seamless synergy between soil, vine, and climate that enables such authentic expression.

Meticulous Vinification and Tailored Ageing

Crafting wines with no added sulphur requires exemplary technical precision. At Cazebonne, every step of the vinification process is designed to preserve the fruit. Grapes are hand-harvested at optimal ripeness and then sorted with meticulous care. This is followed by natural fermentation without oenological additives, followed by maturation where oxygen is precisely managed to prevent oxidation, often in inert vessels such as concrete or stainless steel vats. The aim is to guarantee aromatic purity and wine stability without resorting to sulphur. Our expertise in biodynamics (learn more about biodynamics) guides us through this exacting process.

Tasting Profile: When Fruit Takes Centre Stage

The no added sulphur cuvées from Château Cazebonne are distinguished by exceptional freshness and remarkable fruit intensity. On the nose, they reveal a vibrant aromatic bouquet, often dominated by crunchy red berry notes (raspberry, blackcurrant) for the reds, and citrus or white flowers for the whites. On the palate, these wines offer a silky texture, lovely roundness, and a long, refreshing finish without any harshness or astringency. It is a sensory experience where pure fruit reigns supreme, offering immediate approachability and unparalleled drinking pleasure.

Food & Wine Pairings: The Versatility of No Added Sulphur Cuvées

Thanks to their freshness and vibrant fruit expression, our no added sulphur cuvées offer wonderful culinary versatility. An unsulphured red wine will pair beautifully with simple, authentic cuisine such as a charcuterie board, Mediterranean vegetable pasta, pizza, or a summer barbecue. The whites, meanwhile, are an ideal match for seafood, grilled fish, or fresh cheeses. These wines are made for sharing and suit convivial gatherings effortlessly, delivering a flavour experience sure to please every palate.
