All wines, even those made without added sulphites, contain ‘sulphur’ (sulphur dioxide in scientific language). During alcoholic fermentation, yeast always generates SO2 (sulphur dioxide, a chemical compound in the sulphite family), although the quantity produced is very small. So the presence of sulphites in wine is a natural process. Nevertheless, it is common practice to add additional sulphites to protect against possible spoilage of the product, to control fermentation and to ensure the stability of the wine.

Buzet winegrowers, our innovative group working for healthier wines, decided to produce wines without added sulphites in the land of Louis Pasteur! (Because it was he, the first oenologist, who imposed the use of sulphites to ensure the stability of wines!) It was a crazy gamble that paid off in 2011 with the launch of the first SANS cuvée. Since then, the cooperative has extended this practice of reducing sulphites to its entire range.

The production

Producing a sulphite-free wine is the result of meticulous work. It is essential to take great care from the moment the grapes are harvested. The grapes must be healthy: beware of damaged grapes that can carry bacteria and fungi. Hygiene in the cellar must be impeccable, and our teams must be vigilant at every stage of the winemaking process.

The early blending of the three grape varieties, although traditional, requires particular rigour in terms of hygiene and prevention of oxidation, with constant monitoring of production. The absence of added sulphites enhances the fruit aromas, keeps the wine fresh and preserves its deep colour. winegrowers from Buzet’s sulphite-free wines can be kept for 2 to 3 years thanks to a specific choice of technical closure, using a cork made from sugarcane fibre to minimise oxygen permeability and prevent oxidation.

The terroir

The parcels selected to make Cuvée SANS are located on the clay-limestone slopes of the Buzet appellation, chosen for their natural ability to produce wines that are both fruity and full-bodied. The sulphite-free vinification process enhances these organoleptic characteristics. For the 2021 vintage, the blend is composed of 60% Merlot, 30% Cabernet Franc and 10% Cabernet Sauvignon, selecting the latest Merlots for their aromatic concentration and intense colour, while the early Cabernet Francs bring elegance and structure thanks to their tannic qualities.
