SPARKLING WINES: THE ANCESTRAL METHOD VS THE TRADITIONAL METHOD
Traditional method :
The traditional method of making sparkling wine is the so-called "Champenoise " or "Champagne" method. It consists of making a still wine (base wine) first, and then transforming this wine into sparkling wine in the bottle. Sugars and yeast are added to the base wine in the bottle to generate a second fermentation called prise de mousse. It is during this second fermentation that the yeast converts the sugar into alcohol and carbon dioxide. It is not only the bubbles that are created at this stage, but also the development of a wide range of aromas. This is followed by a period called "remuage" which consists of rotating the bottles over a mandatory period of at least 9 months, in order to bring the lees deposit into the neck of the bottle. The desired level of sweetness (brut, demi-sec, doux) is achieved after disgorgement, with the addition of the liqueur d'expédition (a mixture of wine and sugar).
Méthode ancestrale
The so-called "ancestral" method, also known as the "Gaillacoise" method, is the original method of making sparkling wines in Gaillac. Not only is it technically different from the traditional method, now used almost everywhere in the world for the elaboration of sparkling wines, it also provides aromas that are different.
The wine is bottled early, before the end of the alcoholic fermentation of the must. This fermentation is completed inside the bottle and the wine foams naturally, without the need to add liqueur de tirage (a mixture of wine, sugar and yeast). Seasonal temperature differences play a role in this technique. In the spring, with the return of the heat, fermentation takes place again naturally.
This method is very old, much older than the méthode champenoise. Today, it is still used in Gaillac to make sparkling wines. There are three types of wine depending on the residual sugar content (between 10 and 80 grams). This sugar level indicates the type of wine: brut, demi-sec or doux. Sparkling wines made using the ancestral method are made from 100% Mauzac grapes. This technique allows the full expression of this grape variety as well as the optimal conservation of its aromas.
PRIMEURS WINES
Primeur wines are known for their crisp fruitiness and their typical aromas of sweets and sometimes banana. Although Primeur wines are often associated with Beaujolais Nouveau, other appellations also have their own range of Primeur wines, such as the Gaillac appellation. Made from the Gamay grape variety only, the carbonic maceration is done in a hermetically sealed vat with the whole bunches of grapes, not destemmed or crushed. The vat is quickly saturated with carbon dioxide, followed by an intracellular fermentation lasting 4 to 5 days. It is this fermentation technique that gives the Primeur wine its special aromas. These are amylic aromas, which are accompanied by a beautiful freshness and very reduced tannins, even barely perceptible.
Les Primeurs blancs, tout comme les rouges, sont aussi très rapidement mis en bouteille, puis en vente. La date est fixée : leur mise en vente est celle du 3eme jeudi du mois de novembre. Peu importe sa couleur, « Primeur » est une mention obligatoire sur l’étiquette.
