Estello : Sparking Wine
The traditional method involves making a first fermentation of the wine in the vat followed by a second, slow fermentation in the bottle after the addition of a fermentation mix.
These are the different stages of preparation.
- Extraction
The blends are put together and bottled. A fermentation mix is added to guarantee the amount of sugar required to produce the fizz. A temporary cork is inserted.
- Cultivation
The bottles are placed horizontally in the cellar at a constant temperature of 10-12°C in order to start the second fermentation.
- Making the fizz
The second fermentation must happen very slowly to guarantee a constant stream of fine bubbles.
- Inverting the bottles
After a minimum 9 months in the cellars, the bottles are placed in racks, top down, in preparation for activating the contents.
- Activation
Using a quick, circular motion and a measured movement, each bottle is turned little by little whilst remaining top down, resulting in the sediment collecting in the neck ready for extraction.
- Inspection
The position of the sediment and the clarity of the wine are examined by inspecting each bottle by backlight.
- Decanting
The sediment is expelled from the neck of the bottle using a quick and precise jerking movement, which prevents the fizz and the wine from escaping. The modern way is to freeze the neck of the bottle before opening it.
- Mixture
A secret ingredient, peculiar to each vineyard, is added to the wine in order to increase or decrease sweetness. The proportions start from ‘extra brut’ (between 0 and 6g per litre) and end at ‘doux’ (sweet - more than 55g per litre).
- Inserting the cork
A key stage when making sparkling wines, the corking process must be a perfectly hermetically sealed procedure in order to guarantee that the product remains well preserved. Proper corks are used.
- Muzzling the bottle
In order to keep the cork in the bottle despite the carbon dioxide pressure, a wire muzzle and a cap are fixed on top.
- Shaking
After closing, the bottle is shaken vigorously to make sure that the contents are well mixed.
- Dressing the bottle
As the last stage, the bottle is kitted out to complete its clothing: main label, foil, neck collar, etc.
