Dégorgement à la Glace

Dégorgement à la Glace: A comprehensive overview

Das „Dégorgement à la Glace“ ist eine bedeutende Technik in der Champagnerherstellung, die maßgeblich zur Qualität und Reinheit des Endprodukts beiträgt. Diese Methode, die auf Deutsch „Eis-Degorgieren“ bedeutet, spielt eine zentrale Rolle im Prozess der Herstellung von hochwertigem Champagne. Sie wird verwendet, um die Hefe, die sich während der sekundären Gärung in der Flasche gebildet hat, zu entfernen, und sorgt für einen klaren, feinen Champagner. In diesem Artikel werden die Details dieser Technik, ihre Geschichte und ihre Bedeutung für die Champagnerproduktion umfassend beleuchtet.

The process of Dégorgement à la Glace

1. Secondary fermentationChampagne undergoes secondary fermentation in the bottle after a mixture of sugar and yeast has been added to the base wine. This leads to the formation of carbon dioxide and fine yeast particles that remain in the bottle during storage.
2. Shake (Remuage)To move the yeast particles into the neck of the bottle, the champagne is regularly shaken and turned. This process, known as remuage, ensures that the yeast is concentrated in the neck of the bottle.
3. Freezing the neck of the bottleDégorgement à la Glace involves immersing the neck of the bottle in a freezing bath at a temperature of around -25 to -30 degrees Celsius. This causes the yeast and the remaining sediment to freeze in the form of a solid yeast plug.
4. Removing the yeast plugAs soon as the yeast is frozen, the bottle cap is removed. The pressure of the carbon dioxide causes the frozen yeast plug to be ejected from the neck of the bottle, leaving the champagne clear and free of yeast particles.
5. Closure and dosageAfter dégorgement, the bottle is sealed with a cork and a small amount of dosage, a mixture of wine and sugar, is often added to achieve the desired degree of sweetness.

History and development

Dégorgement à la Glace has its origins in the 19th century, when champagne production became increasingly sophisticated. The method was developed to efficiently remove the yeast from the bottle and improve the clarity of the champagne. Before the introduction of dégorgement à la glace, the yeast sediment was often removed by other methods that were less precise and often less effective.

The introduction of ice disgorging revolutionised champagne production by enabling a much cleaner and more elegant presentation of the champagne. This technique is particularly important for high-quality champagnes, where the clarity and purity of the drink are of the utmost importance.

Significance for champagne quality

Dégorgement à la Glace contributes significantly to the quality of the champagne. It not only removes the yeast particles, but also minimises the risk of oxidation and changes in flavour that could be caused by the residual yeast. The precise removal of the yeast ensures that the champagne retains its fine flavours and sparkling freshness.

In addition, dégorgement à la glace enables a consistent and uniform quality of champagne as it provides precise control over the lees removal process. This is particularly important for prestige champagnes, where every detail counts.

Challenges and costs

Although dégorgement à la glace offers many benefits, it also comes with challenges and costs. The technique requires specialised equipment and expertise to ensure that the process is carried out correctly. The freezing of the bottle necks and the precise removal of the yeast plug require both technical expertise and careful handling.

The cost of dégorgement à la glace can be higher than other methods of lees removal, which is usually reflected in the price of the final product. For many champagne producers, however, this investment is justified as it contributes to an outstanding product that is appreciated on the market.

Conclusion

Dégorgement à la Glace is an indispensable technique in Champagne production that ensures that the Champagne is presented in its purest and clearest form. The method has proven to be particularly effective in removing the yeast particles while preserving the delicate flavours and freshness of the champagne. Despite the higher cost and technical challenges, dégorgement à la glace remains a favoured method for producing top quality Champagne and is an essential part of the artistry that goes into making a premium Champagne.
