méthode champenoise

The term "méthode champenoise" refers to a specific method of producing sparkling wine, most famously associated with Champagne from the Champagne region of France. This method involves a secondary fermentation that occurs directly within the bottle.12

Here's a breakdown of the process:
* Primary Fermentation: Grapes are pressed, and the juice undergoes its initial fermentation to produce a still wine.1
* Blending: Wines from different grapes or vintages may be blended to achieve a desired flavor profile.1
* Secondary Fermentation: A mixture of sugar and yeast is added to the wine, and it is bottled under pressure. This induces a second fermentation, creating carbon dioxide that dissolves into the wine, resulting in effervescence.32
* Aging and Riddling: The wine ages in the bottle, often for years, in contact with the yeast sediment. The bottles are then gradually turned and tilted to consolidate the sediment near the cork.2
* Disgorging: The sediment is removed, often by freezing the neck of the bottle and then allowing the internal pressure to expel the frozen yeast plug.2
* Dosage: A small amount of wine and sugar (dosage) is added to adjust the sweetness before the bottle is corked and wired.2

This traditional method, also known as classic bottle fermentation, is distinct from tank fermentation or direct carbonation.245
