- Méthode Champenoise / Méthode Traditionnelle
- Transfer method
- Metodo Italiano (Charmat process)
In the Charmat process, the entire second fermentation process is done in a large pressurized tank. The result in this process is that the carbon dioxide has less time to integrate with the wines so there are larger bubbles that dissipate faster. Usually prosecco is made using this process (hence the name).
