 Closed-top FermentorsClosed-top fermentors are any vessel that can be sealed or closed off from the outside environment. These are left with only a soft seal during the fermentation process that allows the carbon dioxide gas to escape while preventing unwanted oxygen from entering. This is the most common type of container used for fermenting. They function well for wine styles that use pumpovers as the primary form of cap management, and are recommended for wines that will undergo extended maceration. Closed-top fermentors can subsequently be used as storage containers afterwards, with a firm seal that prevents air from contacting the wine, and helps prevent any spoilage or oxidation that may occur in an open vessel. Any white or rosé wine that is not barrel fermented should be in a closed-top fermentor.
