Fermentation Accessories

How to choose wine fermentation accessories

Different fermentation accessories are used for different tasks, including gas release, container closure, topping up and handling must or wine.

The correct choice depends mainly on the type of container, the diameter of the opening and the function the accessory needs to perform. Always check the dimensions and intended use shown on the individual product page before ordering.

Wine airlocks, bungs and mini fermenters

A fermentation airlock allows carbon dioxide produced during fermentation to escape while helping limit direct contact between the contents of the container and the surrounding air.

Wine airlocks can be used together with suitable bungs or stoppers, depending on the container. Before purchasing, check the diameter of both the stopper and the opening to make sure the components are compatible.

Mini fermenters are also available for specific container configurations. As with airlocks and bungs, compatibility and dimensions should always be checked on the product page.

Rubber caps, silicone stoppers and topping-up accessories

Rubber caps, silicone stoppers, topping-up devices and topping-up holders are used for closing containers or completing the topping-up system.

The most important factor when choosing these accessories is the size and type of the container opening, so compare the measurements provided with the dimensions of your demijohn, barrel or other wine container.

Wine lifters, baskets and grape collecting funnels

This category also includes accessories used for moving or collecting must and wine during cellar work, such as wine lifters, must draining baskets and grape collecting funnels.

Because these products perform different functions, always check the individual product description to make sure the accessory is suitable for the operation you need to carry out.

Fermentation accessories or wine treatment products?

This category is dedicated mainly to physical accessories for fermentation and container management. If you are looking for yeasts, fermentation aids, clarifying agents, sulphiting agents, stabilisers or other products used directly on must and wine, browse our Wine Treatment & Winemaking Supplies section.

Need a wine tank rather than an accessory?

If you need a complete container rather than an airlock, bung or stopper, you can also explore our Variable Capacity Wine Tanks. This keeps the choice of fermentation accessories separate from the selection of complete wine tanks.
