PRODUCT UNAVAILABLE
An essential complement to a demijohn is a properly fitted rubber stopper with a fermentation airlock or a natural cork stopper.
Product characteristics:
The available stoppers are PZH-certified for contact with food. The stoppers are equipped with an opening in which a fermentation airlock (glass or plastic) can be installed. Made of PVC.
Use
Synthetic stoppers for demijohns - before use, it is recommended to wash them thoroughly in warm water with dishwashing liquid, then dry them thoroughly. This is intended to remove the layer of silicone remaining from the production stage, which may contribute to the stopper being pushed out of the demijohn during fermentation or slipping off in the case of rubber caps.
