Barrel Fermentation Bung
This bung allows natural carbon dioxide buildup from the fermentation process to be released from the fermenter barrel, without the concern of air entering the barrel. This allows the wine or beer to correctly ferment without the fear of air oxidation ruining your product. The two-piece design allows the fermentation lock to stay in the barrel, releasing pressure when necessary. The bung is made from 100% FDA approved, food grade pure silicone rubber.
- Prevents Access to Micro-Organisms - Vinegar bacteria, lactic bacteria, and weak wild yeasts are easily preventable with a properly maintained bung.
- Oxidation Prevention – Fermentation bungs also prevent oxygen from accessing your product during your wine making or beer brewing process. A fermenter silicone bung not only prevents oxidation, but it makes the production of alcohol possible.
- Proper Carbon Dioxide Ventilation – The main duty of a fermentation bung is to properly ventilate the fermenter without letting in oxygen.
Sanitary Features:
When overflow happens, the wine barrels including the bung, need to be thoroughly cleaned. The washing process often saturates the bung with water, which can be a problem for ordinary fermentation bungs. However, these bungs keep the water from collecting on the outside of the bung and potentially entering the barrel, they are ultra-sanitary and keep your product safe when properly used.
