Silicone wine barrel bungs are specialized stoppers used in winemaking to seal the openings of wine barrels. Our bungs are made from food-grade silicone, a durable and inert material that does not affect the wine’s flavor or quality. The flexibility of silicone allows for a secure, airtight seal, preventing contaminants from entering the barrel and spoiling the wine.

Breathable barrel bungs, also known as fermentation bungs, are a specialized bung designed to naturally raise and resettle as gases build up during fermentation activity, allowing the gases to release (or burp), while bung remains secure in the barrel, reducing risk of spoilage or contaminants.
