Description

Ensure a reliable, airtight seal during fermentation with our  moulded rubber stopper with hole, designed specifically for winemaking and fermentation use.

All of our stoppers are injection-moulded, ensuring perfect consistency, durability, and fit from piece to piece. Made from BPA-free, food-grade materials, these stoppers are safe for use with wine, cider, beer, and other fermented beverages.

They provide an airtight seal essential for proper fermentation, fitting securely into both glass and PET carboys. The material grips exceptionally well — even when wet — though for the best possible seal, we recommend inserting the stopper when both the carboy neck and stopper are dry.

Quality is comparable to silicone stoppers, offering excellent flexibility, longevity, and sealing performance at a great value. The moulded hole is ideal for use with airlocks and fermentation accessories.
