This reliable fermentation airlock made of durable PVC is an ideal accessory for making wine, cider, or homebrew beer. The large chambers reduce the evaporation rate, so the fermenter maintains the correct water level for longer. The airlock fits precisely into holes in rubber bungs for demijohns and enables smooth venting of carbon dioxide without allowing air to reach the beverage.
The material is approved for food contact (PZH certificate), ensuring process safety and cleanliness. Thanks to the visible water column, you can easily monitor fermentation intensity—from active bubbling to the resting phase.
