Quality Airlock for Wine and Cider Making

Reliable 2-bubble airlock that ensures perfect fermentation for 1-50 liter containers. Fits comfortably into a 9 mm opening, providing optimal protection against flies, oxidation, and contamination.

How the Airlock Works

The water in the siphon creates a hermetic seal that allows fermentation-produced carbon dioxide to escape while preventing air from entering. This ensures quality fermentation of your wine or cider.

Maintenance and Use

  • Regular water level monitoring is necessary due to evaporation
  • Option to use sanitizing solution instead of water
  • Recommended to check water level once a week

Due to its proven reliability and efficiency, this airlock is the most popular choice among home winemakers.

Frequently asked questions about 9000651

What hole does this fermentation lock fit into?

The fermentation lock fits into a 9mm opening, making it compatible with most standard rubber stoppers and silicone seals used in home winemaking. It works reliably in containers from 1 to 50 liters.

Should I fill the fermentation lock with water or disinfectant?

Both options work. Clean water is the traditional choice, but a diluted disinfectant solution (such as sulfite or StarSan) provides additional protection against bacterial contamination when vapors are drawn back during cooling.

How often should I check the water level?

We recommend checking the water level at least once a week. Evaporation is normal, especially in warm rooms, and a dry fermentation lock offers no protection against oxidation or airborne contamination.

Why is the 2-bubble design better?

The 2-bubble chamber design provides a visible indicator of fermentation activity and offers a more stable water seal than single chamber models. It also reduces the risk of water being sucked into the fermenter during pressure changes.
