The Essential Tool for Fermentation Control

The 3-Piece Airlock is a must-have for any homebrewer or winemaker looking to protect their fermentation process from outside contaminants. Designed to fit securely on most fermenters, this clear plastic airlock acts as a one-way valve, allowing carbon dioxide (CO2) to escape while preventing air, bacteria, or wild yeast from entering your fermenter.

Why Use a 3-Piece Airlock?

The 3-piece design offers several advantages over other airlock styles:

  • Easy Cleaning: Disassembles into three parts, making it simple to clean and sanitize between batches.
  • Clear Visibility: The transparent plastic allows you to easily monitor fermentation activity.
  • Durable Construction: Made from sturdy, food-grade plastic for long-lasting performance.

Enhanced Protection with Star San

We recommend filling the airlock with Star San instead of water for improved protection during fermentation. Star San creates an added barrier against airborne contaminants, especially in critical scenarios like:

  • Temperature Drops: A rapid decrease in temperature inside the fermenter can create a vacuum, pulling air through the airlock. Star San ensures no contaminants enter during this vulnerable period.
  • Low CO2 Generation: As fermentation slows, CO2 production diminishes, reducing the fermenter’s natural defense. Star San further safeguards your brew during this stage.

Versatile Applications

This airlock is suitable for a wide variety of fermentation projects, including:

  • Beer
  • Wine
  • Mead
  • Cider
  • Kombucha

How to Use the 3-Piece Airlock

  1. Fill the Airlock: Add Star San or clean water to the fill line.
  2. Attach to Fermenter: Insert the airlock into the fermenter lid or stopper. Ensure a tight seal to maintain proper pressure.
  3. Monitor Activity: Observe the bubbling to track fermentation progress.
