3-Piece Airlock – Fermentation Airlock for Beer, Wine, Cider & Mead

The Essential Tool for Fermentation Control

The 3-Piece Airlock is a must-have for any homebrewer or winemaker looking to protect their fermentation from contaminants. Designed to fit standard fermenters, this clear plastic airlock acts as a one-way valve—allowing CO₂ to escape while keeping air, bacteria, and wild yeast out.

Why Use a 3-Piece Airlock?

• Easy Cleaning: Comes apart for thorough sanitizing between batches.
• Clear Visibility: Transparent plastic makes fermentation activity easy to monitor.
• Durable Construction: Made from sturdy, food-grade plastic built to last.

Enhanced Protection with Star San

Fill the airlock with Star San (instead of water) to create an additional barrier against airborne contaminants:

• During Temperature Drops: Prevents air from being sucked back in as the internal pressure drops.
• Late Fermentation: Helps protect your brew when CO₂ production slows down.

Versatile Applications

Perfect for use with a wide range of fermentation projects:

• Beer
• Wine
• Mead
• Cider
• Kombucha
