1 Gallon Jar Lid

Replace or upgrade your fermentation setup with the 1 Gallon Jar Lid, a secure, airlock-ready lid designed specifically for Craft a Brew fermentation jars. This lid provides a tight fit and proper airflow control, helping maintain clean, stable fermentation conditions in one-gallon batches.

The 1 Gallon Jar Lid is intended for brewers and fermenters using Craft a Brew Hard Seltzer Kit jars who need a reliable replacement or spare lid. It allows carbon dioxide to escape while preventing oxygen and contaminants from entering the fermenter, supporting consistent fermentation performance.

This lid features a pre-installed grommeted hole designed to hold a standard airlock securely in place. It is sized to fit Craft a Brew one-gallon brewing jars and is not compatible with kombucha fermentation jars, which use a different lid design.

For best results, ensure the lid is fully seated on the jar and that the airlock is properly installed and filled before fermentation begins. Clean and sanitize the lid prior to each use to maintain optimal fermentation conditions.

Designed for dependable performance and compatibility, the Craft a Brew 1 Gallon Jar Lid provides a practical solution for maintaining or restoring your one-gallon fermentation setup.
