North Mountain Supply 1-Gallon Glass Fermenting Jug Set of 4 — 38mm CT, Handles & Airlocks

Four clear 1-gallon glass fermenting jugs with handles, 38mm CT screw tops, stoppers, 6-bubble airlocks, lids, and a cleaning brush — a complete home fermentation kit.

These North Mountain Supply jugs are designed for small-batch fermentation and storage, offering durable American-made glass, user-friendly handles, and hardware to start fermenting right away. Each jug has a continuous thread 38mm finish that fits the included black screw lid and standard number 6.5 rubber stopper with a six-bubble airlock. The set arrives with accessories and a long-handle cleaning brush so you can rinse, sanitize, and reuse the jars for brewing beer, making kombucha, testing yeast starters, or keeping solutions on hand.

How do these jugs handle everyday fermentation and pouring?

The integrated handle and one-gallon size make these jugs practical for repeat use and easy transfer. The clear glass lets you monitor fermentation color and activity, while the screw finish accepts the included lids for secure storage.

• One-gallon capacity balances batch size and fridge/storage fit
• Sturdy molded handle for controlled pouring and lifting
• Clear glass provides good visual monitoring during fermentation
• 38mm CT finish ensures consistent sealing with supplied lids

What accessories are included and why do they matter?

Each jug ships with a number 6.5 rubber stopper, a six-bubble airlock, and a black plastic screw lid—plus a long cleaning brush for maintenance. Those accessories let you set up an airlock seal or use a secure lid for storage or transport without needing extra purchases.

• Number 6.5 rubber stoppers for a snug fermenting seal
• Six-bubble airlocks to vent CO2 while minimizing oxygen and contaminants
• Black 38mm plastic screw lids for leak-resistant storage or secondary use
• Long-handled brush reaches the jug base for thorough cleaning

Are these jugs compatible with other equipment and how durable are they?

The 38mm continuous thread finish matches many common caps and accessories, and the jugs are made from thick glass suitable for repeated home use. Treat them like standard lab or food-grade glassware—avoid thermal shock from extreme temperature changes.

• 38mm CT finish fits many aftermarket caps and filters
• Thick, clear glass resists routine wear and is reusable
• Not designed for sudden temperature shocks—room-temp liquid and gentle heating only
• Made in USA; 30-day replacement policy for damage or defects

How do I clean and maintain the jugs so they last?

The included long-handle cleaning brush simplifies reaching the jug bottom and neck; pair with a non-abrasive cleaner or sanitizer for best results. Rinse well, let dry fully before storing, and replace rubber stoppers if they show wear.

• Use the long brush to scrub the base and neck without scratching
• Sanitize before and after fermentation for consistent results
• Allow full air-drying to prevent trapped moisture and odors
• Keep spare stoppers and airlocks on hand for repeated batches

Who is this for: Homebrewers, kombucha makers, experimenters testing yeast starters, and anyone needing reliable one-gallon glass containers for food-safe storage will appreciate this kit. The set is sized for countertop projects and small-batch fermentation, and the included hardware and brush let beginners start immediately while offering durability for more experienced fermenters.
