FastRack 1-Gallon Glass Jugs 4-Pack — Clear Homebrew Fermentation Kit with Airlocks & Polyseal Caps

FastRack’s 4-pack of 1-gallon clear glass jugs comes ready for fermentation with drilled rubber bungs, 3-piece airlocks and airtight polyseal caps for homebrew and storage use.

These 128 oz (3.8 L) clear glass jugs are designed for small-batch brewing, fermentation, and reliable liquid storage. Each kit includes one drilled #6.5 rubber bung and a 3-piece airlock to let CO2 escape while keeping oxygen and contaminants out, plus a screw-on polyseal cap for sealed transport or long-term storage. The reusable glass construction gives you a non-reactive, easy-to-clean vessel ideal for everything from wine and mead to kombucha and extract-based beers.

How are these jugs set up for fermentation?

Every jug arrives ready to ferment: a pre-drilled #6.5 rubber bung fits snugly into the neck, and the included 3-piece airlock snaps into the bung to allow safe gas release. The combination controls headspace exposure and reduces the risk of airborne contamination without complicated assembly.

• One drilled rubber bung per jug (#6.5 size).
• 3-piece airlock for visible bubbling and pressure relief.
• Polyseal screw cap for sealed storage or shipping.
• Clear glass body for visual monitoring of activity and clarity.

What liquids and projects are these jugs best suited for?

These glass jugs are multi-purpose vessels for small-batch fermentation, steeping, tinctures, and safe food-grade storage. Their size is well matched to test batches or for finishing primary fermentation before transferring to secondary containers or bottles.

• Homebrew beer, small wine or mead batches.
• Cider, kombucha, and fermented sodas.
• Ingredient infusions, extracts, and long-term liquid storage.
• Sampling, labelling, and recipe iteration for brewers.

How do I care for and reuse these glass jugs?

Glass is non-porous and resists staining and flavor retention, making it simple to sanitize and reuse. Clean with brewery-safe cleaners, rinse thoroughly, and allow to air-dry; the polyseal caps and rubber bungs can be removed for separate sanitation.

• Hand-wash or use a gentle cycle; avoid extreme thermal shock.
• Use a soft brush for the neck and interior to reach residues.
• Sanitize bungs and airlocks before each fermentation cycle.
• Store capped and dry to prevent odors or dust buildup.

Will these fit my existing homebrew accessories?

The jugs use standard homebrew fittings: the #6.5 drilled bung and the 3-piece airlock conform to common sizes, and the polyseal cap screws on for transport or storage. They’re compatible with most siphons, tubing and transfer tools used in small-batch operations.

• Standard #6.5 bung size compatible with common airlocks.
• Fits small-diameter racking hoses and siphons for easy transfers.
• Polyseal cap secures contents for shipping or fridge storage.
• Transparent walls work with hydrometers and visual gravity checks.

Who is this for? FastRack’s 1-gallon 4-pack is aimed at homebrewers, hobby vintners, fermentation hobbyists and anyone who wants a reusable, clear glass container for small-batch liquids. It’s especially useful for recipe testing, small-volume fermentations, and those who prefer glass over plastic for flavor neutrality and sustainability. If you make wine, mead, kombucha, cider or experimental brews and need dependable vessels that come ready with bungs and airlocks, this kit gives you four clean, clear, reusable jugs to work with.
