Folinstall Fermentation Jar Set 1.5 Gallon (2-Pack) — Leak-Proof Glass Jars with Airlocks & 4.3-inch Wide Mouth

Folinstall 1.5 Gallon Fermentation Jar is a complete, leak-proof glass kit designed for fermenting kombucha, pickles, mead, sourdough starter and dry storage with accurate measuring marks and durable hardware.

If you make fermented foods or homebrew, having a jar that seals tightly, resists slips, and lets you monitor volumes matters. The Folinstall kit pairs two 1.5 gallon glass vessels with stainless-steel handles, silicone bases, airlocks and clear scale markings so you can focus on recipes and timing instead of worrying about spills or unclear measurements.

How does the Folinstall jar keep ferments safe and clean?

The jar uses a multi-point sealing system: a thickened silicone gasket, a secure metal clasp, and a silicone plug with an included airlock. This assembly reduces exposure to airborne contaminants while allowing controlled gas release during active fermentation.

• Thick silicone gasket forms a tight barrier against liquid leaks and outside air
• Metal clasp locks the lid firmly in place for reliable sealing
• Silicone plug plus airlock vents CO2 while limiting oxygen contact
• Removable components make sanitizing and maintenance straightforward

What makes this jar practical for measuring, filling and cleaning?

Each jar is molded with clear Ml and Fl.oz scale markings to track batches and ingredient volumes without relying on separate measuring tools. A 4.3-inch wide mouth simplifies filling, stirring and thorough cleaning, while the included silicone base supports stability on countertops.

• Dual measurement scales (metric and imperial) printed on the glass
• Wide 4.3" opening for scooping starters, adding vegetables, or pouring liquids
• Silicone base prevents scratches and slips during active use
• Glass interior resists staining and retains neutral flavor

Are these jars robust enough for repeated homebrewing and storage?

Folinstall jars are built from thick glass and fitted with stainless-steel handles to support lifting full batches safely. The design anticipates repeated use: durable materials, easily replaceable silicone parts, and a thoughtful shape that balances capacity and countertop footprint.

• High-quality glass resists thermal and chemical wear typical in fermentation
• Stainless-steel handles provide secure transport and pouring control
• Silicone parts cushion the base and help protect surfaces
• Dimensions optimized for home kitchens at 6.5" x 6.5" x 11.8"

The set includes two 1.5 gallon glass jars, two silicone bases, three airlocks, two stainless-steel carrying handles, two instruction manuals and replacement plugs. That combination gives you everything to start fermenting immediately, whether you’re working with sourdough, mead, kombucha or vegetables.

• Two glass fermenters (1.5 gallon each) ready to fill
• Three airlocks for one-way gas release during fermentation
• Two durable silicone bases to protect surfaces and steady jars

It’s suitable for beginners who appreciate a ready-to-use kit and experienced makers who need durable jars to run multiple batches.
