2 Pack Wide Mouth 1 Gallon Clear Glass Jar with Heavy Duty Airtight Screw Lid and Silicone Gasket Review (2026)

What comes in the pack

This listing includes two 1 gallon wide mouth clear glass jars, each with a heavy duty screw lid, plus two extra silicone gaskets beyond the ones already fitted to the lids. Having spare gaskets included is a practical detail, since gaskets are the part most likely to wear out or need replacing after repeated fermentation cycles, and not every jar listing includes backups. Each jar also has two scale marks molded into the glass, giving a rough visual reference for volume when filling a batch without needing to measure separately, which is useful for keeping brine ratios consistent across repeat batches over time.

How the sealed lid performs

The screw lid uses a silicone gasket to create a tighter seal than a plain metal or plastic lid without any gasket at all, which helps keep dust and insects out during storage and reduces the chance of slow leaks when the jar is moved or tilted. For storing a finished ferment, or holding liquid like kombucha between brewing steps, that tighter seal is a clear advantage over a looser-fitting lid. The gasket is also removable for cleaning, which matters since brine and fermented liquid can work into the seal area and leave odors behind if it is never taken apart and washed periodically between batches.

Why burping matters with this jar

An airtight gasket seal is good for storage but creates a real limitation during active fermentation, since a ferment that is still producing carbon dioxide will build pressure inside a fully sealed jar. Left completely closed for an extended active ferment, that pressure can make the lid difficult to unscrew or, in some cases, push liquid out around the seal when finally opened. Burping the jar regularly, meaning opening it briefly to release built-up gas, is the standard workaround for airtight screw-lid jars like this one during the active phase of a ferment, and it becomes less necessary once fermentation activity slows and gas production tapers off toward the end of the batch.

Sizing for kombucha and vegetable batches

A gallon is a substantial size, large enough to brew a full batch of kombucha or ferment a meaningful volume of shredded cabbage or cucumbers without needing multiple smaller jars running at once. The wide mouth opening makes packing vegetables in by hand easier than a narrow-necked jar would, and it also makes cleaning between batches simpler since a hand and brush can reach every corner. Two jars in one purchase is enough to run a kombucha batch in one and a vegetable ferment in the other, or to stagger two batches a few days apart.

Who should buy it

This set suits someone who wants gallon-sized glass jars for kombucha brewing or bulk vegetable fermentation and values a tight, gasket-sealed lid for storage once a batch is finished. It is best paired with a habit of burping the jar regularly during active fermentation, since the sealed design is not built to vent gas on its own the way a dedicated airlock lid would. Buyers who want a completely hands-off fermentation setup that vents automatically may prefer a jar fitted with an airlock lid instead of this screw-top gasket design, though many home fermenters find manual burping a small trade-off for a lid that also doubles as reliable long-term storage.
