Glass Fermentation Jars, 2 Gallon

Size & fit

For home fermenters and cooks who store ingredients in larger batches, these 2-gallon glass jars offer room for kombucha, pickles, fruit infusions, or pantry staples such as flour and sugar. The wide mouth is 4.3 inches across, which should make it easier to add ingredients, scoop them out, and reach inside when cleaning. Each jar measures 7.7 inches long by 6.6 inches wide by 12.2 inches high, so check your shelf and counter space before choosing a pair.

The set includes two jars, with detachable handles and silicone bases for each.

The square shape gives the jars flat sides rather than a round profile. That can be useful while washing one in a sink, where it is less likely to roll around. But these are still large glass containers, once filled, carrying one deserves more care than moving a small pantry jar. Without having tried it, the practical trade-off is clear: capacity is helpful for batch storage, while the size calls for a suitable place to keep and handle each jar.

Pros

The stainless steel screw-on lid has a food-grade silicone inner seal, designed to close tightly and help limit leaks and moisture. For dry goods, that sealing approach may be more reassuring than an open crock or a container with a loose-fitting lid. It also reduces direct contact with plastic, according to the product details.

A 4.3-inch opening makes the jars more accessible than narrow-neck containers when you’re adding fruit or removing fermented ingredients. The reinforced stainless steel handle is intended to make moving a filled jar easier, while the silicone base adds grip on smooth surfaces. Measurement markings in ounces and liters can also help when tracking liquid quantities or keeping a batch consistent. What’s more useful here: another small jar, or one container that holds a full batch and shows its measurements at a glance?

One limitation to keep in mind: the listing describes these as storage and fermentation jars, but does not specify pressure-canning use. If your goal is shelf-stable canning with a particular processing method, this listing alone doesn’t establish that the jars are suitable for it.

When it makes sense

Worth considering if you make kombucha or pickled vegetables in larger batches, or want a clear container for storing a substantial amount of flour or sugar. For example, the wide opening gives you room to add fruit for an infusion, then reach in to remove it without working through a narrow neck. The scale markings may help you keep track of liquid levels as you go.

It may not suit you if you need compact containers, have limited shelf clearance, or want a jar specifically confirmed for pressure canning. Compared with buying several smaller containers, this pair favors fewer, larger batches and visible quantities, smaller jars may be easier to lift, fit into tight spaces, or portion for everyday use. Choose these when capacity and access matter more than a compact footprint, and skip them if their height or filled size would make routine handling awkward.
