Bormioli Rocco Fido Squared Wide Mouth Glass Jar with Airtight Gasket Clamp Lid, 67.75 oz Review (2026)

Who this size of Fido jar fits

At 67.75 oz, roughly two liters, this jar is sized to hold a full head of cabbage's worth of sauerkraut or a generous batch of kimchi in one vessel, while staying somewhat easier to handle than the largest 101.5 oz jar in the same squared Fido line. It suits a fermenter who wants a complete batch in a single jar without stepping all the way up to the biggest size, and who has fridge or pantry shelf space that can accommodate a jar measuring roughly 5 inches across and 8.5 inches tall with the lid engaged. Someone fermenting smaller side-dish quantities will find this size larger than needed and should look at the 33.75 oz or 50.75 oz options instead, while a household regularly going through large batches of fermented vegetables may still prefer stepping up to 101.5 oz.

The airtight seal and build in detail

Bormioli Rocco is an Italian glassware maker, and every Fido jar in this line is manufactured in Italy with the same airtight system: a rubber gasket seated under the lid paired with a stainless steel wire clamp that presses the lid down evenly around the rim. That combination is what makes Fido jars a common choice for vegetable ferments like sauerkraut or kimchi, since the gasket lets built-up carbon dioxide vent past the seal under pressure during active fermentation while still blocking oxygen from reaching the ferment the rest of the time. The wire clamp is stainless steel rather than plated metal, which matters for anyone fermenting in brine, since splashed salt water is what corrodes cheaper clamps over repeated use. The glass body is dishwasher safe, but Bormioli Rocco and most retailers recommend hand washing the rubber gasket and clamp assembly separately to keep the seal in good condition for longer.

Living with this jar through active fermentation

The wide mouth makes packing a full head of shredded cabbage manageable, and pressing the vegetables down by hand to release enough brine to fully submerge them is easier here than in a narrow-neck jar of similar volume. As fermentation becomes active, the gasket does its job letting built-up gas escape past the seal without needing to manually burp the jar, though it should be checked periodically for stretching or cracking, since a worn gasket is the most common point of failure in this jar style and Bormioli Rocco sells replacements separately. Once full of brine and vegetables, the jar becomes heavy enough that lifting it out of a lower cabinet or fridge shelf takes some care, so many fermenters find it easier to ferment on a counter at room temperature and only move the jar to the fridge once fermentation has slowed.

How the 67.75 oz size compares with the rest of the line

This size sits between the 50.75 oz and 101.5 oz jars in Bormioli Rocco's squared Fido lineup, offering meaningfully more room than the mid-size jar without the bulk and weight of the largest option. Against the 33.75 oz two-pack, one 67.75 oz jar holds close to the combined volume of both smaller jars, which suits a single large batch rather than two separate smaller ones. Compared with Le Parfait's 2L Super Jar, which holds a very similar 64 oz using a wire bail closure instead of a clamp, the two are close competitors in capacity, with the choice mostly coming down to preference between the classic Fido clamp and the French bail-closure style.

Verdict and who should size up or down

This 67.75 oz jar is a good fit for a fermenter who wants a full cabbage's worth of kraut or a generous kimchi batch in one jar without committing to the largest size in the line, and who has the shelf space and arm strength to manage a heavy full jar. The seal performs the same as every other size in the Fido range, so the decision comes down entirely to batch size and storage space. Anyone fermenting smaller quantities should choose the 33.75 oz or 50.75 oz jar instead, and anyone consistently processing very large batches should consider the 101.5 oz size. A separate fermentation weight is still needed, as none of the sizes in this line include one.
