Bormioli Rocco's Fido squared wide mouth glass jar with airtight gasket clamp lid, a large 101.5 oz size.
Fido-style jars, the Italian gasket-sealed clamp jars, have a devoted following among vegetable fermenters for a simple reason: the rubber gasket vents excess CO2 on its own while keeping oxygen out, so you get airlock-like behavior with no extra hardware. No weekly burping ritual, no water-filled airlock to knock over. What varies is size, gasket quality, clamp tension, and whether the jar shape makes it easy to pack vegetables tightly and keep them submerged. We weighed seal consistency, gasket availability as replacements, mouth width for packing and weighting, and how sizes map to real batches, since a half-full jar leaves more oxygen headspace than ideal. The 1 liter jars suit small test batches and condiments like fermented hot sauce mash. The 2 and 3 liter sizes suit household sauerkraut and pickle production. Pair any of them with glass weights, because the jar solves gas exchange, not floating vegetables.
