Best Fermentation Jars
As an Amazon Associate I earn from qualifying purchases.
Most vegetable ferments never need a crock. A wide-mouth glass jar holds brine, takes a standard lid, and lets you watch the ferment instead of guessing at it. What varies is glass thickness, shoulder shape, mouth diameter, and how well the threads accept aftermarket airlock lids. Straight-sided jars pack tighter and clean easier than shouldered ones, and a wide mouth is the difference between packing cabbage comfortably and fighting it. We favored jars with consistent thread tolerances, since a lid that seals on one brand can weep on another. Thick bases and properly annealed glass matter for jars washed hot week after week. Quart jars fit a single batch of pickles or a small kraut and still sit in most fridge doors. Half gallons suit a weekly kraut habit. Pick the wide mouth unless you only ferment hot sauce mash or brine drinks.
