Fermentation Jar 1 Gallon 2 Pack with Airtight Screw Lids - Wide Mouth

In this review of the 1 gallon fermentation jar 2 pack, the bottom line is simple: it is best for home fermenters who need roomy, durable glass containers that seal well for small-batch brewing and pickling. The reviewer found the super wide mouth and included airtight screw lids with silicone grommets make filling, stirring and fitting an airlock easy, while the extra airlock and spare grommets add practical backup for multi-batch use. For anyone making sourdough starter, sauerkraut, kombucha or fruit wine on a modest scale, these jars deliver convenience and peace of mind.

Key Features

• Super wide mouth: A 4.3 in opening makes scooping, measuring and cleaning far easier than narrow jars, which helps with starters and packed vegetables.
• 100% airtight lid: The screw-up lid includes a built-in silicone gasket that creates a secure seal to reduce spills and limit unwanted oxygen exposure during fermentation.
• Airlock ready: Each lid accepts silicone grommets and the set includes three airlocks so you can ferment with a one-way vent without transferring contents.
• Durable glass: Thick food-grade glass stands up to repeated use and is dishwasher safe for easy sterilizing between batches.
• Measured markings: Clear milliliter and fluid ounce scale marks remove guesswork and let you track batch volume without extra tools.
• Complete kit: The package includes two jars, extra grommets, three airlocks, two chalkboards and a pen so jars arrive ready to label and use.

Who It's For

This set is aimed at hobby fermenters and small-batch home brewers who want dependable, reusable glass jars with a wide mouth for easy access. It is especially useful for those making sourdough starter, pickles, small fruit wines, mead or sauerkraut where a reliable airlock and an airtight seal matter.

It may not be ideal for industrial or very large-batch makers who need multi-gallon vessels, nor for people who prefer metal or plastic fermenters for their light weight. If you need dozens of containers or need a built-in spigot, look for larger specialized kits instead.

Pros & Cons

Pros

• Wide 4.3 in mouth simplifies filling, stirring and cleaning compared with narrow jars.
• Airtight screw lid with silicone gasket provides a reliable seal to contain brine and reduce leaks.
• Includes three airlocks and spare grommets so you can run multiple batches without improvising parts.
• Thick, measured glass is dishwasher safe and convenient for tracking small volumes.

Cons

• Durability feedback is mixed from users, so while glass is thick some buyers report concerns about long term wear or breakage in rough handling.
• Square mason shape may take more shelf space than cylindrical fermenters for the same volume.
