Half Gallon Mason Jar Wide Mouth 64 oz - Airtight Lid

In this review the kitchentoolz half gallon mason jars stand out as a practical choice for home fermenters and kitchen organizers who need a reliable, clear storage vessel. The single biggest reason to buy is the combination of a true 64 oz capacity with a wide 110mm mouth and foam-lined twist-on lids that make filling, scooping, and keeping contents fresh straightforward. For anyone brewing kombucha or keeping sourdough starter, these jars strike a balance between durability and everyday usability.

Key Features

• 64 oz capacity: The half gallon size offers ample room for kombucha, kefir, pickles, or larger sourdough starters without crowding or frequent transfers.
• Wide mouth 110mm: The 4 in opening allows easy access for filling, scooping, and cleaning, which is especially handy when working with solids or cloth covers during fermentation.
• Thick clear glass: Durable, polished glass gives clear visibility of contents so you can monitor fermentation or inventory at a glance.
• Foam-lined plastic lids: Twist-on lids with PE foam lining help preserve freshness and reduce leaks when storing liquids or dry goods.
• BPA-free food-safe materials: The plastic lids and glass are suitable for daily kitchen use and pantry storage with food safety in mind.
• Made in the USA: Domestic production brings consistent quality and attention to detail in both glass and lid fit.

Who It's For

The jars are ideal for home brewers making kombucha or kefir, bakers maintaining sourdough starters, and cooks who pickle vegetables or eggs. Their wide mouth and 64 oz volume suit anyone who needs easy access for stirring, straining, or scooping, and the clear glass helps with visual checks during fermentation.

Those who need vacuum-sealed long-term canning for pressure canning or metal two-piece lids with jar rings should look elsewhere; these jars are best used for refrigerated storage, fermentation, and dry pantry organization rather than heat-process canning.
