YARWELL 1 Gallon Fermentation Kit — 2-Pack Wide-Mouth Glass Jars with Weights & Airlocks

The YARWELL 1 Gallon Fermentation Kit 2-pack is a ready-to-use set of wide-mouth glass jars, fermentation weights, 3-piece airlocks, and silicone seals designed to make small-batch lacto-fermentation simple and reliable.

If you want to ferment vegetables at home without hunting down parts, this pair of 1-gallon jars bundles the most important components into one kit. The clear, food-grade glass jars let you observe brine and bubbling activity, while the included weights and airlocks help maintain an oxygen-restricted environment so your ferments can develop consistently. Everything fits together out of the box — just add your produce, salt, and water.

How do these jars keep vegetables submerged?

Maintaining full brine coverage is essential for safe, flavorful fermentation. Each jar includes a shaped glass weight that sits directly on top of packed vegetables to press them beneath the liquid layer and reduce the risk of surface mold.

• One glass weight per jar sized to fit the 1-gallon wide mouth.
• Weights can be stacked in a single jar for bulky pieces that float.
• Transparent glass makes it easy to confirm brine coverage at a glance.

What does the 3-piece airlock do and how do I use it?

The included three-piece airlocks let carbon dioxide escape while preventing outside air and contaminants from entering the jar. Fill the central chamber with water, insert it into the silicone grommet, and the system vents gas automatically so you don't need to burp the lid daily.

• Water-sealed venting avoids oxygen exposure and reduces spoilage risk.
• Simple assembly: grommet, airlock, and water — then set and monitor.
• Remove the airlock before opening the jar during fermentation to prevent spills.

Are these jars suitable for different ferment projects?

The 1-gallon capacity and wide 4.25-inch opening make these jars versatile for many small-batch ferments. They accommodate shredded cabbage for sauerkraut, layered kimchi, pickles, and even starters like sourdough or small kombucha brews.

• Holds roughly three shredded cabbages in one batch of sauerkraut.
• Wide mouth allows fist-packing and easy cleaning by hand.
• Clear lead-free glass provides visual monitoring without opening the jar.

How do I care for the glass and accessories?

These components are designed for repeated home use with basic cleaning and handling precautions. Hand washing with warm, soapy water is recommended; avoid sudden temperature changes to prevent thermal shock to the glass.

• Wash jars and weights by hand for longevity; airlocks can be rinsed thoroughly.
• Allow jars to cool naturally if rinsed with hot or boiling water.
• Store silicone gaskets and grommets dry when not in use to prevent odors.

Who is this for: Home cooks, fermentation beginners, and experienced preservers who want an all-in-one solution for small-batch ferments will benefit from this YARWELL 2-pack. It suits apartment kitchens and countertop projects where simplicity, visibility, and consistent results matter. If you need larger commercial volumes or jar-style crocks, consider larger containers, but for everyday sauerkraut, kimchi, pickles, and starters, this kit provides the essential tools to begin and repeat successful ferments with minimal fuss.
