About This

• Complete All-in-One Fermentation Kit — Start Fermenting Immediately This 2-pack includes everything you need: two 1-gallon wide-mouth glass jars, two 3-piece airlocks, two glass fermentation weights, silicone grommets, and replacement seals. No need to buy accessories separately. Just add vegetables, salt, and water — your first batch of sauerkraut, kimchi, or pickles is ready to start the moment you unbox.
• Glass Weights Keep Ingredients Submerged — Proper Brine Coverage, Better Results The included glass weights press cabbage, cucumbers, and other ingredients below the brine line — the single most important factor for properly submerged fermentation. Each jar comes with one weight. For recipes with large vegetable pieces that tend to float, you can stack both weights in a single jar for extra holding power. No more fishing out floating top layers.
• 3-Piece Airlock — Automatic Gas Release, No Daily Burping Required The water-filled airlock vents carbon dioxide automatically while creating a sealed environment that keeps outside air from entering the jar. This means you can set it and forget it — no daily lid-burping routine. Note: when opening the jar mid-fermentation to check progress or add ingredients, remove the airlock first to avoid spilling the water inside it, then reattach after closing.
• Clear Lead-Free Glass — Monitor Fermentation Progress at a Glance Made of clear, lead-free glass designed for food contact. The transparent walls let you watch your ferment develop without opening the jar — check brine levels, observe bubble activity, and monitor color changes throughout the process. For best results, wash by hand with warm soapy water. If you choose to prepare the jar with boiling water, always let it cool naturally before use; sudden temperature changes (thermal shock) can crack any glass container, not just this one.
• 1 Gallon Wide-Mouth Jars — Big Batches, Easy Packing, Simple to Clean Each jar holds 1 gallon (3.8 liters) — enough capacity for roughly three shredded cabbages in a single batch of sauerkraut. The wide 4.25-inch mouth lets you pack vegetables tightly with your fist for proper brine extraction, and your whole hand fits inside for cleaning. Suitable for sauerkraut, kimchi, dill pickles, kombucha, mead, cider, sourdough starter, and lacto-fermented vegetables of all kinds.
