YARWELL 1-Gallon Fermentation Jars 2-Pack — Wide-Mouth Glass with Clamp Lids & Water-Seal Airlocks

YARWELL 1-gallon fermentation jars with clamp lids and water-seal airlocks are a ready-to-use two-pack for small-batch kraut, pickles, kombucha, and vegetable ferments.

These two glass fermenters come complete with removable silicone gaskets, clamp-style lids, and three-piece water-seal airlocks so you can begin fermenting as soon as you unpack. The wide-mouth opening gives easy access for packing, stirring, and cleaning, while the included airlocks let CO₂ escape without letting oxygen back in — offering visual bubbling you can monitor during fermentation. Thick, lead-free glass and a design intended for everyday kitchen use help these jars bridge beginner-friendly convenience with reliable, reusable materials.

How do these jars make home fermenting simpler?

The kit arrives fully equipped so you don’t need to hunt down parts. Clamp lids with removable gaskets give a tight seal without fiddly screws, and the water-seal airlocks show active fermentation through visible bubbling.

• Two 1-gallon jars sized for family batches or experiment rounds
• Three-piece water-seal airlocks included and ready to fill
• Clamp lids for quick one-handed sealing and opening
• Removable silicone gaskets for easier cleaning and maintenance

Will the wide mouth and glass hold up during use?

The wide-mouth opening fits whole heads of cabbage or large vegetable portions, so you can pack and press ingredients by hand. The jars are made of thick, lead-free glass intended for regular kitchen use; lids should be hand-washed to protect gaskets while jars themselves are dishwasher-safe.

• Wide mouth accommodates full cabbage and hand packing
• Thick, food-grade, lead-free glass for durability
• Dishwasher-safe jar bodies; hand-wash lids and gaskets
• Sanitize by boiling jars (avoid thermal shock)

How do the airlocks work and what maintenance do they need?

The included three-piece water-seal airlocks let carbon dioxide exit while blocking oxygen and contaminants from entering. You’ll see bubbles as CO₂ escapes — a simple visual cue that fermentation is active. Keep the water level topped up and rinse the airlock between batches for best performance.

• Fill airlocks halfway with water before starting a batch
• Visible bubbling confirms gas release during fermentation
• Top up water every few days if evaporation occurs
• Disassemble and rinse airlocks when finished to prevent residue

What can I safely ferment and how much will one jar hold?

Each 1-gallon jar is ideal for family-sized sauerkraut, small kimchi batches, lacto-fermented pickles, or kombucha starter vessels. The capacity matches common small-batch recipes so you can scale without wasting ingredients, and the wide mouth makes transferring and removing solids straightforward.

• About one family batch of sauerkraut or a full kombucha mini-brew
• Works well for pickles, relishes, kimchi, and vegetable ferments
• Wide opening simplifies adding or removing produce
• Two jars let you stagger batches or compare recipes

Who this is for: home fermenters who want a complete, no-fuss starter kit—especially beginners who appreciate visual fermentation indicators and easy-to-clean parts—as well as experienced hobbyists who need reliable 1-gallon vessels for recipe testing and small family batches. The pair of jars suits cooks who want to run two different ferments at once or keep one jar active while the other is in use, all without hunting for separate lids or airlocks.
