Miniguysa Fermentation Lids – Self-Burping Airlock for Wide Mouth Jars (86mm) 5-Pack Rainbow

Upgrade Your Fermentation with Miniguysa Forever Lids

Transform your jar-based ferments with a one-piece, heavy-duty silicone lid designed for wide-mouth Mason jars (86mm). The 70g silicone body resists warping, provides a reliable seal, and minimizes dirt-trapping crevices. Crafted from 100% food-grade material and fully dishwasher safe, these lids are built to handle large batches of Sauerkraut, Kimchi, pickles, and other ferments without compromise.

• One-piece, 70g silicone construction for durability and a clean seal
• 100% food-grade silicone and dishwasher safe for easy cleanup
• Designed to reduce warping and avoid hidden dirt traps

Smart, Low-Fuss Fermentation

The waterless airlock valve automatically vents carbon dioxide while keeping oxygen and contaminants out. This means you can set it and forget it, reducing the need for daily burping or bulky external airlocks. It’s ideal for crisp sauerkraut, large dill pickles, and spicy kimchi where consistent airflow matters.

• Auto-venting waterless valve reduces manual monitoring
• Prevents oxygen intrusion while preserving aroma and texture
• Compatible with large batches and tall jars without clutter

Built-In Date Tracking for Easy Timeline Management

A rotatable date tracker is integrated into the lid. Pull the dial, set your start date, and snap it back into place. The durable design won’t fade or snap like cheaper plastics, keeping your fermentation timeline clear at a glance.

• Intuitive, durable date dial built into the lid
• Never rely on sticky labels or guesswork again
• Part of the lid, not an add-on accessory

Fridge-Friendly, Low-Profile Design

Say goodbye to tall, bulky airlocks. The flat-top, low-profile form fits comfortably on refrigerator shelves, so you can store jars upright without removing the lid or swapping parts. Once fermentation finishes, slide jars straight into the fridge with ease.

• Flat-top profile saves fridge space
• No need to swap lids after fermentation
• Smooth, easy-to-clean surface

Color-Coded 5-Pack for Easy Organization

Keep your ferments organized with five vivid colors. Use Red for spicy kimchi, Green for dill pickles, Orange for classic sauerkraut, and more—transforming your kitchen into a color-coded fermentation station.

• Five vibrant colors for quick sorting
• Consistent, reliable performance across all colors
• Perfect for a wide range of ferments in one kitchen

Compatibility note: These lids are designed for standard 86mm wide-mouth Mason jars. They’re ideal for large batches of krauts, pickles, kimchi, and other fermented foods, offering a practical upgrade over traditional multi-part lids without promising guaranteed results.
