Fermentaholics KrautKeeper™ is a simple tool that makes brine ferments easier and more reliable by keeping vegetables fully pinned below the surface. Once it’s in place, the flexible disk acts as both a follower and a weight, applying even pressure across the entire jar so shredded cabbage, kimchi mixes, pickle spears, and other vegetables stay securely under brine throughout fermentation. Keeping everything below the brine line helps limit oxygen contact, which supports cleaner, more consistent results batch after batch.
KrautKeeper is designed for larger batches in half-gallon and gallon jars, specifically those with a 6.3-inch inner diameter. It fits Fermentaholics gallon jars and standard 110 mm lid-opening half-gallon and 1-gallon jars. The food-safe silicone disk stays firmly in place during fermentation, and the built-in handle makes it quick to lift out when you’re ready to taste, pack, or serve. Afterward, just wash it with soap and water or run it through the dishwasher, then reuse it for your next ferment.


Designed for long-term use, this silicone weight is easy to rinse or toss in the dishwasher. Simple, reusable, and low-maintenance for your kitchen routine.


No more floating veggies or spoiled ferments. The KrautKeeper™ holds food fully submerged through the entire process. It works with standard fermentation lids and airlocks for kraut, kimchi, and beyond.

Getting the weight in and out is simple thanks to the center handle. Made to fit jars with a 6.3″ inner diameter, it sits flush and stays in place — no frustration. A smart, no-fuss tool for fermenting foods.

This weight is made for jars with a 110 mm opening or 6.3″ inner diameter, including standard 1-gallon fermenting jars. Whether you’re making sauerkraut or pickled vegetables, it supports clean, hands-off fermentation. For smaller wide-mouth jars, check out our anchor weights.
