Fermentaholics KrautKeeper™

The KrautKeeper™ is a simple tool that makes fermenting foods of any kind easier — whether you’re making sauerkraut, kimchi, pickles, or something else. It’s designed to fit snugly into standard 1-gallon jars, or any jar with a 6.3-inch interior diameter, keeping everything fully submerged in brine where it needs to stay. This helps prevent spoilage and keeps the fermentation process on track. Made from food-grade silicone, it’s easy to clean, built to last, and can also be used as a strainer or microwave cover when not in use.

The KrautKeeper™ works best for larger batches — typically half-gallon to gallon-sized ferments. If you’re looking for a solution for wide-mouth mason jars (like quart-size or smaller batches), check out our fermentation anchor weights instead. They’re designed specifically for that size and setup.
