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. 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.
