The best sauerkraut crock uses a water-seal lid so the cabbage can ferment for weeks without mold-friendly air getting in. German-style crocks pioneered this design, and modern versions include split weights that keep shredded cabbage under its brine.
We compared six crocks on Amazon US by seal, capacity and reviews.

How We Chose the Best Sauerkraut Crock
To build this guide to the best sauerkraut crock, we compared fermentation crocks, jars, lids, weights and kits sold on Amazon US by material (stoneware, glass, food-grade plastic and silicone), capacity, water-seal or airlock design, weight fit and cleaning. We then read patterns in verified-buyer reviews for leaks, mold, cracks, odors and fit on standard mason jars, and flagged listings with few ratings.
Use clean equipment, the right salt ratio and keep vegetables under the brine, following USDA Food Safety and Inspection Service cleanliness guidance. Discard batches with fuzzy or colored mold. Our method is explained on the How We Test page; this is a research-based guide, not a lab test.
