Humble House Sauerkrock Water-Seal Fermentation Crock (5 L)
A favorite water-seal crock. The 5-liter size makes a real batch of kraut, it comes with the weight stones that hold the cabbage under the brine, and the water moat lets CO2 burp out while sealing oxygen and mold away. Makers like that the glaze is lead-free and the seal is reliable, so a batch just ferments untouched for weeks.
