My first kraut volcano happened in a tiny apartment kitchen
It was about eight years ago, I was living in a small place in Tacoma and had just packed my first big crock of sauerkraut. I used a basic recipe, maybe five pounds of cabbage, and thought I had enough headspace. Three days in, I woke up to a real mess. The brine had pushed up through the weight and airlock, dripping down the cabinet and onto the floor. It smelled like a weird, salty garden. I panicked, cleaned it all up with a bunch of old towels, and moved the whole crock into a big plastic tub for the rest of the ferment. That was the moment I learned headspace isn't just a suggestion. Anyone have a good rule of thumb for how much room to leave in a crock?
