Can we talk about using a crock vs a dedicated fermenter for sauerkraut?

I just finished my third batch of kraut, and the difference was huge. For the first two, I used a big old ceramic crock with a water seal, the kind my grandma had. It worked, but I had to top up the water every few days and I lost a whole batch to mold once. This time, I borrowed a friend's airlock fermenter, the kind with the little bubbler lid. I used the same cabbage and salt ratio, about 2.5% by weight. The kraut was ready in 3 weeks, no mold, no scum, and the taste was way cleaner and sharper. The crock felt like guesswork, but the airlock system just felt controlled. Has anyone else switched from a crock to something with an airlock and noticed a big change in how reliable it is?

Totally get the switch. My old crock was a constant battle with kahm yeast and that weird white scum. I even tried the plate and rock method, but it was a mess. The airlock just takes all the worry out. I can leave it in a corner for a month and forget it. Do you think you'll stick with the airlock system now?

Whoa, hold up. I gotta disagree with you guys on this one. The airlock just feels like cheating to me. I actually like checking on my ferments, seeing the bubbles, smelling the changes. That hands on part is the whole point. Sure, I've scraped off some kahm before, but it never ruined a batch. Feels like the airlock takes away the living part of fermenting and turns it into just a jar with a plastic tube.

Oh the "weird white scum" is the worst. I read a blog post that basically said that stuff is a sign you're in a constant fight with oxygen, which totally lines up with what you're saying, @eva_rivera. The airlock just ends that war. Once I switched, it felt less like a science project I had to babysit. I'm definitely sticking with it, no way I'm going back to checking under plates every other day.
