The more I read and watch about fermenting the more confused I get. I bought a few glass jars with those fancy airlocks that I see all kinds of YouTubers use and I’m only semi-happy with some of them. I assumed their point is to avoid having to burp the jar. But the more I keep watching the more I come across the actual experts who have been fermenting their whole life who don’t actually use all that fancy stuff. One guy I’ve been watching just uses those Weck glasses with rubber bands and says the rubber seal is weak enough to let gasses out but tight enough to not let air in. Is that true? If so, what’s even the point of those annoying airlocks if an old-fashioned grandma-style Weck jar does the same?
