How can a jar be good for a full year?
In a cold environment (your fridge) the lactic bacteria are dormant but still preserving the cabbage, which is their host. The bacteria actually preserve the cabbage for this purpose. We’ve left experimental jars at room temperature for months with no ill effects. We don’t suggest this but we can assure you if handled well (in your fridge) it will last for about a year. Once you have a taste for it, good luck keeping it around that long (in your fridge).
