You want to ferment your sauerkraut for 3-6 weeks. As your sauerkraut is fermenting, keep it out of direct sunlight and have the room temperature around 13C – 22C. Burp your jar regularly, to let gas escape. After 3-6 weeks, remove the bamboo stick and cabbage leaf. You can transfer to another clean jar at this point if you wish, but it’s not necessary. Keep it stored in the fridge and it should last for a couple of months.
