Lakeland Fermentation Jar with Air-Release Valve 1.4L 5 "Ideal for all fermentation fans" Mrs Anne Wood 18 February 2021 Since the pandemic began I have tried to make sure that my family have a much healthier diet. Fermented foods such as saurkraut and kimchi improve your gut bacteria which means your immune system benefits too. During lockdown I have experimented with various fermentation recipes, this jar is so useful. It has an excellent wide neck top which is easy to fill and the the air release valve mean you don't have to mess around with ' burping' your produce. I would highly recommend this jar and the smaller size one too.
