e-jen Premium Kimchi, Sauerkraut Container Probiotic Fermentation with Inner Vacuum Lid (Earthenware Green, 0.9 gal/ 3.4L)

Not a bad idea just can't do large amounts. I'd also look into kimchi fermentation containers, fairly cheap and can get from small quart size to giant 5 gallon models. It actually works similar to French press with a lid that pushes everything down and a vent to purge any air. https://a.co/d/06nvQjx
