It is in this fermentation pot to a heavy and solid ceramic work. I have 6 small white cabbage pots in this 10ltr. Pot processed. Groove must always be filled with water. This provides the digestate protection against invading germs, etc. When the vegetables begin to ferment, escape the water bubbles, which sounds funny - at first I wussste this noise does not classify. Am really looking forward to the day when I open the pot. The pot is 39cm high and. Measures 26cm in diameter.
