Why doesn't my water kefir produce carbonic acid?Updated 2 years ago

This can have several causes. Have you taken too little sugar? Are there enough yeasts? Did you close your glass tightly? If your glass is fitted with our fermentation tops, the carbon dioxide can always escape. It only really produces carbonic acid in closed bottles. Second fermentation is very suitable for this. Fill your water kefir into bottles and seal them. After 24 hours, there should already be a lot of fizz on it.
