How long does my purchased wild ferment from you survive after being opened?Updated a year ago

You are holding a fermented living product in your hands. Especially when stored in the fridge, the shelf life is quite long. However, even though fermented products are naturally less susceptible to mould, this can still happen. So rely on your senses here too. Can you see anything hairy? Then you will have to dispose of your ferment. If not, smell it and try a small piece. Does it taste normal? Bon appétit!
