Does Sauerkraut Get Moldy

Most find it perfectly safe to remove the layer of mold on top of their ferment. This is fine with greenish or grayish mold. However, toss ferments with black, pink or orange mold or if they have an off smell.

How do you know if your sauerkraut is bad?

One of the first signs that the sauerkraut has gone bad is an off-smelling aroma. If the product emits a strong rotting odor, the sauerkraut has gone bad. Check if the fermented cabbage has taken on a weird texture or color. If there’s significant texture or discoloration, discard the product.

What is the white stuff on top of my sauerkraut?

When fermenting vegetables, it is common to notice a white layer forming on top of the liquid after a few days. Often this white film is mistaken for mold, and the entire ferment is discarded. However, the white film is usually a type of yeast known as kahm yeast.
