How to know if Homemade Kraut is bad

[poppylove]

So we just opened our first batch of homemade kraut. Dh made it in a bowl, weighted with another bowl, with a cloth over the top.

We decided to put it in the fridge today. Unfortunately, I come from a "everything comes to you premade" background and I am scared it might have grown some bacteria. How can I tell?

It does smell rotty, but all kraut has a somewhat rotty smell to me

If it smells and tastes like sauerkraut it's probably fine.
