Sad news: Yesterday I threw both wheels away
The development of the PC was stopped and a terrible smell had developed, together with a very light green mold on the surface where no PC had developed. It's hard to describe the smell, because I'm sure I have never smelled something like that before. First thing that becomes into my mind is a mix of sulphur
and ammonia. I cut them both and took a sample from the inside. Tasted young but really good, but I'm pretty sure nobody could be convinced with that smell that this was something you could eat. Also noticed that it had a lot of tiny eyes.
Could this be caused by the blob of soya yogurt I added with the culture?
Anyway, I spent a couple of hours cleaning my cave with water and vinegar and ventilating the loft where the cave is placed....
