Hi!

I have a successful starter that has been in a preserve bottle (with a loose fitting lid) in the fridge for a while. When I opened it today I found that it had made a "skin" on top of the starter and it has a smell that reminds me of acetone (nail polish remover). (I haven't opened it for about 3 weeks.) I have scooped out the skin, given it a stir and it seems as if the acetone smell is dissipating. Is this normal? Or have I lost this one? I have left it out of the fridge to see what it looks like in the morning.

Regards,

Deon
