Really? I'd love to get less sour flavour, but proofing overnight (in the fridge) looks like it's really hard to avoid it...

I leave it on the counter overnight. I really have to work at getting any sour flavour at all. My starter smells a little like cotton candy to me though when it's ready to go, floats really well in the water.

I've never got even a slight note or the sour taste from my starter. I guess I was quite lucky with how it developed.
