Hi, I'm new to the forum and to sourdough, though I've been making killer, crusty, yummy artisan breads for several years now. I've a couple, (probably oh, so obvious!), sourdough questions I hope you can help me with.

If someone can help me I have the barm as described in BBA book pg. 230.   After you create it and put it in the fridge overnight it is ready.  But then he says it is good for 3 days before you need to refresh it.  Does that mean it is good for 3 days in the fridge or on the counter?  I think it is on the counter as his side note says you can keep it in the fridge for 2 months in a container?  Any help would be appreciate it.
