I am using a zip type gallon bag to store my sour dough starter in the fridge. Will it keep working after a week in storage? I take it out of the fridge the night before and feed it two cups flour and two cups lukewarm water.

1Not sure you need to use up that much storage space. For example, I keep about 1/4 cup in fridge storage. I try to feed weekly, sometimes I forget and several weeks pass. It has never failed.– moscafjFeb 4, 2018 at 23:06

@moscafj there are recipes where you make about half the bread volume or more out of starter, so if the OP is baking large loaves, this can be needed. Also, a gallon bag doesn't have to be full to the brim.– rumtscho ♦Feb 5, 2018 at 8:57

One week is fine. I keep my starter also for one week in the fridge and feed it once a week:
- 20g starter
- 50g water
- 50g rye flour
If you want to do it for a longer period, I'd exchange the plastic for glass which is 100% safe from leeching nasty stuff into your starter.
