I keep my sourdough starter in a sealed container in the fridge and bring it out a couple of days before using it. I opened the lid of the container and was met by a sharp almost glue-like smell. Oh no is my starter dead?
Or is it possible that by keeping the starter in a sealed container no air can get in or out, so is the smell the gases that have been trapped in the container (is it CO2 that sourdough bacteria give out?) and hopefully the starter can be revived.

Any thoughts
