Deferring a starter

[ColoradoChuck]

I made a 1L 1.040 starter; the source yeast wasn't too old, and it seemed to ferment well. Life intercedes, and that flask comes to sit covered with foil in my refrigerator.

- How long do I have before it is no longer good to use? Is saving it to a media bottle for a longer storage period a viable option?
- Can I re-pitch to another starter to keep it going, and if so, are there any modifications to technique or timing to be considered?

I have saved harvested yeast for months. Your starter will certainly keep in the fridge for weeks.

if it's just a loose foil cover, maybe stick a rubber band around it to seal it, if it's going to sit there for a long time, bad things(tm) could get inside under a loose cover.
