Idea:
A Live Library to keep many different types of yeasts and bacteria used in wine, bier and breads - alive. So when someone wants to make a tasty treat, or beverage they merely need to take a small sample to culture and use.
One may ask, what about this store per-dried yeast stuff?
Well quoting
Matthew Zeits on this:
The freeze dried yeast may get the job done, but at this point the yeast were breed for survival not taste. It's a compromise.
I don't like that compromise.
