Some question please? Great course but it got me thinking ...
Is there a guide rule for the weight of water to exchange for a given weight of instant/fresh yeast?
When the Yeast water has a nice shiny colony, if one migrates the water to a flour ecology, effectively growing it like a sourdough, how long would you expect it to retain the flavours from the yeast water before a refresh would be required. Obviously it's easier to see the rise in flour than it is in water, and easier to manipulate the yeast/bacteria ratio.
