    So this question came up today while conversing with a fellow brewer.....

    Let's say I make a yeast starter from a white labs vial. What if I put some of the starter back in the vial and in the fridge? (cleaned and sanitized of course). Would it be sufficient to pull it out later and make a new starter from that? Or would it be too diluted to do anything with it? (I'm thinking, diminishing returns, it probably fail pretty quickly unless you did a multi-step starter for something high gravity followed by a lower gravity brew that didn't require as much) ????

    You'd have to know the slurry density to be sure of how many yeast went back into the vial. If it is nicely settled and you decant off the liquid, leaving just the fresh yeast, I'd think replacing an equivalent amount would be pretty close or at least half?
