I made a 1.5l starter for a vial of WLP002 (best by Sep/4/2012, so production would be 5/4/2012) and sent it spinning on the stir plate. It took a full day to see some activity, but things came alive and bubbled along. When it was still again I stuck it in the fridge so I can decant and add 1.5l more wort.
When I use yeastcalc, it puts the viability on the vial at 10%, so all of the counts are super low. Is that really what I should expect? I was hoping to freeze some of the yeast before pitching next Monday, but will I be wasting my time?
