I have been stating that White Labs vial has an enormous amount of yeast cells for quite some time. In fact, White Labs entered the market with the claim that their cultures were "ready to pitch," which was believable when compared to an original smack pack. Making a starter just gives the culture an opportunity to wake up and double or quadruple in cell count.
I thought a White Labs vial had 70-90 billion cells. For 5 gallons of 1.068 wort wouldn't one need more like 250 billion cells? Mark, are you saying this isn't true? Or is the yeast from White Labs so healthy and ready to go that the cell count doesn't doesn't matter? Or am missing something else? Will there be 250 billion cells by the end of the lag phase? If so, why is it considered best practice to make starters?
