Whenever I make a starter, I always decant off the 'beer' and just pitch the slurry. I recently upgraded to a 2L flask, am brewing a 1.078 ale, and according to Mr. Malty I should prepare a 1.7L starter using just one White Labs Vial. My question is: if I'm decanting off the 'beer', what difference does the volume of the starter make, as long as it's around 1.040 OG? Does volume correlate to yeast growth?
