Is there any reason I couldn't use the second runnings from my next mash to propagate yeast in the future? I figure that if I sparge a little extra and collect the runoff that wort would be fine to save in a gallon jug. Sure, it might be weak but if I boil it when it's time to grow yeast cells I will A) concentrate the wort, increasing the gravity and B) Sterilize the wort before pitching the White Labs vial. Purchasing and working with DME is annoying.
