I'm looking to save some money while stepping up to 10 gallon all-grain batches. My washed yeast looks great (just like I would get in a vial), but I have never done a starter before. I would love any tips and was wondering if I can just put the DME/boiled & cooled water into the mason jars that the yeastcakes are in, provided the lids are loose. I'll be dividing a 10 gallon boil into 2 6.5 primaries, so should I just do two separate starters or split one? Does it matter?
My primary expertise is in hop cultivation and usage, so any help here would be awesome. My beer budget is shared with my fishing budget, so saving on yeast at double batches seems worth the investigation. Thanks in advance and please forgive my ignorance.
