Hi, I searched during my lunch break (started at noon PST) and couldn't find anything on this other than using dextrose for the starter. I am wondering if I could take a little bit of my all grain and do a mini-mash to make a starter with. I ordered everything I need for an all grain guinness clone, but completely forgot the DME. I want to be able to brew this weekend but can not go to my LHBS today because I have work from 1-9. Any advice would be great because I want to make my starter tonight when I get off work. Thanks guys. Oh and here is what MrMalty caluclated:
With intermitent shaking, 188 million yeast cells needs, 1.24 liters of started required with 1 vial of White Labs Irish Ale, 4.5 gallons final volume with 1.060 OG. Thanks!
