I'm brewing a Pilsner 10 gallon batch this coming saturday and I only have one packet of Saflager S-23 dry yeast. I'm thinking that making a starter would be a good idea and get me up to a cell count that can deal with 10 gallons. True or false?
That said, I have no extract. I'm looking to do a mini mash with a pound of two-row as the starter. Is this enough? If I'm brewing Saturday, should I make the starter on Thursday?
