I made a starter monday for a smack pack of wy2112 that had been expired for a year. should I step it up or do you think there should be enough?
1/2 cup DME
2 cups water
Not sure what you are making or how many cells you need, but you are probably going to have to step it at least once. Check out any of the online calculators to see for sure. The half cup DME 2 cup water might be good enough for the first step but you are probably going to have to go bigger, again depending on what you are making and its OG and if you have a stir plate.
Definitely make another starter (or two?). Get some nutrients in there. Even still, lager yeast are pretty finicky, though I have nearly no experience with the Cal lager strain.
