I'm looking to pitch a Wyeast pack that's about six months old into a 1.048 brew. Using Yeastcalc.com with Troester's stir plate method, it says if I make a 1.5L starter that it should bring the cell count up to 260 billion. I'm thinking about stepping it one time just to make sure there is enough viable yeast to do a good job. Thoughts?
Oh... stepping it up with 1L will (should) bring it up to 339 billion. Too much?
