Anyone find White Labs WLP051 California V a bit slow to get started? This is the first time I am using this yeast and the SG has not really changed more than 3 points during the first 48 hours. It is in a room at 67 F and all three brews I have made with this seem stuck. I used Mr Malty to do a yeast starter and saw plenty of activity in the starter. It took 30 minutes with my wort chiller to go from 221 F to 95 F but then the water could not really cool much more so I brought it into the basement where it sat for 2 hours prior to reaching 67 F for pitching the yeast. I don't know if this extra lag time was a problem. I did add plenty of O2 with my ss diffusion stone.
I am considering making another 1.5 liter starter and spilitting it between these three 4 gallon batchs to try to get some activity going. Will pitching more yeast at this point damage the beer?
