This is my first time using a WLP yeast. I made a 3.7 L starter with two vials of WLP 833 German Bock on a stir plate. I am just starting to see some bubbles after 18 hours where I am used to seeing them well under 12 hours when I use Wyeast 2007 & 2206. I am wondering if the vials that I got have a much lower viability (Use by date 5/14/14 so production 1/14/14 ?) than expected or if this yeast is typically a slow starter. I am planning on harvesting some of this yeast, but don't want to underpitch my beer if the viability was much lower than the yeast calc tools anticipated.
