Yes, there are 3 strains (see the Zymurgy special Yeast issue mentioned
by Noel Damon or a posting to HBD by George Fix). If you've cultivated
it, you likely only have one of the 3 strains (or even a wild yeast!).
I suggest it is not worth the bother to cultivate Whitbread because you
need to grow all 3 strains and then combine them in the right proportion
(which may not be 1:1:1...).

As an experiment, go ahead with a small batch based on your yeast culture.
If it takes off quickly, you have strain #1. If it has a long lag time,
it's #2 or #3.
