This yeast is a very interesting one, it has ginger in it! From a little research into this; it seems that adding ginger to your yeast when blooming it helps it to rise faster and give an added boost to the yeast! The following yeast recipe From Newberry Vermont also has ginger added to it. Very interesting!
For some more information on this method, go to this posting from last year.
