Ahhhh, I see that verbiage now. Thank you for that. I think I am going to enter them both in 30a. The vanilla is just not subtle enough to put it in the Porter category. I also found that in the 2008 guidelines they used a Vanilla Porter as one of the commercial examples for Spice, Herb, or Vegetable beer. Granted, those are the "old" guidelines, I feel comfortable with that decision.
Thanks again for the advice. Cheers!
