He said in one episode he wouldn't say. My guess is so it doesn't get all bought up by fans dying to try it lol. If I remember correctly the reason he gave was to not influence peoples decisions on blends. However, if memory serves me correctly, I believe he let it slip that it's a VaPer blend. I intend on patroning the Las Vegas show this year, which Brian said he was attending. Maybe I'll get a better hint in person. Brian did say he's not a fan of English blends and isn't too big on aromatics either. This could be a case of Mr. Owl though, the world may never know.
