Yes, it's most commonly described as Golden Grahams, or graham cracker with raisins on top of a tobacco base. It does take time for the tobacco flavor to develop, as does most any tobacco juice.
Temper your expectations though. Fresh BB may not be what you're expecting. It's really an enigma ejuice. It's an odd flavor, but it grows on you, changes, and matures over time. I've read alot of new BB vapers dont get all the fuss about it at first, then usually become big BB homers after a while.
Give it a try right away, then put it away for a couple weeks, preferably a month, if you can.
Alot of of BB vapers can't really explain why but we're addicted to it. Objectively speaking, I think I have better juices in my cabinet, yet I crave BB and really look forward to my tank full. Mine's about 6 weeks old though.
