Blending - How do the flavors get in there?

[BradNC]

I've been reading on here and on the internet about blending. I'm confused on how these different flavors get in to the tobacco. Is it just between our ears or how do they get a "fruity" or "nutty" taste into the tobacco? Do they keep the blending the same in each cigar line so you know what flavor to expect and when?

I've been smoking cigars for about a year or so I think. Only recently I think I finally figured it out or some of it as far as smoking slow, noticing flavors every once in a while, etc.

Thanks!
