I've smoked three in my life and have two sitting in my humidor aging as I type this......I haven't smoked one in a couple of months so the taste isn't fresh in my mind.
However, I find they are very similar in flavor to the Siglo VI in most respects. I've smoke a few Cohiba's and they appear to my taste buds to have a familiar flavor amongst the different lines. Perhaps you could call it a "signature" flavor?
They are definitely a great smoke.
