Vermillion River is a tough one. Tobacco Absolute? Maybe, but maybe not. Or perhaps just a smidge. Certainly nothing like Mom&Pop or Moondrop, which are TA through-and-through (or, in the case of M&P RYO, Tobacco Extract, TA's rough-and-tumble offspring). I couldn't, however, be certain that the VR Kentucky Blends aren't TA based.
Although it's been stated often in numerous threads that Vermillion River is based on natural extract tobacco, supposedly straight from the horse's mouth of VR's juicemaster, I've never felt convinced. I vaped a lot of the Kentucky Premium series back in 2011---Premium, Vanilla, Maplewood, Blend No. 7, Amaretto. They were darned tasty juices and among my favorites for awhile (along with NLV Bounty Hunter, GOLD, and AVE Boba's), but I don't find myself reaching for any of them much these days. I don't even have any more Boba's, and all the rest---VR and NLV juices---have been sent to the old folks' home, where I visit them for about ten minutes a month. They've all got Alzheimer's now and don't even recognize me. Or maybe it's the other way 'round. Maybe I'm the one who no longer recognizes them! For whatever reason, I've moved on---all those juices are simply not in the same league (they all strike me as TINOs) and have been swept off the table for me by the current generation of NETs.
I agree that VR's Kentucky Premium series are all variations on a theme, like an Italian restaurant that offers 17 different pasta dishes on the menu, every one of which is made with the same marinara sauce. Classic Blend is a bit different, though. I don't recall it having any vanilla. After all, Classic was designed to be VR's attempt at a straight tobacco replicant. Kentucky Premium clearly has some vanilla, and Kentucky Vanilla has a lot, but I don't think Classic has any. I could be wrong, of course.
All right, I just atty-dripped some Classic to refresh my memory, but it's a hung jury. I really can't tell what's in it, except for something vaguely sweet. Doesn't taste like an NET to my brain. Heck, maybe it is TA plus a synthetic tobacco. Lots of other flavors in there as well, though.
While I haven't tried them, I think it more likely from the descriptions I've read that the Poker Blends might be straight NETs.
