I should have made it clearer that the scale was 1-10 for straight-up NETs (not hybrids) and not a "no sweetness to high fructose corn syrup! scale." LOL! I would put Devil Dog at a 2-3 and maybe Organic Tobacco #1 at a 2 (from what I remember of OT#1). I read that the varying curing processes of different tobaccos is what transforms certain compounds into sugars; and some tobaccos are just sweetened after the fact. Now, of course, some vendors that are extracting from pre-flavored pipe tobaccos are going to necessarily have sweeter juices due to the added flavorings; but, some tobaccos, due to the curing, will have their own level of sweetness that may, almost, assert itself as "sweetened" when it very well may not be. Fire-curing is supposed to produce a low level of sweetness, but I think Fire-Cured from GeJ is about a 5-6 on the sweetness scale of straight-up NETs. We also must remember that the VG in the juice is also going to lend itself to, if not amplify, the sweetness of a lot of NETs. Seeing as how there aren't many straight PG NETs, most will have some level of sweetness, if not for just the VG.
As an aside, I think the one vendor that produces many NETs that are 1-2 is W2V. Hardly any actual sweetness to those. I think Paris is a 1 on my sacle. Hopefully that gives an indication of how my scale works. What would be a 10 for a straight-up NET? Don't know that I've had it, but it will likely be pre-sweetened.
